Best Pilates tower springs are not simply the strongest springs you can buy.
The right spring needs to match the tower, mounting system, spring length, resistance and intended exercise configuration. A spring that works perfectly on one Pilates tower may be completely wrong for another.
That matters because tower and wall-unit springs are loaded repeatedly during exercises involving the arms, legs, trunk and spine. The spring is not just an accessory. It is part of the resistance system.
Balanced Body, for example, sells dedicated Wall Tower Springs for its Wall Tower and notes that the same spring family is also used on its Trapeze Tables and Reformer Trapeze Combination.
Merrithew uses a different replacement system for its Tower Trainer, Vertical Frame, Wall Unit and Spring Wall equipment, with model-specific spring packages and individual spring pairs.
So if you are replacing worn springs, upgrading an older tower or building a studio, compatibility comes first.
Quick Answer: What Are the Best Pilates Tower Springs?
The best Pilates tower springs are manufacturer-compatible springs designed for the exact tower, wall unit, Cadillac or vertical-frame system you own.
For a Balanced Body Wall Tower, the appropriate Wall Tower Springs are the logical starting point. Balanced Body specifies particular short and long spring configurations for its Wall Tower.
For Merrithew Tower Trainer or Vertical Frame equipment, the manufacturer sells a dedicated replacement package containing green, blue, black and yellow spring pairs plus clips.
The important distinction is that Pilates tower springs are not universal.
The best Pilates tower springs are the ones that restore the intended resistance and attachment configuration of your equipment.

Why Pilates Tower Springs Matter
A Pilates tower expands the exercise possibilities available from a mat, reformer, Cadillac or wall-mounted system.
But that versatility depends heavily on the spring system.
A tower may have multiple attachment points and use different springs for different exercises. The resistance can change depending on the spring, its length, where it is attached and how far it is stretched.
That means a tower spring is not just “heavy” or “light.”
Its behavior is part of the equipment’s overall design.
This is particularly important for instructors who teach multiple clients throughout the day. If a spring configuration changes, the resistance experienced by the client changes with it.
For that reason, the best Pilates tower springs should be selected according to the manufacturer’s intended configuration rather than by generic resistance labels.
What Makes the Best Pilates Tower Springs?
Several characteristics matter.
Correct resistance
The spring needs to produce the resistance intended for the equipment.
More resistance is not automatically better.
A spring that is too strong can make an exercise unnecessarily difficult. A spring that is too light can change the exercise’s intended challenge.
Correct length
Tower systems can use springs of different lengths.
Long and short springs are not interchangeable simply because their hooks appear similar.
Balanced Body’s Wall Tower, for example, uses both regular and long springs in its supplied configuration.
Correct hook and clip configuration
The spring needs to attach securely to the tower and any associated handles, bars or straps.
The hook and clip system must be compatible with the equipment.
Appropriate spring construction
Quality springs need to withstand repeated loading.
Balanced Body says its Wall Tower Springs are developed specifically for Pilates use and manufactured with an emphasis on strength, resilience and durability.
Merrithew states that its Tower Trainer replacement springs are nickel-plated and heat-treated to protect the spring material and maintain tension characteristics.
Consistent resistance
Consistency matters just as much as maximum resistance.
An instructor should be able to select a known spring configuration and expect predictable resistance.
Are Pilates Tower Springs Universal?
No.
This is the first thing to establish before ordering.
Different manufacturers use different:
- Spring rates
- Spring lengths
- Hook designs
- Attachment systems
- Color systems
- Resistance classifications
- Mounting positions
- Replacement intervals
Merrithew explicitly states that its replacement parts are intended for Merrithew/STOTT PILATES equipment and will not fit equipment from other manufacturers.
Balanced Body also provides specific Wall Tower spring configurations rather than describing its springs as universal Pilates springs.
So “Pilates tower spring” is not enough information to order the correct part.
You need the equipment manufacturer and model.
Balanced Body Wall Tower Springs
Balanced Body’s Wall Tower is a compact wall-mounted system designed to provide many of the exercise capabilities associated with larger trapeze-table setups.
The current Wall Tower has 23 spring attachment points and includes eight Balanced Body Signature Springs. The supplied configuration includes regular and long springs in different resistance levels.
Balanced Body sells dedicated Wall Tower Springs individually.
The manufacturer lists this standard configuration:
- 2 yellow regular springs
- 2 blue regular springs
- 2 yellow long springs
- 2 purple long springs
The yellow springs are categorized as very light, blue as light and purple as medium within the Balanced Body system.
This is an important example of why counting springs is not enough.
You also need to know which spring goes where.
Balanced Body Wall Tower replacement
If you own a Balanced Body Wall Tower, the dedicated Pilates Wall Tower Springs are the appropriate product category to investigate.
Balanced Body specifically states that its Wall Tower Springs are also used on its Trapeze Tables and Reformer Trapeze Combination.
That means the same spring family can cover more than one piece of equipment within the Balanced Body ecosystem.
It does not mean that every spring from every Pilates manufacturer is interchangeable.
Merrithew Tower Trainer Springs
Merrithew uses a separate spring system.
Its current Vertical Frame and Tower Trainer replacement package contains:
- 2 enhanced leg springs, green
- 2 push-through springs, blue
- 2 roll-down springs, black
- 2 light arm springs, yellow
- 2 locking spring clips
- 12 carabiner spring clips
Merrithew lists the complete Tower Trainer package at $500 on its current site.
The company also sells the individual spring pairs separately through its replacement-parts catalog.
That is useful if one specific spring pair needs replacement rather than the entire set.
Merrithew spring categories
The naming is particularly useful because the springs correspond to different functional categories.
Green: Enhanced Leg Spring
Blue: Push-Thru Spring
Black: Roll-Down Spring
Yellow: Light Arm Spring
This makes it easier to understand why randomly substituting springs is a bad idea.
The color is not merely decorative. It identifies a particular spring within the manufacturer’s system.
Best Pilates Tower Springs for Wall Units
Wall units are another area where compatibility matters.
Merrithew lists a dedicated Wall Unit Spring Package alongside its Tower Trainer and Spring Wall replacement packages. The current catalog lists the Wall Unit package at $630.
The same catalog distinguishes between:
- Cadillac spring packages
- Vertical Frame/Tower Trainer packages
- Wall Unit packages
- Spring Wall packages
That distinction matters.
A Wall Unit spring package should not automatically be assumed to fit a Tower Trainer simply because both are used for tower-style Pilates exercises.
If you have a Merrithew system, use the manufacturer’s equipment identification information before ordering.
Best Pilates Tower Springs for Cadillac Equipment
Cadillac and trapeze equipment can use multiple spring types.
Balanced Body identifies its Wall Tower Springs as also being used on its Trapeze Tables and Reformer Trapeze Combination.
Merrithew, meanwhile, lists a dedicated Cadillac spring package and separate spring types for its Vertical Frame equipment.
That gives buyers an important rule:
Cadillac springs and tower springs can be related, but they are not automatically universal.
Check the exact manufacturer and equipment configuration.
If you are buying a new system rather than replacement springs, you can compare options such as the Reformer Trapeze Combination and CenterLine Cadillac.
Long vs Short Pilates Tower Springs
Spring length is one of the most commonly overlooked specifications.
A longer spring provides a different working range from a shorter spring.
That affects where it can be attached and how it behaves during an exercise.
Balanced Body’s Wall Tower includes both regular and long springs.
That is intentional.
The long springs are not simply “better versions” of the regular springs. They serve different positions and exercises.
Before buying replacement springs, compare:
- Original spring length
- Replacement spring length
- Attachment location
- Manufacturer specifications
- Intended exercise configuration
Do not substitute based solely on color.
Pilates Tower Spring Resistance
Resistance terminology varies between manufacturers.
One company’s yellow spring does not necessarily equal another company’s yellow spring.
This is why spring color should be treated as a manufacturer-specific identification system rather than a universal resistance standard.
Balanced Body identifies its Wall Tower springs using colors such as yellow, blue and purple, while Merrithew uses yellow, blue, black and green for its Tower Trainer configuration.
Those color systems should not be mixed.
If you move from one manufacturer to another, learn the new equipment’s spring system rather than carrying assumptions from your previous equipment.
How to Choose the Best Pilates Tower Springs
Use this process.
1. Identify the manufacturer
Start with the logo, model name or original purchase documentation.
2. Identify the exact equipment
Determine whether you have:
- Wall Tower
- Tower Trainer
- Vertical Frame
- Wall Unit
- Spring Wall
- Cadillac
- Reformer Trapeze Combination
- Another tower-style system
3. Check the serial number
This can be particularly useful with Merrithew equipment.
Merrithew provides serial-number locations for its Vertical Frame, Wall Unit, Spring Wall and Tower Trainer equipment.
The company also asks customers to include the equipment serial number when purchasing replacement springs so the correct springs can be matched to the equipment.
4. Photograph the existing setup
Before removing anything, photograph:
- Each spring
- Each attachment point
- Spring colors
- Clips
- Bars
- Spring positions
This is especially useful when replacing an entire set.
5. Determine what actually needs replacing
You may need:
- One spring
- One pair
- Several springs
- Complete spring package
- Clips
- Safety chain
- Spring covers
Do not automatically replace the entire tower.
6. Verify the spring length
Especially important when both long and regular springs are available.
7. Verify resistance
Match the manufacturer’s spring classification.
8. Check replacement intervals
Spring replacement is preventive maintenance, not simply emergency repair.
How Often Should Pilates Tower Springs Be Replaced?
There is no single replacement interval across every manufacturer.
Merrithew provides a clear recommendation: springs on its spring-loaded equipment should be replaced every two years. The company’s warranty documentation specifically includes Tower Trainers, Wall Units, Spring Walls and other spring-loaded equipment.
Merrithew also recommends replacing clips annually in its Tower Trainer replacement package guidance.
Balanced Body provides warranty information for its Signature Springs based on invoice date and usage. Its Wall Tower spring documentation states a limited warranty of two years from invoice date or 3,000 hours of use when used with four reformers or fewer, with a one-year limited warranty in group settings involving five or more reformers.
The exact replacement schedule should therefore follow the equipment manufacturer’s documentation.
Signs Your Pilates Tower Springs Need Replacement
Look for:
Corrosion
Visible corrosion should never be ignored on a loaded spring.
Damaged hooks
A compromised hook can affect attachment security.
Deformed coils
If the spring no longer maintains its normal shape, investigate it.
Unusual noise
A change in noise can indicate a developing equipment issue.
Changed resistance
If a familiar exercise suddenly feels substantially different, inspect the spring system.
Uneven spring behavior
If one spring appears to behave differently from its paired spring, investigate before continued use.
Excessive age
A spring may look acceptable while still being beyond the manufacturer’s recommended replacement interval.
Should You Replace All Pilates Tower Springs at Once?
Not always.
If one spring is damaged and the rest of the set is relatively new, an individual replacement may make sense.
But if the entire set has reached its service interval, replacing everything can restore a more consistent system.
This is particularly relevant in studios.
Imagine a tower with eight springs of different ages.
Even if none has visibly failed, replacing only one can leave you with a mixture of old and new components.
For high-use equipment, planned replacement is generally easier to manage than waiting for individual failures.
Should Pilates Tower Springs Be Replaced in Pairs?
It depends on the manufacturer’s system.
Some manufacturers sell certain tower springs as pairs.
Merrithew’s Tower Trainer replacement components include individual spring pairs such as its enhanced leg, light arm, push-through and roll-down springs.
Balanced Body sells its Wall Tower Springs individually.
So do not assume that every manufacturer expects springs to be purchased in pairs.
Follow the original equipment configuration.
Why Generic Tower Springs Are Risky
A generic spring might fit the hook.
That does not prove that it is suitable.
The spring could have:
- Different initial tension
- Different spring rate
- Different length
- Different coil diameter
- Different hook geometry
- Different fatigue characteristics
That can change the way the tower behaves.
The small savings from a generic component can therefore create a much bigger problem if the spring is incompatible.
For equipment used professionally, manufacturer-compatible replacements are the safer purchasing approach.
Best Pilates Tower Springs for Home Use
Home users should focus on simplicity.
You generally want:
- Correct manufacturer
- Correct model
- Correct spring type
- Correct length
- Correct attachment
- Proper replacement schedule
Keep your original equipment documentation.
If you purchase a used tower, ask the seller when the springs were last replaced.
If they do not know, treat the springs as an unknown maintenance item rather than assuming they are fine.
That can be especially important when buying older equipment that has spent years in a studio.
Best Pilates Tower Springs for Studios
Studios need a more structured approach.
Maintain a replacement log for every tower.
Record:
Equipment:
Wall Tower, Cadillac, Tower Trainer, etc.
Manufacturer:
Balanced Body, Merrithew or another brand
Model:
Exact equipment name
Serial number:
Record it
Spring configuration:
List each spring
Installation date:
Record when springs were installed
Inspection date:
Schedule regular checks
Replacement date:
Track the manufacturer’s interval
This turns spring maintenance from guesswork into equipment management.
Pilates Tower Spring Clips Matter Too
Springs are not the only components worth inspecting.
Clips are also subjected to repeated loading.
Merrithew specifically recommends replacing clips every year for its Tower Trainer spring system.
Its replacement catalog includes both carabiner spring clips and locking spring clips.
If the spring itself looks fine but the clip is worn, do not ignore the clip.
A spring system is only as secure as its attachment components.
Spring Covers and Protective Accessories
Some systems use spring covers or protective components.
These can help protect the equipment and make the spring system easier to handle.
Merrithew, for example, lists vinyl spring covers among its Cadillac, Spring Wall and Wall Unit replacement accessories.
However, do not install an aftermarket cover simply because it looks compatible.
Anything around a moving spring needs to remain clear of the spring’s working range.
Wall Tower Spring Configuration Example
Balanced Body provides a useful example of how specific these systems can be.
Its Wall Tower comes with eight Signature Springs:
- 2 regular yellow
- 2 regular blue
- 2 long yellow
- 2 long purple
The Wall Tower itself has 23 spring attachment points.
That means the spring system is designed to give the instructor a wide range of attachment options.
The number of springs does not tell the whole story.
Their length, resistance and attachment position matter too.
Merrithew Tower Trainer Configuration Example
Merrithew’s complete Tower Trainer/Vertical Frame replacement package demonstrates the same principle.
The package contains four different spring categories:
- Enhanced Leg
- Push-Thru
- Roll-Down
- Light Arm
It also contains the appropriate spring clips.
This is why purchasing a random collection of springs based on color or appearance is a poor strategy.
The manufacturer has designed the complete system around specific spring types.
Buying Used Pilates Tower Equipment
If you’re buying a used tower, inspect the springs before judging the equipment’s value.
Ask:
- How old is the tower?
- How old are the springs?
- Were the springs replaced?
- How often was the equipment used?
- Was it used commercially?
- Are all original springs included?
- Are any clips missing?
- Are there visible signs of corrosion?
- Does the tower have its original mounting hardware?
- Is the serial number available?
A tower with old springs is not necessarily a bad purchase.
But replacement springs should be included in your ownership cost.
The same principle applies when buying a used Reformer Trapeze Combination.
Best Pilates Tower Springs: What to Avoid
Avoid these mistakes.
Buying by color alone
Colors are manufacturer-specific.
Buying by length alone
Two springs with the same length can have different resistance characteristics.
Assuming Cadillac and tower springs are interchangeable
Sometimes a manufacturer uses the same spring family across equipment. Sometimes it does not.
Verify.
Mixing manufacturers
Do not mix spring systems simply because the hardware appears compatible.
Ignoring the clips
Clips are part of the attachment system.
Waiting for a spring to break
Preventive replacement is preferable to failure during use.
Buying the cheapest spring available
The cheapest component is not necessarily the cheapest solution.
Forgetting the serial number
On some equipment, the serial number can help the manufacturer identify the appropriate replacement package.
Where to Buy Pilates Tower Springs
The Reformer Shop carries Pilates Wall Tower Springs for buyers looking for tower replacement components.
You can also compare complete tower and Cadillac systems, including the Reformer Trapeze Combination and CenterLine Cadillac.
For Balanced Body equipment, verify the exact spring configuration against the manufacturer’s current Wall Tower documentation.
For Merrithew equipment, use the manufacturer’s replacement-parts catalog and provide the equipment serial number when required.
Frequently Asked Questions
What are the best Pilates tower springs?
The best Pilates tower springs are manufacturer-compatible springs that match the exact tower, mounting system, length and resistance requirements.
Are Pilates tower springs universal?
No. Different manufacturers use different spring rates, dimensions, colors, hooks and attachment systems.
What springs does a Balanced Body Wall Tower use?
Balanced Body’s Wall Tower uses eight Signature Springs in its standard configuration: two regular yellow, two regular blue, two long yellow and two long purple springs.
How often should Pilates tower springs be replaced?
Follow the manufacturer’s instructions. Merrithew recommends replacing springs on its spring-loaded equipment every two years.
Are Cadillac springs the same as tower springs?
Not universally. Some manufacturers use the same spring family across multiple pieces of equipment, while others use equipment-specific springs.
Can I use reformer springs on a Pilates tower?
Do not assume so. Reformer springs and tower springs can have different lengths, resistance characteristics and attachment systems.
Are long Pilates springs better than short springs?
No. They serve different purposes. The correct length depends on the equipment and attachment position.
Can I replace only one Pilates tower spring?
Sometimes. Balanced Body sells its Wall Tower Springs individually, while Merrithew offers several Tower Trainer spring types as pairs.
Do tower spring clips need replacement?
Yes, they should be inspected regularly. Merrithew recommends replacing clips annually for its Tower Trainer spring system.
How do I identify the correct Merrithew tower springs?
Identify the equipment and serial number. Merrithew provides serial-number locations and asks customers to include the serial number with replacement-spring purchases.
What should I do if my tower springs look old but are not broken?
Check the manufacturer’s replacement schedule and inspect the springs and attachment hardware. Springs do not need to visibly fail before they are due for replacement.
Final Buying Checklist
Before ordering Pilates tower springs, confirm:
□ Manufacturer
□ Exact equipment model
□ Serial number
□ Spring length
□ Spring resistance
□ Spring color according to that manufacturer’s system
□ Hook configuration
□ Attachment points
□ Number of springs required
□ Individual vs pair vs complete package
□ Spring replacement interval
□ Clip condition
□ Installation instructions
The biggest mistake is treating tower springs like generic hardware.
They are part of the resistance system.
Balanced Body’s Wall Tower uses a defined combination of regular and long springs, while Merrithew’s Tower Trainer uses a different set of color-coded spring categories.
That difference tells you everything you need to know about shopping for replacement springs.
Identify the equipment first. Match the spring second.
Do that, and you avoid the most common tower-spring buying mistake: purchasing something that technically attaches but does not actually belong on the equipment.
