Beyond the reformer itself, accessories expand the range of exercises, accommodate different body types, and increase class variety. For studio owners, understanding which accessories to stock and how they integrate with the reformer is essential for maximising equipment utilisation and client satisfaction.
This catalogue covers the four main Pilates reformer accessories — boxes, jump boards, platform extenders, and foam roller covers with eco-friendly mats — including specifications, exercise applications, and purchasing guidance for commercial studios.
Reformer Box
The reformer box, also called a Pilates box or short box, is a padded platform that sits on the carriage to enable seated and lying exercises at different heights. The standard box measures approximately 48 × 33 × 12 cm with a weight of 5–7 kg. Foam padding should be high-density (50–60 kg/m³) to resist compression under daily commercial use. The cover should be marine-grade vinyl with antimicrobial treatment, matching the reformer upholstery.
Boxes are available in two height configurations: standard height (12 cm) for seated spine stretches, hip openers, lateral flexion, and side-lying series; and low profile (8 cm) for clients with limited hip mobility, post-natal clients, or those transitioning from mat work to reformer. Some manufacturers offer adjustable-height boxes with interchangeable foam blocks that lock into position with a pin mechanism.
Exercise applications for the box include: seated spine stretch forward (hamstring and spinal mobility), hip opener (external rotation with spring resistance), lateral flexion (oblique strengthening), side-lying leg lifts (hip abductor activation), and mermaid stretch (lateral spinal mobility). Box exercises account for approximately 15–20% of a typical reformer class sequence.

Box Padding and Density Specifications
When purchasing boxes for a studio, verify that the bottom surface has non-slip rubber grips compatible with your carriage surface material. A box that slides during use creates a safety hazard — the client may lose balance during seated exercises. Check that the carrying handles are securely anchored with reinforced stitching or riveted attachment points. Handles should withstand a pull force of at least 50 kg without tearing.
Jump Board
The jump board converts the reformer into a low-impact cardio platform. It attaches to the footbar with locking brackets and provides a padded surface for jumping, bouncing, and rebounding exercises. Typical jump board dimensions: 45–55 cm wide by 30–40 cm deep. Weight: 3–5 kg.
Key specifications for commercial jump boards include: minimum 50 mm shock-absorbing foam with a density of 40–50 kg/m³ to prevent bottoming out during impact; marine-grade vinyl cover with antimicrobial treatment to resist sweat and bacterial growth; reinforced attachment brackets compatible with standard footbar widths of 30–38 cm; and a load rating of 200 kg+ to safely accommodate all body types during dynamic impact. Jump board foam compresses approximately 10–15% during normal use and should be replaced every 2–3 years.
Jump boards significantly expand class programming options. Studios can offer dedicated cardio-reformer classes, HIIT-reformer fusion formats, athletic conditioning sessions for sports teams, and low-impact cardiovascular training for older adults or those with joint concerns. The jump board enables exercises such as: basic jumps (two-foot take-off and landing), single-leg hops (balance and ankle stability), lateral shuffles (agility training), and plyometric squat jumps (power development).
Jump Board Dimensions and Compatibility
Safety Features for Jump Board Use
Safety note: jump board classes require reformers with a minimum 250 kg frame rating to handle the repetitive dynamic loads. Studios should also ensure the ceiling height is adequate — jumping clients need at least 30 cm of clearance above their maximum jump height.
Platform Extender
A platform extender lengthens the carriage surface by 15–30 cm, providing additional space for tall clients or exercises requiring more body length on the carriage. Standard carriages measure 95–105 cm, which is too short for comfortable prone and supine exercises for clients over 185 cm. The extender attaches to the head end of the carriage with locking brackets or strap-secured connections.
When selecting a platform extender, verify compatibility with your specific reformer model. The attachment mechanism should be tool-free and secure enough to prevent movement during dynamic exercises — shifting of even 1 cm during an exercise is distracting and potentially unsafe. The padding should match the carriage pad in thickness (typically 3–5 cm) and firmness (ILD 30–40) for a seamless client experience.
Extended Carriage for Taller Clients
Platform Extender Installation Guide
Platform extenders are particularly valuable in studios serving a diverse height range. While the average carriage suits clients up to 178 cm comfortably, extending the surface to 120–130 cm accommodates clients up to 200 cm. For studios with a significant male client base (who tend to be taller on average), platform extenders should be standard equipment on at least half the reformers.
Foam Roller Covers and Eco-Friendly Mats
Foam roller covers protect the roller surface and provide a hygienic barrier between clients. Standard covers fit 90 cm and 60 cm rollers with diameters of 13–15 cm. Commercial-grade covers use 4-way stretch polyester or nylon-spandex blends with antimicrobial finishes to prevent bacterial growth from sweat absorption. Covers should be machine-washable and replaced every 6–12 months depending on usage frequency. Cost: ¥30–80 per cover from bulk suppliers.
Eco-friendly Pilates mats complement the reformer for warm-ups, cool-downs, and mat-based segments of reformer classes. Natural rubber mats (3–5 mm thickness) provide excellent grip — wet grip improves as the rubber surface is activated by moisture — and are biodegradable at end of life. TPE (thermoplastic elastomer) mats offer a lightweight, recyclable alternative at a lower cost point. Cork mats combine a sustainable cork surface with a natural rubber base, providing natural antimicrobial properties. Each material has trade-offs: natural rubber is heaviest but most durable (3–5 years), TPE is lightest and most affordable (1–2 years), and cork offers the best grip-to-weight ratio (2–3 years). Studio owners can specify custom colours and logo printing for covers and mats. Minimum order quantities for custom accessories are typically 100–200 units when sourcing directly from Guangzhou manufacturers.

Accessory Storage and Organisation
Accessory management is an overlooked aspect of studio operations that directly affects class efficiency. Without organised storage, accessories get misplaced, damaged, or under-utilised.
Wall-Mounted Storage Solutions
Mobile Storage Cart Systems
Recommended storage solutions include: wall-mounted shelving units positioned near the reformer area (not in a back room or storage closet); colour-coded systems where each reformer station has a colour and matching accessories; and per-reformer baskets or bins for small accessories such as straps, rings, and bands. Budget ¥3,000–6,000 for accessory storage in a 10-reformer studio — this investment extends accessory life and reduces class transition time.
Summary
Boxes, jump boards, platform extenders, and eco-friendly mats are essential accessories that maximise the versatility of your Pilates reformers. Invest in commercial-grade accessories with appropriate foam density, cover materials, and secure attachment mechanisms. Organise accessories with a colour-coded storage system to streamline class operations. Factory-direct pricing from Guangzhou manufacturers delivers significant savings on bulk accessory orders.
