Reformer Bed with Sitting Box
A sitting box is part of how a Pilates reformer gets used, so it pays to choose one with care. We're an Australian owned and operated supplier, and we'll guide you through advice, payment plan options, delivery and installation for your home or studio.
What a sitting box adds to a reformer bed
The box sits on or alongside the carriage
A sitting box is a padded platform that rests on or beside the carriage of your reformer bed. It gives you a stable, raised seat, which opens up seated, stretching and balance work that the carriage alone can't support.
It isn't bolted on, so you can position it where the exercise needs it and move it aside when you don't.
Useful apparatus, not an accessory
Many classical Pilates sequences depend on a sitting box, the short box series being a prime example. Seated rowing and spine twists also need that elevated position, which is hard to replicate lying flat.
Start with how you'll use it. If seated and kneeling work is part of your routine, a sitting box is part of the setup.

As with any Pilates equipment, proper form and qualified instruction matter when you use one.
Exercises a sitting box makes possible
A sitting box opens up seated, kneeling and standing work that a flat carriage can't support. Anyone recovering from an injury should get clearance from a physiotherapist or doctor first.
- Seated rowing: a stable, elevated seat lets you work with the ropes or straps in ways that aren't possible lying flat.
- Spine twists: sitting tall on the box gives you a defined base for rotational movements.
- Short box abdominal series: a staple of classical Pilates sequences, and the reason we treat the box as apparatus rather than an accessory.
- Kneeling and standing work: the box doubles as a step or platform where you need a firmer, higher base than the carriage provides.
Small or large: which size suits you?
Choose the small sitting box if you want something compact and easy to store, and the Pioneer Pilates large sitting box if you're taller or want more surface area. Both are built for the same seated, kneeling and standing work. The difference is size and how you'll use the space around your reformer.
The small box measures 70x40x30 cm. It's light, simple to move, and suits many seated exercises and shorter torso lengths. It's also the one we recommend for our foldable reformer range.
The large box measures 71x44x25 cm. It gives you a wider surface and a platform that sits higher, which helps taller users and exercises that call for extra stability.
Many home users only need one box, matched to their height and favourite exercises. Studios with a mix of client heights often stock both.
Check the build before you buy
Two things tell you a lot about a sitting box: the foam inside and the cover outside. The Pioneer Pilates Large Sitting Box uses specialty EVA foam that resists deforming in use, so the top stays supportive session after session.
For the cover, look for nautical-grade synthetic leather with a stitched seam. That's what the Pioneer large box has, and the stitching adds strength where the box takes heavy wear.
The small sitting box is built the same way: EVA padded, with nautical synthetic leather and a stitched seam. Whichever size of pilates box you choose, check the finish in person at our Sydney showroom if you can.
Will a sitting box fit my reformer?
Probably, yes. A sitting box rests on or alongside the carriage rather than bolting to a specific frame, so many standard-width reformers take one without modification.
The catch is that carriage length and footbar clearance vary by brand, and the differences stand out on older or imported models. Check your dimensions first. Pairing a box with one from the same range, such as Pioneer Pilates and Motion Pilates, is a reliable way to be sure it fits.
If you're buying new, the MP-01 Wood Reformer package bundles a large sitting box with the jump board, padded standing platform, foot strap, ropes and hand straps.
Sitting box questions we hear often
Do I need both sizes for home use?
Usually not. Home users typically need one size matched to their height and favourite exercises. Studios with varied client heights often stock both the small box and the large box.
Does a studio need a different sitting box from a home setup?
The box itself is much the same. Studios tend to want both sizes to cover different bodies and abilities, while a home setup rarely does.
Where do I store a sitting box?
The small box is compact and easy to store and move, so it suits tighter spaces. The large box takes more room. Both can sit alongside the reformer when not in use.
