Description
The ROHO Planar Solid Seat Insert is a flat rigidizer panel that turns a sagging seat into a level surface any cushion can work on. The 16 by 16 inch SI1616 size drops into the seat under the cushion, and the manufacturer rates it without a weight limit when properly sized.
- Use with any seat – ROHO's own description for the Planar insert line, cushion brand aside.
- 16 by 16 inch panel – the SI1616 size for the most common adult wheelchair seat.
- No weight limit – rated without a weight limit when properly sized to the cushion and individual.
- 12 month warranty – covered in the manufacturer's warranty policy by name.
Sling upholstery stretches with use, and every millimetre of sag tilts the pelvis and concentrates pressure. This insert restores a planar surface: a rigid panel sized to the seat that sits under the cushion and stops the hammock effect. ROHO sells the Planar Solid Seat Insert as a general accessory for use with any seat, so it serves ROHO and non-ROHO cushions alike. The stocked SI1616 configuration measures 16 by 16 inches, matching the standard adult wheelchair seat. It is sold as a single panel and needs no fitting beyond choosing the size that matches the seat and cushion footprint.

Why Choose the ROHO Planar Solid Seat Insert?
Before replacing a cushion that feels wrong, it is worth checking the surface under it, because sagging slings imitate cushion failure. This insert is the low cost diagnostic and cure in one panel. And unlike generic boards, it is the cushion manufacturer's own specified part, sized and warranted for the job.
- Fixes the foundation – level support restores the posture and pressure behavior the cushion was chosen for.
- Brand agnostic – ROHO describes the insert for use with any seat, so it upgrades chairs running other cushions too.
- No capacity worry – the no weight limit rating covers bariatric users when the panel is properly sized.
- The differentiator – a warranted, manufacturer made rigidizer, rather than a cut board or plywood substitute.
Frequently Asked Questions
What does a solid seat insert do?
It sits under the cushion and provides a flat, rigid surface, counteracting the hammock effect of stretched sling upholstery. That keeps the pelvis level and lets the cushion load evenly.
What size is stocked?
This listing stocks the SI1616, a 16 by 16 inch panel for standard adult seats. The manufacturer's range includes other sizes that are not part of this listing.
Is there a weight limit?
No. The manufacturer states the insert has no weight limit if it is properly sized to the cushion and the individual.
Can it be used with non-ROHO cushions?
Yes. ROHO describes the Planar Solid Seat Insert for use with any seat, so it works as a rigidizer under other manufacturers' cushions as well.
Is the cushion included?
No. This listing is the insert panel on its own.
What does the warranty cover?
The manufacturer's warranty policy names the Solid Seat Insert with a 12 month limited warranty term from the original purchase date.
