Description
The ROHO Contour Base is the rigid platform that gives a ROHO cushion a flat, stable foundation on a sling seat wheelchair. Without it, a sling seat hammocks under the cushion and quietly undoes the positioning and pressure work the cushion was fitted to do.
- Made for sling seats – use the Contour Base with a sling seat instead of placing the cushion on sagging upholstery.
- 17 by 15.25 inch size – the BASE1715 platform suits common adult seat widths.
- Part of the ROHO system – listed by ROHO as the companion accessory across its cushion order forms.
- Low, light platform – adds a foundation without turning the chair into a solid seat conversion project.
Every ROHO cushion assumes a reasonably flat seat beneath it, and a stretched sling seat is anything but flat. The Contour Base sits on the sling and presents that flat surface, so the cushion's cells load evenly and the user's pelvis stays where the seating plan put it. ROHO lists the Contour Base on the order forms for its cushion lines as the base to use with sling seats, which makes it the manufacturer specified answer rather than a workshop improvisation. This listing stocks the BASE1715 size, 17 inches wide by 15.25 inches deep, fitting the common 16 to 18 inch seat range. It is sold as a single platform and works under any ROHO cushion of matching footprint.

Why Choose the ROHO Contour Base?
A premium cushion on a sagging sling is a compromised system, and the failure is silent: nobody sees the hammock under the cushion. The Contour Base is the inexpensive half of the system that lets the expensive half work. Seating clinics spec it routinely, and this is the genuine ROHO part they spec.
- Protects the cushion's work – even cell loading keeps pressure redistribution and positioning behaving as fitted.
- Cheaper than a seat conversion – a drop in platform achieves the flat foundation without replacing the chair's seat.
- Genuine ROHO accessory – the same base ROHO lists on its own cushion order forms, in the BASE1715 size.
- The differentiator – it is the only rigidizer in this catalog made by the cushion manufacturer for its own cushions.
Frequently Asked Questions
When is a Contour Base needed?
When a ROHO cushion will sit on a sling seat wheelchair. The base gives the cushion a flat platform so the sling cannot hammock underneath it and distort positioning.
What size is stocked?
This listing stocks BASE1715, which measures 17 inches wide by 15.25 inches deep. Other base sizes exist in the manufacturer's range but are not part of this listing.
Does it replace the cushion?
No. The base goes under the cushion, between the sling seat and the cushion itself. The cushion is sold separately.
Which cushions can sit on it?
Any ROHO cushion with a footprint close to the platform size, which covers most 16 to 18 inch seat cushions in this catalog. The base is listed by ROHO across its cushion order forms for sling seat use.
Is the cushion included?
No. This listing is the Contour Base platform on its own.
How is the base installed?
Place the base on the sling seat platform area, then set the cushion on top of it with the non-skid cover bottom facing down. No tools or hardware are involved.
