Prism Basic Back

The Prism Basic Back is a Future Mobility wheelchair back support for mild to moderate postural support. Westin Healthcare fits it in Brampton and across the Greater Toronto Area.

A 5052 aluminum shell, replaceable foam, and quick-release cane clamps give a rigid back without built-in laterals. Future Mobility ships stock, non-stock, custom, and bariatric widths. Choose Cushion Size follows the non-stock band. Ask us if you need a stock pair, a custom cut, or a 21-24 in bariatric shell.

Who this back support is for

This wheelchair back support is for a person who needs a firm foam shell and a settable angle, at or under 250 lb (113 kg) on standard widths or 350 lb (159 kg) on bariatric widths, and who does not need tall laterals. Families usually call us when the sling on the chair hammocks or the person needs a quick-release rigid back for a folding frame.

If the therapist wants 6 in laterals, use the Prism Ultra Back. If they want air laterals, use the Prism Air Back. If they want rebuildable cubes, use the Prism Truefitt Back.

• Mild to moderate postural support, as Future Mobility states it
• No factory laterals on this model
• Hardware that comes off the canes for folding or transfer

Shell, foam, and hardware

The shell is 5052 aluminum. Foam is replaceable. The cover is a 4-way stretch outer; an infection-control cover is the other factory option. Future Mobility's user manual says to keep the cover on and to wash it cold on a gentle cycle, then air dry.

Cane-clamp hardware is included. Clamps fit 1 in (25 mm) posts, with inserts for 7/8 in (22 mm). The brochure also lists 3/4 in (19 mm) tubing. The silver flip releases the shell. Three Allen screws set height. Angle is 15 degrees forward and 20 degrees back, with a 5 in (127 mm) forward and rear range. Pins take up to 2 in (51 mm) of seat-width difference. Future Mobility prints that the back can be adjusted while the person stays in the chair. A seating therapist should make the first set.

Prism Basic, Ultra, Air, or Truefitt

The Prism Basic Back is the entry rigid shell on this ladder. The Prism Ultra Back keeps the same hardware and adds 6 in laterals. The Prism Air Back adds air laterals and lumbar. The Prism Truefitt Back rebuilds with foam cubes. The Prism Adjustable Tension Backrest is the strap back when a rigid shell is more than the person needs.

Funding help for a wheelchair cushion or back support in Ontario

This cushion or back support is an ADP positioning device category item. Ontario's Assistive Devices Program (ADP) can fund 75% of the cost of positioning devices such as cushions and back supports when they are prescribed through an assessment by an ADP-registered occupational therapist or physiotherapist with an eligible mobility device, and some income-support programs cover the full cost. Not every product qualifies, so talk to us before you buy. March of Dimes Canada, Veterans Affairs Canada (VAC), and community programs can also help. Westin Healthcare's staff work with these programs every week and will point you to the right route for your situation. Visit our funding page or call (905) 451-7743 to talk it through.

Delivery and setup in Brampton and the GTA

Westin's own team delivers this wheelchair back support across Brampton and the Greater Toronto Area. We bring it in, fit the clamps when the hardware allows, and show you the latch before we leave.

We have three stores in the Brampton and Toronto area if you would rather see a back support first. For a scheduled in-home setup, call (905) 451-7743 and we will book the next date that works. Same-day delivery is offered through our hospital bed rental service; purchased seating is delivered on a scheduled date.

This back support is smaller than a hospital bed. If it is going outside the GTA, ask us about parcel or freight shipping. Inside Toronto and the GTA, White-Glove Delivery (bring-in, unwrap, test, take packaging away) is described on the shipping policy. Any charge is confirmed on your order.

Service and warranty

When something on the back support needs work, you call the shop that set it up, not a distant parts desk. Westin Healthcare has a service and repairs department. Our technicians come to the home or workplace.

Future Mobility manufacturer warranty

Future Mobility Healthcare warrants the Prism Basic Back to the original purchaser for 3 years limited on the back, 90 days on the cover, and 1 year on the hardware, under normal use. Wear, misuse, and unauthorised changes sit outside that term. We handle the warranty claim with you. Ask us if an extended warranty is offered for your order.
