Description
The Geo-Matrix Hybrid cushion is Blake Medical's 3.5 inch (8.9 cm) foam-and-gel wheelchair cushion for moderate postural support and skin protection. Westin Healthcare fits it in Brampton and across the Greater Toronto Area after a seating check on the chair. Ontario lists the Hybrid seating line as SESG00030.
This is the standard Hybrid height with the GH size code. It is not the 2.5 inch Geo-Matrix Hybrid Low-Profile, and it is not the all-gel Silver or Bronze.
Who this cushion is for
The Geo-Matrix Hybrid cushion is a wheelchair cushion Canada families usually call us about when a seating therapist wants a gel wheelchair cushion with a gentle contour, not an air bladder and not a two-layer comfort pad. Blake Medical indicates the Hybrid for people at moderate risk of skin breakdown and for help with stage 1-2 pressure injuries, and for vibration control on a daily chair.
A seating therapist should confirm the size and the model. This page does not give clinical positioning advice. If you have questions about wounds, posture, or transfers, ask the therapist who assessed you, or call us and we will book that conversation.
Fit and size
A wheelchair cushion should match the wheelchair seat, not a clothing size. Measure the seat width and seat depth on the chair. Blake's Hybrid manual says the cushion width should match the seat, may sit up to 1 inch (2.5 cm) wider against the arm supports, and the depth may run about 1 inch past the seat. The Blake logo faces the front left.
Use Choose Width and Choose Depth for the seat size. Blake's standard Hybrid sizes run 16 by 16 through 22 by 22 inches (41 by 41 through 56 by 56 cm). The product code is GH then width and depth, for example GH1818. Custom dimensions are available from Blake. We check the hook-and-loop hold-down and the cover orientation at setup.
- Standard height 3.5 in (8.9 cm)
- Weight capacity 275 lb (125 kg)
- Closed-cell foam base, dual high-density foam core, cascading Pillow Top gel
Gel, foam, and care
The Geo-Matrix Hybrid is a gel wheelchair cushion with a foam core. A closed-cell foam base and a firm sacral shelf sit under a cascading Pillow Top gel layer that Blake says reduces pressure behind the knees. The gel is a dry-polymer solid. It does not inflate and it does not leak like a fluid pouch.
Each cushion ships with a soft-touch outer incontinence-proof cover and an inner wipeable moisture-proof cover. Both covers machine wash to 60 C. Do not wring them. Lay them flat to dry. Do not use bleach. Do not wet the foam. Wipe the gel, then air-dry the cushion out of direct sun. We show you the cover zippers when we set it up.
Geo-Matrix Hybrid cushion specifications
These figures are from Blake Medical's current Hybrid card. The specification tab holds the stored values.

Hybrid, Hybrid Low-Profile, or Platinum
Stay here if you want the standard 3.5 inch Geo-Matrix Hybrid cushion and the 275 lb rating. The Geo-Matrix Hybrid Low-Profile Cushion is the same foam-and-gel build 1 inch shorter (2.5 in) at 250 lb (113 kg), for a lower seat-to-floor height. The Geo-Matrix Platinum Cushion keeps a foam core and adds a full Blue gel base at 3.75 in for people Blake describes as at higher skin risk. The Geo-Matrix Silver Gel Cushion is three layers of gel and no foam, at 2.75 in and 200 lb (91 kg).
Air, foam, and gel are different jobs. A seating therapist should pick the medium. We will not choose it from a web form.
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.

Westin's own team delivers and sets up this cushion across Brampton and the Greater Toronto Area. We bring it in, check the size on the chair, and show you the covers and the hook-and-loop hold-down before we leave.

Frequently asked questions
What Size Wheelchair Cushion Do I Need?
The Geo-Matrix Hybrid cushion should match the wheelchair seat width and depth. Measure the seat, then use Choose Width and Choose Depth. Blake's standard Hybrid sizes run 16 by 16 through 22 by 22 inches, for example GH1818 for 18 by 18.
How Do I Choose Between Gel, Foam, And Air Cushions?
The Geo-Matrix Hybrid cushion is a gel wheelchair cushion on a foam core: no inflation, no fluid pouch. Foam-only cushions are a milder contour. Air cushions use cells you set with a pump. Ask the seating therapist which medium fits the assessment.
Does ADP Cover Wheelchair Cushions?
Ontario's Assistive Devices Program can help with a wheelchair cushion or back support after an ADP-registered therapist assessment, when the seating is required with an eligible mobility device. Eligibility depends on the person and the device. Call (905) 451-7743 or use the funding page before you buy.
Is The Hybrid The Same As The Hybrid Low-Profile?
The Geo-Matrix Hybrid cushion is 3.5 inches tall and rated 275 lb (125 kg). The Geo-Matrix Hybrid Low-Profile is the same foam-and-gel construction 1 inch shorter (2.5 in) and rated 250 lb (113 kg). They are separate Blake models.
How Do I Clean A Geo-Matrix Hybrid Cushion?
The Geo-Matrix Hybrid cushion covers machine wash to 60 C. Do not wring them. Lay them flat. Do not use bleach. Do not wet the foam core. Wipe the gel and air-dry the cushion out of direct sun.
What Does SESG00030 Mean?
SESG00030 is the Ontario seating code printed with the Geo-Matrix Hybrid line. The Hybrid Low-Profile uses the same family code. Ask us which model and size are on your order before any funding paperwork starts.
What Is The Weight Capacity Of The Geo-Matrix Hybrid?
The Geo-Matrix Hybrid cushion is rated 275 lb (125 kg) on Blake Medical's current card. Stay at or under that rating for the size you order.
Does The Hybrid Need Daily Inflation?
The Geo-Matrix Hybrid cushion does not inflate. The gel is a dry-polymer solid on a foam core. There is no daily calibration step like an air cushion.
What Comes With The Geo-Matrix Hybrid Cushion?
The Geo-Matrix Hybrid cushion is ordered as the foam-and-gel pad plus the inner moisture-proof cover and the outer incontinence-proof cover for the size you pick. Westin Healthcare delivers and sets it up across Brampton and the GTA.
