AliMed T-Gel Checkerboard Wheelchair Cushion Excellent for applications that require minimal thickness. Low-profile T-Gel allows use on any sitting surface and is made of a soft, rubber-like elastomer gel that mimics skin-protecting fatty tissue, moving with the skin to minimize the effects of friction and shear while reducing the formation of pressure injuries. Independent checkerboard cells offer better reaction to patient movement and greater air circulation for maximum shear relief. Cover options include Black Stretch Polyester Knit or durable Blue Ripstop Nylon that resists incontinence and stops punctures from becoming tears. 5/8"H 5-1/2 lbs. Gel will not leak or dry out if accidentally punctured or cut
