Our take on the SitCushion X-Large Car Seat Cushion

The SitCushion X-Large is a memory foam seat cushion sized 20 x 18 inches, about 3 inches thick, meant to add height and padding to a car seat or desk chair. It has an anti-slip rubber base, a removable washable cover and a built-in carrying handle. At $25.67 at eBay as of November 5, 2026, it is the only new price listed, so there is no recent range to compare against.

Questions and answers

Is $25.67 a good price for this cushion?
It is the only new price listed as of November 5, 2026, so there is nothing to compare it against. At under $26 for a memory foam cushion with a washable cover, it sits in the low end of what cushions this size usually cost.
Will it fit my car seat?
At 20 x 18 inches it is wider than many standard cushions, so it suits full-size car, SUV and truck seats. Measure your seat base first; on a narrow bucket seat it may overhang.
How much height does it add?
About 3 inches. That helps shorter drivers see over the wheel and softens a hard seat, but taller drivers may find it lifts them too close to the roof.
Can I wash the cover?
Yes. The cover is removable and washable; follow the care label and air-dry the memory foam core rather than washing it.
Does it stay in place?
It relies on an anti-slip rubber base rather than straps. That holds well on most seats, but it can shift on smooth leather during hard braking.
What is in the box?
One black X-Large cushion, about 3.31 lb, with the cover fitted. Nothing else is included.
Where is the SitCushion X-Large Car Seat Cushion cheapest?
At eBay, for $25.67, as of our latest check.
