Review on Optimized XL Gel Seat Cushion for Office Chair/Car/Wheelchair/Long Sitting | Breathable Chair Pad with Cooling Gel | Thick Cushions for Pressure Sores, Tailbone, Back, and Sciatica Pain Relief by Melanie Lujan

This cushion definitely makes sitting on hard chairs more comfortable. For me it is better than a standard foam pillow. The zip case is flimsy and I feel like it won't hold up with frequent use. The pillow is surprisingly heavy, which is good. Overall I like this pillow for what it is, a fairly inexpensive product. Although I would have liked it to be bigger. I want it to be at least as big as they say it is. No, that is not so. The item description says it is 17 x 17 x 1.7 inches. The TRUE measurements I checked with a tape measure are 16 x 16 x 1.5 inches. I'm not sure why the company exaggerates the size. Maybe they measure the thin protrusion of the lid. This makes these companies difficult to trust when they give buyers false information. I will say that the company delivered it incredibly fast! I recommend this to people looking for something that makes sitting more comfortable. If you have severe seating issues, this may not be for you.
