Great product for the price! ### ⭐⭐⭐⭐ Decent for the price, mild comfortability, not good for longevity though *by A***S on June 29, 2026* I bought a different brand and shape which ended up being super thick and hard, out of nowhere midday it would flatten out completely. I bought this one to replace the other one, to be honest...while it doesn't flatten as quickly as the other one, it still does flatten. I seem to have more support when I pull it all the way to front and sit on it mostly using my thighs. It is soft, mildly firm, looks the same as it does in the picture. It alleviates some pain, but after about two hours I have to walk around to let it unflatten itself. It worked better when I stacked the two of them but it is not realistic to have both at work. I may try to turn it around as another comment suggested, not everyone is made the same so it might work. Either way, not bad for the money but would like something that doesn't flatten so quickly. ## Frequently Bought Together - Benazcap X Large Memory Seat Cushion for Office Chair Ergonomic Cushions Pad Pillow for Pressure Relief Sciatica & Pain Relief Memory Foam for Long Sitting for Gaming Chair and Car Seat Black - QUTOOL Lumbar Support Pillow for Office Chair, Back Support Pillow for Car, Office Supplies, Chair Cushions, Back Pain Relief Improve Posture, Mesh Cover Double Adjustable Straps - Cushion Lab Patented Pressure Relief Seat Cushion for Long Sitting Hours on Office & Home Chair - Extra-Dense Memory Foam for Soft Support.
