Heavy, bulky and can get mold
It is a bit heavy and bulky, not a easy item to carry with you. Mostly best once you put a chair and keep using without removing from there. Mine is broken into two as it got mold on it and I just wanted to wash it to get rid of the mold.

Disappointed!
This is not a memory foam at all. It is only a sponge that is far from being a memory foam. Do not recommend to buy.

Too stiff
I bought it because it had great reviews on amazon. I experienced more pain when I started using the product. It is very stiff and doesnt act anything like memory foam. Will be returning the product.

Beryl Good Product
Very good product. I m able to sit for hours continuously and very good quality as mentioned. It comes folded in half when delivered in box. After opening there was no wrinkles. One of the best product for people looking for extended sitting working hours.

A little large, good product overall.
About one week after starting to use this daily for extended hours, it's still as comfy as it was when I got it. Couldn't certainly credit the absence of back pain to this cushion, but my back isn't as sore as it was before. Be careful using this on "gaming" chairs, it barely fits on mine. Check dimensions before ordering.

Bought It for My Wife's Recovery – Now It's a Permanent Fixture in My Truck
Bought It for My Wife's Recovery – Now It's a Permanent Fixture in My Truck I originally bought this Everlasting Comfort memory foam seat cushion for my wife after her back surgery, and it delivered exactly the support and comfort she needed during recovery. The cushion is firm enough to provide real structural support while still molding to fit the body for personalized comfort—which was exactly what the doctor ordered for post-surgery sitting. Once my wife was done with her recovery and no longer needed it daily, I tried it in my truck and never looked back. It has become a permanent fixture in my seat and has made a noticeable difference on longer drives, reducing fatigue and keeping my lower back and tailbone comfortable on extended time behind the wheel. The memory foam molds quickly and holds its shape well without going flat over time, which is a common issue with cheaper cushions. Whether you're recovering from surgery, dealing with sciatica, or just spending long hours in a truck, office chair, or car seat, this cushion genuinely delivers on its comfort and support promises. A well-deserved 5 stars and one of those purchases that ended up benefiting the whole family.
