SAIREIDER Seat Cushion and Lumbar Support Pillow for Office Chair, Memory Foam Car Seat Cushions Back Support Pillows, Help Relieve Pain of Back, Lumbar, Tailbone and Sciatic Nerve（Black）

Super comfortable cushion. The back support works as promised… I like the velvet fabric it’s very soft. The bottom cushion is also great as it elevates your legs a bit and reduces pressure on your back.

I’m amazed at how comfortable this is. It’s doing my back a world of good!

I have a fully adjustable office chair that works great for me, but over the years the padding in the seat has gone flat. I have occasional sciatica issues, and require chair padding. I went through a number of Coccyx cushions. None worked for me (smaller, longer, wider, thicker, thinner, too soft, too hard, etc... sound like Goldilocks, haha ). I was about to give up and stumbled on this cushion and it works great for long day comfort, while providing coccyx support. It's wide and deep enough for my office chair. The only issue I had was that the bottom of the cushion has a grip material, but doesn't grip very well. The cushion would slide around and get into weird angles, which became uncomfortable. I had to use strips of meshed carpet grip tape to prevent the cushion from sliding around. Now it's perfect. The cushion is thick and does add some height, but my chair is adjustable, so not an issue. The cushion is firm, but soft enough to maintain comfortable support for hours, and fluffs back up when I'm not sitting on it. True memory foam. Most office chairs are 16-18" deep. Most cushions are 14-15" deep, which means you have your thighs hanging over the edge of the cushion AND the edge of the chair, which can be bad for people with sciatica issues. . If you place the cushion to the front edge of the chair, your back isn't against the back of the chair and results in slouching. Office chairs also have a bowl curvature, which requires a wider cushion to account for the curve of the chair. This was just the perfect width, depth, height, and density for the office chair. I also like that the cushion cover can be removed and washed. I haven't tried it, but I would think this could be comfortable in a car seat as well. However, I would definitely recommend the carpet tape to secure it to the seat. You don't want it sliding around while you're driving. I have been using the cushion for about a month, and hope to enjoy for several years.

So comfy!! Made my hard office chair so much more cozy for all day work

So comfortable! Instant relief for my back

This pillow is EXTREMELY stiff - very little give which makes it uncomfortable. The cover is washable, but once I washed it , it became very pilly and not as soft and was difficult to put on the pillow. Overall it did not solve my sacrolliac pain which is why I purchased it because it is so stiff. The color and size is exactly as described.

I injured my tailbone plus I have chronic sciatica. I got this because with tailbone injury I couldn't sit on the local bus to go get groceries, ect. It is awsome! Perfect thickness and memory foam didn't get thin after sitting on. I couldn't afford the more expensive ones and honestly was nervous that this one at a lower price might not be good. I was pleased and I really like it! It has a washable cover and a happy little handle. I am so happy I can use this on bus or even at home.

If you are experiencing sciatica pain, the seat cushion may not be the best for you. The seat gives a lot of height, which causes the legs to drop and increase pressure on the nerves, however the lumbar support helped with the sciatica. If you are experiencing general LB pain or tailbone pain however, both the seat and lumbar support works great!
