Review: Comfortable, Supportive, and a Game-Changer for Long Sitting Sessions - I’ve tried a few seat cushions over the years, and this one immediately stood out for its perfect balance of comfort, support, and versatility. From the first time I sat on it, I could feel the difference. My tailbone, lower back, and even hips felt noticeably more supported, which is a relief for long hours at a desk or in the car. The memory foam is firm yet cushy, providing targeted support without feeling too hard or too soft. The ergonomic cutout is thoughtfully designed to reduce pressure on the tailbone and promote better posture, and I’ve noticed less fatigue and discomfort after hours of sitting. The removable microfiber cover is another highlight. It’s soft, breathable, and easy to clean, which keeps the cushion feeling fresh even with daily use. The cushion’s size fits most office chairs, computer chairs, and car seats, making it incredibly versatile for home, work, or travel. Durability is impressive as well. Unlike thinner or cheap foam cushions that flatten quickly, this one maintains its shape and support over time. I can tell it will last for years while continuing to provide relief for general lower back discomfort. If you spend long periods sitting and want genuine relief, better posture, and comfort, this ComfySure Memory Foam Seat Cushion is an excellent choice. It transforms an ordinary chair into a supportive, comfortable seat and has quickly become an essential part of my daily routine.
Review: Floats tailbone,Firm Support,Never goes Flat! - After comparing prices, features and reviews, This office chair cushion is a better value compared to others, plus it’s more of a firm support that does not totally go flat when you sit on it, I am not a small light weight person at all, and this cushion hold up, it is comfy yet firm and it holds its shape even for long hours in an office chair. Great pain relief for the tailbone if you position the cushion correctly with the opening to the back, that opening keeps pressure off the tailbone area and floats the coccyx, to prevent injury and pain from sitting for long periods. I also like the color, it is more of a royal blue not a navy blue as shown in the photos, color not what I expected but the color has since grown on me, it looks nice in my white leather office chair because I have other blue furniture in the room so it works okay with my white and blue ranch house decor.

### ⭐⭐⭐⭐ Love this but wish it was firmer.
*by T***. on August 8, 2018*

Love this cushion. I bought this to boost me up in the car so I can see better over the steering wheel. Now I sit high enough to use the sun visor and keep the sun out of my eyes. It's comfortable and it does relieve pressure on my lumbar. I wish it was a little firmer so it would last longer. But it is worth the money and I will buy again.
