I bought this seat cushion after having issues with my bum falling asleep from countless hours on my computer chair. Between personal and work that could amount to 10+ hours a day. I researched several of the offerings on Amazon before deciding to go with this particular seat cushion. My time and effort to research were definitely worth the effort. In the several months of ownership and near daily use, I am happy to report complete satisfaction.
No odors out of the box, which can be an issue with some memory foam products. I have had no issue with compression or loss of support, even after hours of sitting. I've moved the cushion around to a couple of different chairs in my home (hardwood kitchen, ergonomic office, squishy couch) to see how it work with different types of seating. In all cases it made sitting more comfortable, especially for any extended period. I also found it improved my posture when sitting because it helped to align my hips, and that helped to alleviate lower back pain.I would highly recommend this product.
