Helps a lot! Not complete solution though
Going from your basic mesh office chair to using this on top is a game changer. I can last a lot longer seating down now ( I have lower back pain/ tailbone pain etc). I feel the support in that there is no particular spot where I feel numb/in-pain...it sort of cradles you. However, this is not a complete solution because, at least for me, you do start to feel uncomfortable and have to get up after a few hours. I tried their other cushions and this is the one that worked best for me. The other thing is that despite the cloth that is supposed to keep it from moving, it does still move so you have to keep adjusting and also make sure it's well placed so it doesn't cut your circulation behind the knees. Overall, this cushion is better than not having anything on my chair. Helps with seating for longer periods of time. If that is what you need, then I can recommend.
