After reading so many reviews and researching, I finally just went ahead and purchased this mattress in July 2020. Here it is November and I must say I am very happy.  I purchased the king size and being a 65 female it is very heavy but I was able to unpack it and put it on top of my box spring.  I agree with a previous review that this mattress is not for sitting on the side. It is very firmhard but for me being a plus size person with arthritis, it gives me great support!  If you’re looking for a soft plush mattress, this is NOT the one. I also purchased a pillow top mattress cover which made my sleeping comfort even better. Will be purchasing a full size mattress like this in a few months. If you’re looking for a firm mattress that supports your pressure points and eases pain if you have arthritis, I recommend this mattress.
