Ergo flex queen
Best mattress I have slept on!! When reading the specs I thought it would be too soft for me but decided to give it a try since I have a bad back that would flare up. It’s been a few months without waking up with a stiff back and the sleep has been great. I am a side sleeper and my wife is a back sleeper. She agrees that it is a good mattress. The only con for me is when I am close or very near the edge, the edge would sink too much as if I am on a downward slope. I am close to the edge because we have a 1. 5 yo baby and he is all over the place. I won’t have this problem anymore once he is on his own bed. It is still a 5 star for me!
