Oh my aching back! This item only made my back ache more, at first you sink in and get “fools” comfortable but side sleeper or belly sleepers be aware you get sucked in. The toppper also gets really warm at night, thought I was having a hot flash, then my husband started stripping(hahaha); tried returning but it wasn’t fitting back in the box, and there was going to be a $20 return shipping fee. Don’t waste your time or money
