Years we were trying to get our mattress more plush when we needed more firmness. The first night for me was a bit getting used to sleeping on a firmer mattress. This is a medium firm mattress but being a memory foam it still has that slight sink to your body and I’m a big man. My wife just lays on it and boom she is in REM sleep mode loved it on first feel. But 2nd night I’ve adjusted and I feel great! It was such a great price and far exceeded my expectations! Oh and more importantly the mattress stays cool which has been an issue in the memory foam industry. So yes gel memory foam is a big difference in that department if your looking for coolness. No sweats at night. Even if it lasts just a year it’s worth the price and I’m now sold on medium firm gel memory foam mattresses for future buys.
