Serweet 12 Inch Full Size Hybrid Mattress

Update: It's too soft. I gave it a few weeks based on my chiropractors reccomendation. But it's just too soft. It's otherwise a good mattress. For me - I wake up with an ache in my lower back and a tightness that wasn't there before. It's just outside the return window, so I'm not sure what I'm going to do with it. ---- Update: I'm surprised to be saying this but so far it's comfortable. If I sit in it or stick my hand on it ,it feels too mushy... Like an air mattress without enough air. But sleeping on it I feel supported and supported. I sleep well. ----- I'll definitely do an update after a few days. Right now, it just feels mushy. Like - the opposite of medium firm. This will be my first night on it.
