The mattress is ok so far; I think we had higher expectations about it's comfort from all the publicity/hype. The mattress is warm after laying on it a few hours; no different than other mattresses when we were told it wouldn't do that. Haven't decided if we will be keeping it or not yet.
Not sure yet. Both husband and I feel like we roll to the middle and I feel like I get hotter at night. Still unsure. Comfy when I lay on side or belly.
