I had to but an overlay comforter to dissipate the heat So far, very impressed with this bed for the price

Unfortunately, after a couple of years it began to sag on my husband's side (he is 6' and 260lbs) so he was sleeping in a whole

The cover it comes with even seems to be impervious to bed bugs since my apartment building just dealt with a moderate infestation and I couldn't find a single sign of them making it through to the mattress beneath

But we love it! Higher density foam makes this 'firm' but with give and no hard spots like an innerspring mattress

After comparing and reading many reviews, this seemed like a viable option

It tends to heat up at night
