Is this the perfect mattress for everyone? Probably not. Is it a great mattress? I would say yes. It appears that there is no central reference point for firm and soft and everyone has his or her own opinion about what's firm and what's soft.
Great quality, shipping, price, comfort, support, space, and anything else you vould hope for.
this one is better than those sold at $4000 to $7000 but they are definitely not $5000 worth better.
The mattress is very cooling, it is not hot or too warm at all.
