Bought the bed sight unseen, never even took the time to see what a brand name foam bed would feel like, so I really don't know how close this one comes to the 3-4K type. Bed came promptly as do all my purchases from Overstock.com so no little surprise there, just another happy purchase from this company. Bed dimensions are slightly smaller than listed, but not enough variance to complain about. The chemical smell people gripe about wasn't too obtrusive, and dissipated in the most positive sense of the word. The bed is a little firmer than we had wanted, but after a few weeks it seems to be softening (or we are just getting used to it). One comment that I must agree with is that we can not get the mattress to maintain the trade mark "hand print" that we see advertised on the major brands product, but as I mentioned before we have never really tested any of the name brand beds. We live in Northern Arizona where we just went through two weeks of record heat (sleeping in our new bed), and we did not notice the bed being uncomfortably warm as others have complained about. Another common gripe that we had read in reviews prior to purchasing was the notion that the bed starts to "sag" in spots where people sleep, and although I am 6'2" and 240 lbs (not overweight at all) and my wife is 5'10" 135 lbs (I better note she isn't over weight at all, if I want to continue sleeping in the bed), we have not noticed any change in the beds resilience. Now keep in mind we have only had the bed a few weeks so I can't comment on the long term qualities of the bed but for now we are pleased.
