What customers say about "Key Specs"
Serta Luxury Firm 400 Perfect Sleeper
  • I tried it. I sat on one of the edges, and I didn't sink. Then I did the same on a different area, still firm and nice. Then I let my body to relax and lay there and oh it feel so good!!!
  • I've had this mattress for a few weeks now and have slept on it numerous times. It's firm and supportive while still being comfortable. There is minimal movement with rolling or moving about while on it. The edges are firm and supportive, unlike some less expensive spring mattresses.
  • This bed is very comfortable and is a combination of plush and firm. The mattress itself is firm so you will not sink, but the surface is plush enough that it conforms to your body while you sleep.
  • We love our mattress. We sleep better and are not awakened by shifts when the other moves. It is soft yet firm.
  • I was a little concerned about it being too thin to be comfortable. It is fine for me, though some may prefer a softer surface, and could add a topper if they desired, or choose the thicker, plush version.
Tempur-Pedic TEMPUR-ProAdapt 12-Inch Medium Foam Mattress
  • We got firm, and firm IS DEFINITELY FIRM. But I'm definitely liking it and I KNOW my back is liking it.
  • I mean, I know it's a firm mattress (as advertised), but I've tried out firm mattresses in stores before and nothing compares to this slab of concrete. However, if you like extra, extra firm, this may be for you.
  • It contours to your body and I'm sure once I get used to it, I'll like it more.
  • Being a foam mattress, it molds to your body shape and so if you have to change position at night, that can be effortful. Same, if you want to get out of bed straight up rather than using your arms and support of the side.
  • I wanted to buy a comfortable mattress and found it.

What customers say about "Features"
Serta Luxury Firm 400 Perfect Sleeper
  • Love love this. Was almost due when we bought this. Healed most of my pregnancy body pain.
  • The edges are noticeably reinforced so that you do not sink on the sides or sink when sitting on the edge of the bed, as is common with many all-foam mattresses.
  • Also worth noting is that this mattress is very sturdy and does not shift around when moving. Overall this is a great mattress if you are looking for support and a plush surface to sleep on.
  • They claim to have a 10 year warranty but when you call you’re told if there is one stain on the mattress you will not be helped a stain has absolutely nothing to do with how horrible your mattress was made serta for 900$ I expected way more truly disappointed.
  • We bought this same mattress locally and the first couple nights were great. However, if you are a bigger person (fluffy) keep looking. It’s already sagging on my side of the bed.
Tempur-Pedic TEMPUR-ProAdapt 12-Inch Medium Foam Mattress
  • We were not pressured into purchasing a mattress and given ample time to make a decision. We are very pleased with our Tempur-Pedic mattress and already see a positive impact on our sleeping comfort.
  • Personally I like more plush mattresses but my husband who has back issues love this one so it was worth the purchase!
  • The mattress is too firm, it’s like sleeping on concrete.
  • This bed is also very heavy as in call your moving friends to give you a hand. It did not bend well to make the trip upstairs and doesn't make corners well at all. There was just no give (should have been my first clue to it's extreme hardness).
