  • Still comfy months later

    It's been months (6?) since I purchased this mattress. I have to say it's held up wonderfully. It's my first memory foam purchase and I was hesitant to buy such a cheap mattress because I was worried about the foam collapsing after too much use (especially buying online). I'm happy to report this has not been the case. The mattress is still like new with no indents/sinking in problems. My husband says it is quite firm and he has back problems. He reports these have improved since purchasing this mattress. I believe I sleep better on this mattress as well. It's very comfortable & I love the way it forms to your body. We had a pillow top one which we ditched into the garage after we bought this one. We thought we'd bring it back out if this one didn't work but - there is NO WAY I'd ever go back to a regular mattress. This is a good mattress & I would recommend it.

  • 2 years

    I think i wrote a review after just buying this bed when I loved it. It has been about 2 years of owning and the bed is still in good shape. We are looking into buying a new bed because this bed is just so hard. At first i was loving it but now for some reason this one feels like a rock. I wake up with crazy back and neck pain. For the price it is definitely a good starter bed and a good price for what it is. If you are looking for extreme comfort and no back pain I'd suggest something else.

  • Very comfy

    My 9 years old son slept on it last night for the first time and when I asked him this morning how it was. He said "it was very comfortable, felt like I was sleeping on a cloud".

  • great, except center is more dense than sides

    We already bought the queen size of this and we were very happy. This cal-king one has big difference in density between center and sides. In center is it very firm and on sides it is soft. We tried both spring box and platform bed and it is the same.

  • Fantastic Bed, Fantastic Experience!

    First, I really appreciate that other people left reviews here...it really made me feel comfortable making a purchase like this (online, without testing it) and in deciding on this specific memory-foam mattress. I purchased this mattress at Overstock on a Friday, got free shipping (with the O Club Membership---which immediately pays for itself) and it arrived the next Tuesday! **** You may want to sign up on Overstock's Site as a regular member before your purchase, as they send out 10% e-mail coupons **** As other reviewers stated, it's hard to believe that a California-sized king bed can come in a box that's roughly four feet high by two feet wide (87 pounds), but it does..... and it's perfectly fine! The bed comes in a plastic bag that is surrounded by a stronger threaded plastic outer layer (which keeps it compressed), and then of course the shipping box. You just simply take the bed out of the box, place the wrapped bed on your frame or box springs, carefully cut the outer layer off with scissors, and then watch your bed grow to full size! Remove the lighter inner plastic cover and you're ready to go. My wife has a very good sense of smell and said she could barely detect an odor from the bed. Once you let the bed stretch a little (5 minutes), the instructions say that it's perfectly O.K. to lay on the bed and sleep on it immediately, which we did. We kept our existing bed springs and just replaced our mattress. This 8" Serta exactly replaces the length and width of the Cal King mattress we had and we use regular Cal King sheets with it. It also is a full 8" high, as described. The comfort of this bed is fabulous. Because it's a memory foam bed, it adjusts to your size and weight and then sort of molds you into it. It is a bit firm, in the sense that once you sink in it stops moving. As others have noted, because this mattress is probably unlike anything else you've ever slept on, it's just feels different at first and it takes a short while to adjust to this feel. What feels like firm at first feels great a couple of days into sleepng on it and the discomfort and pain we had been feeling from our old spring mattress just disappeared!!! The only way I can describe it is that it feels like there's nothing around you, as if you were laying directly on the ground, but yet it's super comfortable ---- i.e. natural!!! A great feel and experience! By the way, one concern we had was that it might heat up with our body temps and be too warm--- we've found just the opposite and find both the comfort and the coolness to be excellent. If you're a light sleeper and your partner comes to bed later, you'll love this bed. I'm a night person and my wife says she doesn't ever wake up now / know that I came in later!!!! We joked there's not enough hours in the day to enjoy our bed and are both loving it. Again, like others mentioned, you can always add an affordable feather top if you need more of the spring-like cushion that a traditional mattress provides....we're happy with the way it is and are sleeping better than we ever have! Finally, I just used our O Rewards (credit, after joining the club, from your purchases toward future purchases) toward an area rug with, of course a 10% off coupon.... and the product and delivery were once again, perfect. I am a customer who expects very good service and have been totally thrilled with the e-mail communications, tracking numbers, and everything that Overstock has provided us in our experiences so far! Happy shopping to all of you and thanks to Overstock for the value and the service--- we will definitely be shopping with them again in the near future!!!

  • Great mattress

    I really struggled about buying a mattress online, but I bit the bullet and bought it anyway. I have been sleeping on a waterbed for the last 27 years and was concerned about sleeping on a regular mattress. I chose the memory foam for the comfort of conforming to my body. I have not been disappointed at all. I have slept extremely well since the first night. I was concerned because it came in such a small box, but the minute you let air in it "grows". The other reviews stated there would be an odor, but I did not experience any odor at all. The mattress fits in my waterbed frame well. The only negative I can say is that I wish I had gotten the 12" instead of the 8". I fills the frame but is slightly lower than the side rails. I love this mattress. I would recommend it to everyone, as a matter of fact I have recommended it to several people. I look forward to many restful nights!

  • Memory foam was just as advertised.

    I have suffered with low back pain for years. The memory foam is very comfortable and has sure helped my pain.

  • Great product!

    We've bought 4 of these to date - one for each RV, and 2 beds in the house - after 2 previous back surgeries, never slept better! NO issues of any kind with shipment, delivery, unpacking, or installation - all as advertised, and better!

  • Best Purchase Made Online

    This mattress was a great buy. It was worth the price. I don't wake up with back pain anymore, but I also have a magnetic mattress pad on top of it as well. It's so comfortable. My old mattress would sag and I would roll into my husband but that no longer happens. The shipping was quick as well. It came in a big box. You have to remove your old mattress first and then unroll it on top of the bed frame. The California King size was perfect. It had a smell but once I put the magnetic mattress pad and sheets on top I could not smell it. If you sign up for Omail you get a 10% discount. That discount saves you a lot of money. I really really love this mattress! My husband does too. It was the best money I spent and a great deal. I would buy another one and tell everyone about this mattress from Overstock.com. FYI, Serta is made my Sleep Innovations.
