  • Love this mattress

    We love this mattress no more back pain in the morning. We can't feel the dogs or each other move around. Its perfect for us. Ordered it on a Tuesday had it by Thursday and Friday woke up well rested. For the price and being a king can't beat it.

  • Makes me late for work ;)

    I was a bit skeptical buying a mattress online, but I gave it a shot. My very first night on this mattress made me late for work the next morning. I really didnt wanna get out of bed. After sleeping on my old spring mattress for years, this is a breath of fresh air. I let it air out for 3 or 4 hours, and slept on it the same night it was delivered. The smell didnt bother me at all. I recommend this mattress to anyone who wants a great nights rest. Its been one year and it still makes me late for work!!

    • Please tell us about the quality of the product. Still 5 stars after one year

  • Great bed

    I was nervous about buying a bed online since you don't get to see the product before you buy it. But after reading many reviews and actually going to a mattress store, we decided to buy it. This bed is absolutely amazing. I have had back issues for most of my life, and after sleeping on this bed the pain has been greatly reduced. We have both noticed that not only is it easier to wake up in the mornings, we feel more rested and energized. One thing I will say though is that if you have never been on a memory foam bed, go to a mattress store to try one out first. We tried the Tempurpedic and could not tell a difference between that and the Serta, so don't be afraid if it's not the same brand. Memory foam is not for everyone, so be sure you like it before you buy one. If you know you do, then you will not regret this purchase. By the way, memory foam beds are supposed to last 20-40 years. (Much longer than a spring bed.)

  • Perfect for Me

    This mattress is the best thing that has ever happened to my sleep life! After initially receiving the mattress within a week after my order was processed, the UPS guy brought the human sized box into my home for me; I opened the box, removed the plastic and the giant mattress expanded in seconds! I waited 36 hours before using the bed-even though it said 72 hours-I just couldn't hold back. That night I have never slept more sound in my life! The second night I slept in it, I awoke in the same exact position I fell asleep in. Each and every day after this I can wake up in the morning with ease as I feel completely refreshed and re-energized for the next day. I have had this product for about a month now and I can't stop bragging about it. Any other mattress from anywhere else would have been incomparable to the value I received with this purchase. The mattress itself is fairly firm which is obvious as it is only 8 inches thick but the foam makes it fell soft to the touch when you first lay down and then conforms to mold with firmness for the rest of your body. I recommend purchasing a down pillow or a memory pillow as it seemed to bother my neck with a standard pillow. Be sure to note that this product cannot be returned after removing the plastic wrapping!

  • Serta Memory Foam Mattress

    This is a really good mattress. It is firm, but still really comfortable. I slept on a futon for years and that mattress was finally killing my back so I decided it was time for something new. This mattress hasnt completely erased my back pain, but it has been greatly reduced. I can actually move in the morning now. It has also seems to have reduced my boyfriends snoring and I can get to sleep at night next to him. You can't beat the price on this thing. It is worth much more than what Overstock is selling it for. Definitely worth buying!

  • I am completly sold on memory foam

    I am 7 months pregnant and could not sleep comfortably any more on our queen pillowtop. We looked into all different mattress types and agreed that memory foam was the way to go. I had gone to a mattress store and tried out this same mattress and liked it, however Overstock was selling it for less. It arrived in 4 days and after we opened it, it immediatly flattened out, I would say every crease was gone with in 4 hours. We waited one day to sleep on it because my husband was worried about the smell (I never smelled anything, but my nose has been plugged up with a cold). For people questioning whether or not it is really a Serta, the answer to this is it is and it isn't. The company who actually makes it is Sleep Innovations, however then other brands rebrand their products, like Serta. Kohls actually sells their pillows and mattress toppers under a "Home Classic" name, and Serta sells the mattresses under their name. We actually bought 2 memory foam pillows at Kohls the same weekend not realizing they were Sleep Innovations as well. Regardless, it was one of the best nights of sleep that I have had in forever. I heard that memory foam took a little getting used to, but I had no problems sleeping the first night. My only slight regret is that I realized they sell a 10'' and 12'' model after I bought this one, had I known I probably would have gottan a 10'' instead of the 8'' because it would then come up a little higher off our platform bedframe. Other than that, I am extremly pleased with the purchase, i love having the extra king size space, the matress is exactly as drescribed and I am pleasntly surprised not to have had any kind of "adjustment" period.

  • The answer to my aching back

    The only problem I have with this mattress is that I cannot sleep comfortably anywhere else! It is the most comfortable mattress I have ever slept on and for the money - it's an incredible bargain. I paid over $2,000 for a queen-sized mattress that was similar to a sleep number bed. This foam mattress beats it by miles and miles!

  • Great Purchase!!!

    I share a bed with two dogs that chage positions all night long. With this mattress, I don't feel a thing! It's so comfortable and so easy to lift. So much better than a traditional mattress.
