    • Really good

      Even though we had a problem with the mattress taking the complete form on the corners, this is an excellent mattress, I sleep like a baby everyday !

    • I love this bed!

      This bed is so comfortable I love it. I'm usually skeptical about buying mattresses without seeing them first but this bed is all that it says it is. I would highly recommend this.

    • Decent for a spare bed

      I bought this based on previous glowing reviews, but I'm quite disappointed so far. I purchased the mattress for a spare bed and I only tried to sleep on it once to see how comfortable it was. I thought that it was way too firm (even though I bought a nice fluffy mattress topper) and I became extremely warm during the night. My husband, on the other hand, thought it was comfortable. I will see how guests react to it, but I will most likely be moving this mattress to the basement as an extra bed and will be actually going to a nearby store to pick out a new spare mattress in person to replace this one.

    • Engineer

      Got our mattress free shipping was best part. as soon as we opened started to fluff and we had to wait over night for it to completely open and form its shape. was very easy to place the mattress on our bed. one thing we didnt like it doesnt say anywhere on mattress SERTA, except for the big box it came in has a SERTA sticker on it, else everywhere it says SLEEP INNOVATION. but anyways really like the mattress and hope it stays the same, with NO BUMPS< DIPS etc. and gives peaceful sleep>> Thanks and Regards, Syed Amarillo, TEXAS

    • Skeptical at first

      So I've had this for almost 2 months now and I have to say I'm still in love with this mattress. After many reviews and research I decided on this product and I am 100% satisfied with my decision. The mattress was delivered to me within 2 days, it's a wee bit heavy for one person to deal with but I managed. Also- the factory smell was minimal and nothing a little airing out and Fabreeze couldn't handle.

    • Just what I was looking for

      My husband and I have a Serta iComfort as our primary bed but due to work I had to move away and needed a bed. I was hesitant to buy one online because when it came to our iComfort, the one we wanted was not the one we chose after going to the store and laying on it. I am a side/back sleeper and my hips can't handle spring mattresses anymore. The mattress was delivered a day early and the box weighed about 85lbs. I was able to get it up stairs by myself but if you have a two story I highly recommend getting another person to help you. The mattress is vacuum sealed and compacted so when it comes out of the box it looks like a shadow of the mattress it's supposed to be but within a few hours of taking it out of the packaging it had fluffed up to it's intended 12 inches. There's a slight memory foam scent to it, but it didn't bother me. If you are sensitive to smells it might bother you but just let it air out and it'll be fine. I suggest unpacking it where it's going to go because letting it fluff and air out somewhere other than where it's going to be placed and then moving it would definitely be a pain. I slept on it the first night I had it (I refused to sleep on the floor) and the mattress just cradled me. So I've only slept on it twice but already I'm super happy with my purchase. I took the sheets off it yesterday to let it continue to air out and on the second night I had no "odor" issues at all. I don't feel the need to roll around all night long to find a comfortable spot, I wake up totally refreshed and once my body finds that comfortable spot I seem to just stay there. For the price this mattress is definitely awesome, I can tell you that my king iComfort cost 6x as much as this bed and they are both Sertas. I will probably never go back to a mattress store ever again knowing how cheap they can be gotten online. Once I've owned this a little bit longer I'll see if I can come back and update my review. Happy mattress hunting.

    • Back pain relief

      I had my reservations about memory foam mattresses but I decided to take a chance and im glad I did! I have lower back pain from an accident so waking up in the morning was an excruciating experience to say the least. Not anymore! This mattress really has reduced my back pain significantly and you'll sleep like a baby! My advice to you? Take a chance on this mattress, you'll be pleasantly surprised.

    • Pretty good

      The feel and comfort is good. The smell- not so much. There are no handles to help move/puts sheets on. The cover is of poor quality so be sure to buy a breathable mattress cover for protection. I put one on after 3 weeks of letting it air out but the foam smell still lingers. Not bad for the price and more comfortable than a regular mattress.

    • not what we thought

      we bought this mattress because of the trusted brand name, and it is a high quality, beautiful mattress. however, it is sooooo much more firm than the other reviews described. Idk, maybe it will just take some getting used to, but we have slept so awkwardly on it the past few nights. Now, we kind of dread going to bed:(

    • What are the exact densities on the three different layers of foam?

      • Hello tosil, Densities are: 2.5 in ? 3lb 2.5 in ? 2lb 7 in - 2lb. Have a great day!

    • Why can't I find this mattress on Serta's Website? Is it really made by Serta?

      • Hello Jenny Qin, this mattress is made by Serta. It is covered by a Serta warranty. Many of our manufacturers design items specifically for Overstock so they can't be viewed elsewhere. Thank you for shopping with us! A.C.

    • Can you tell me the weight of this mattress?

      • Hello rferrent1, this item weighs 85 pounds at the time of shipping. We hope this helps. Thanks for shopping with us.

    • Can this go on top of aconventional box spring?

      • Hello closetbuddhist, yes this can go on a regular box spring. Have a great day!

    • I live in a condo with a flight of stairs and have a question regarding delivery. I'm assuming that the delivery option is UPS...if overstock and other buyers can confirm their delivery experience that would be great. Does UPS allow you to schedule a delivery so that you don't have to take the entire day off work? Also will they deliver to your door or make you pick up curbside? Thanks!

      • Unfortunately nax850, the carrier of the item depends on many factors including your location and due to that fact it is not likely that you will be able to setup a delivery time. Also it depends on the carrier service and driver on weather it will be delivered curbside or to your door. It is possible to get white glove delivery after purchase. I hope this helps, thanks for shopping with us.

      • I happened to be home when UPS delivered - by chance, not appointment. The driver brought up the stairs for me. Glad he did because it is fairly heavy for a woman to lift on her own up stairs.

    • Does this type of mattress require a box spring or base to it?

      • Hello mmmmak, you do not need a box spring with this mattress. You can use a platform bed. Have a great day!

      • You do need one or the other, box spring or platform though. You can't just put it on the slats on the bed frame.

    • Ok. So if the product is faulty, or it does stay in shape or it if we are not satisfied with it what is the return policy or coverage? There has to me some sort of warranty and garantee and protection plan?

      • Hello fayruz84, this comes with a 20 year Limited Manufacturer warranty you can also purchase the 10 year service plan. If there is anything wrong with this you would be able to return it. I just got my first memory foam mattress and it is amazing! I sleep so much better now. Before I felt like anything would wake me up now I am in such a deep sleep. Have a great day!

      • The 10 year 'plan' is a weak way of charging people for doing something you should already be doing(hear that A mattress will either work or not. You should be able to return a mattress that doesn't work.
