    • Great Value

      The mattress looks great and is comfortable. It's a bit firmer than another Serta foam mattress I have, but it is a very good value for the price.

    • In Love w/ My Bed!

      When considering a memory foam mattress, I was skeptical. I had been use to sleeping on a waterbed but didn't want to get another one. All I can say is my nights are just as comfortable, though there is no heat, I can always buy a heated blanket for those cold nights. I am super happy with the decision to buy the Memory Foam Mattress! I highly recommend it to anyone who enjoys a good night's sleep!

    • Jim in East Nashville

      I purchased this mattress in January and I purposefully waited for at least 90 days before writing this review. I am extremely happy with this mattress. I slept on a *********** brand mattress for 10 years before purchasing this one and it is every bit as comfortable for a fraction of the price. It did take a little longer than advertised to reach its full size with no creases than advertised (3-4 days) and for the odor to fully dissipate (7-10 days). These are not complaints, only my observations. I would highly recommend this product. Shipping was fast and everything was as expected.

    • 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.

    • Great deal - great mattress

      I read many reviews prior to purchasing this mattress, and also looked at a lot of other types. I have never owned a foam mattress before so was sort of hesitant purchasing one. My order arrived a day early, the box was in good condition (though about 85 pounds for the queen mattress box). I lugged it upstairs, followed directions and it was sleepable that evening. I noticed absolutely zero foam odor upon unpacking it, during expansion or for my first sleep - though I did notice that it "filled out" more the next morning and is taller - which is fine with me. It did take me a few minutes to sort of get used to the mattress the first night - I have never slept on anything besides a regular coil spring mattress. I was a little weirded out by the "sinking" feeling if I knelt down on the bed (while making it) - but when I laid down to sleep I sunk in very little and it lightly molded around me. I am a tosser and a turner normally so I was concerned that the foam would mold to my body and then it would feel "lumpy" if I moved around. No such thing happened. The second I moved, the foam readjusted. I will say, I do not move around anywhere NEAR as much in this bed - likely due to the fact that it's so much more comfortable. I have never really had horrible pain after sleeping but I can sometimes wake up stiff. Again, no issue with this bed. I am really very happy with it thus far! If you have never had a foam mattress before, or are not used to one, it may take you a night or a week to get used to it. For me it was just a night. As far as firm vs soft, I'm not really sure what to tell you. It is definitely firm in the sense that the foam is very dense and supportive. But it is not like you're sleeping on a rock - it is actually very comfortable. I am usually most comfortable in a level 3-4 (kind of plush) bed and I was very happy in this. I think if you're used to a really firm mattress, this might be a bit soft comparatively but I would not call it soft. I'm trying not to be confusing but without actually laying on the foam, it is hard to describe. The jist - if you're really unsure and don't want to blow 400 bucks, go lay on one at a mattress place. But I was willing to take a chance and it paid off pretty darn well. I am very happy, sleeping well, and extremely comfortable. Also noticed that when my boyfriend is over, if he gets up in the middle of the night or vice versa, there is little if any "other person movement" disturbance. Seems the foam absorbs that very well, so it's a big plus.

    • im looking for information on the size of the original package this mattress comes in. I need to get it down the basement stairs. TIA

      • Hello cfischer, unfortunately this item is out of stock. We currently do not have inventory to check, and cannot guarantee the item will be restocked. Thank you for shopping with us.

    • I recently purchased Serta 8-inch Twin Size Memory Foam mattress on Overstock. Is this the exact same version just Queen-sized? Does it come with a boxspring? Also, how does this bed compare to Comfort Dreams Select-A-Firmness 11-inch Memory Foam Queen Size mattress? Which one is better? Thanks for your help!

      • Hello Elvira T., we are still researching this and should have the answer shortly.

      • Hello Elvira T., no, it is not the same as the Serta 8-inch Twin Size Memory Foam, that one has 2 inches of memory foam and 6 inches of support foam. This mattress has 2.5 inches of premium memory foam, 2.5 inches of channel foam and 7 inches of support foam. It does not come with a box springs. The best source of feedback on the two mattresses is the reviews on the products you mention . Thank you for shopping with us.

We do not offer any direct comparisons with specific mattresses to other competing mattress companies. Have a good day!

    • 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.
