    • Great mattress at an even better price
      Verified Purchase

      I was a bit nervous about ordering a mattress online. We needed a twin mattress for a new daybed, and didn't want to spend too much since it will have minimal use as a guest bed. I contacted a few local mattress companies and to get a mattress thicker than 6 or 7 inches costed more than expected, and I didn't want to sacrifice mattress thickness just to save a few bucks. So, I decided to look on Overstock. I viewed several twin mattress reviews here and decided on this one. When it arrived, my husband was a bit puzzled since it was in a smaller box. But after opening it, the mattress immediately opened and filled out after starting to remove the wrapping. After 24 hours, it had only expanded to about 7 inches height. But after 3 days, it fully expanded. The mattress is soft, but not too soft, and has a nice level of firmness to it. I already had a mattress pad and cover, so I added it, but this mattress doesn't need it. I just like the added thickness, as the mattress pad and cover adds about 2 more inches. I'm ecstatic that I took a gamble on ordering a mattress online, I saved on the price of the mattress and delivery costs by doing so.

      Bought this mattress along with Prlage 9-inch Twin-size Smart Box Spring Mattress Foundation for my mother to sleep on when she visits. It looks and feels thick enough and firm enough to handle an adult sleeping on it without smushing down to the foundation. Granted, no one has slept on it yet, but I laid on it for a few hours and it felt great. It is not a flippable mattress, however, FYI. Would buy another if we ever needed one.

    • Comfortable sleeping
      Verified Purchase

      This mattress arrived quickly and upon opening the shrink wrap, it took just a few hours to get to full size. The mattress fits comfortable on my daughter's Captain bed and is very stable. I like the fact that it does not transfer weight easily so when I take her to bed some nights she doesn't even realize I've left. Very good for a preschooler, not a lot of bounce Donna fun jumping on the bed. :-) I think this mattress will last a while. I would consider this mattress in a different size, full for my older daughter's bed in the future!

    • Good quality for the price
      Verified Purchase

      I bought these for bunk beds. They are on a bunkie board and are nice and stout. The only reason I didn't give five stars is because the "plush" in the description isn't really true. It is soft in the top layer but the mattress itself is rather firm. It doesn't give you a "sink-in" feel that you'd expect when you think plush. Now, that being said, they are pretty good quality considering price. Theye were literally like 2 inches thick in the packaging but after about 24 hours were fully expanded. These were for my kids and they sleep fine on them. For an adult expecting a plush mattress, I'd look elsewhere. If I had ordered it for my bed, not my kids, I'd have been disappointed in how firm it ended up being.

      Was surprised when a small box showed up at my door when I was expecting a huge one. This mattress packaging is very cool. The coils are tightly compressed and then it is rolled into a small rectangular box. When you cut open the plastic bag it magically springs into its normal shape. Overall we are happy with the quality of the mattress - it is comfortable and a good value.

      Bought for our 150lb young man. If you like springs and the push back they give, instead of sinking into a foam mattress, then this mattress is for you! It's comfortable, with the plushiness on the top, encased in softness. Purchase a waterproof mattress encasement and you'll be "good to go."

    • Incredible
      Verified Purchase

      I was a bit hesitant to order a mattress online without seeing it in person and testing it out, but a friend had recommended Overstock after he had an amazing experience with his mattress and especially the price! After reading over only a few different mattresses and reviews, I was SOLD on this one simply based on all of the great feedback. When it arrived it opened up to the full 8" within the first 5 minutes. It was very impressive and kind of fun to watch it open from such a small, compressed packaging. It's extremely comfortable and I would recommend this brand to anyone looking for a good mattress!

      Verified Purchase

      The mattress came vacuum sealed in relatively small box to hold a mattress, but once you break the plastic it grows to mattress size. My niece said it slept well, was very comfortable. It looks good, is quite heavy when trying to square the corners (nurse) when making the bed. Pleased with purchase, good value for the dollar.

      Good for the price. I bought it for my youngest grandson (3 years old) and it works just fine for him. I would say if you're an adult or if your buying this for an older child you may want to pay a little more for a mattress.
