    I suffer from fibromyalgia which often leaves me in a great deal of pain. In the past I have purchased more expensive mattresses to find them in worse condition as well as providing no relief. In the past I purchased the twin size mattress which we still have and instantly fell in love. The softness and the comfort is AMAZING! Especially for the price you can't beat it! Now, if your expecting to get a $10,000 mattress for this price or top of the line try else where this is NOT the mattress for you but if your expecting to get a fairly decent mattress that is comfortable for a great price than look no further! Most people including myself seem amazed at how the mattress unfolds out of the box and starts to slowly rise to it's proper position. It does take time to fully erect to it's correct size I believe it's 48 hrs but it usually rises faster than that. Now if you purchase you MUST be careful when taking it out of the box and removing the tape as not to cut the mattress. The only complaint I have is that I ordered it online @ walmart and the box arrived pretty beat up! Other than that LOVE LOVE LOVE this mattress! Gr8 buy for the price!

    I have a day bed frame and was looking for comfortable mattresses to use on them. I read the reviews and was impressed. It is true these mattresses are so comfortable. My day bed has a pop-up trundle bed that folds under it. The mattresses were bought for my guest room so that I can use it as a studio couch in my office on a daily basis and when I have guests it opens into a king sized bed. I had to test them out to make sure they were good enough for my guest, and they are. I slept like a baby. Thanks Walmart Rumpoint

    I was very skeptical even with the good reviews but we ordered this to go in my daughter's (5 yr old) room for her daybed. It's not too low and not too high of a mattress and is just right. So far my mom and my husband have slept in her bed, so it holds up for adults too. Couldn't be more thrilled that we paid $150 for a decent new mattress. It's surprising how it inflates IMMEDIATELY after you take it out of the box and wrapping. Who knew, this would work out like it did...we are way beyond happy with this purchase, so "don't sleep on this savings"! :-)

    I purchased this mattress after buying a new bed. I was nervous about it, thinking that I would hate it. Turns out, I loved it! It quickly took shape after I took it out of the box and unrolled it, and I slept on it that same night with no problems! You can't even tell that it came from a box. I do recommend getting a mattress pad, though, because sometimes if you turn over, you can feel the springs moving.

    I got this mattress yesterday and today was the first time i slept on it.So comfortable and nice. Mattress comes in a package .when you unpack it-let the air out and within 30min the mattress was its full size.I would recommend to leave it "breath"for an hour.then it is all good. Delivery was prompt-even 3 days than expected. I hope it will stay that great throught time.

    Customer has been confirmed to have purchased the item from Walmart.

    The bed is really easy to move around since it is compacted into such a small box. It inflated very quickly. As soon as I took it out of the box and unrolled it, it immediately started expanding to its original size. The bed is very comfortable and there is no weird smell or anything like that. It's an excellent purchase considering how inexpensive the bed is. I'm extremely satisfied with the bed. "Bed in a box" sounded pretty sketchy to me but its totally fine after you take it out and let it expand.

    Day 2.. So far so good! Mattress expanded in 10 min or so, it reached more that the size I ordered (8"), see pictures. Mattress is firm but comfortable, design on it looks good. I'll make an update 6 months later. Got questions?, ask me!

    • A. The box should fit into the backseat just fine. Wal-Mart loaded it into my car for me and I unloaded it at home. The box is a bit heavy, but I managed it and I'm a 5'-1" woman.

    • A. Not unless you can open your car door enough to accommodate a box the size of 62" long and about 40" wide. My Camry will not take that - the 40" is the problem - open your car door and measure but don't forget the back seat will lift it up - doubt you can put in a 40" square box into the back seat. I'd say back end of a SUV, van, wagon or pick up. Don't forget if you take out of the box or it opens up full of air - and doubt you could get it out of the car once it opened.

    • A. By "in a box" means it comes in a heavy duty cardboard box. Once the mattress is removed from the box it is vacuum packed in a clear plastic bag. The mattress is compressed very flat, in the bag, the folded in half, then rolled up. It was quite a surprising to see a queen mattress packed like this but after a couple of days of being opened it is a 60 by 80 inch mattress!!!

    • A. Mine is on 2x2 wood slats and it is just fine. It could also be placed on a traditional solid platform (plywood, etc.) "In a box" refers to how it is shipped. The mattress is folded/rolled then vacuum sealed in plastic to keep it in a small box. You won't believe a mattress is in the box when you receive it!

I bought a full size and the box measured 39"x16"x16" and weighed about 60lbs. so you could easily get this into a small car , not on the roof .

    • A. This matress is a real matress like one you would buy out of a matress store. I bought it because it was amazing that a matress could be packed inside a box and then inflate once taken out. The instructions indicate that the matress will be in full form in 24 hours but it was much sooner, like and hour or so. It could sit on any surface you choose.

    • A. No way! Have you ever used that spray foam insulation that comes in an aerosol can? I think this bed is made out of that stuff. You spray it out of the can and it expands and sticks to everything and then hardens. To get this mattress back in the box would be like trying to get that foam insulation back in the can. LOL
