    Mattress is extremely comfortable. My mom sleeps on it when she visits and said it is as comfortable as her sleep number bed which she paid $3000 for. I have arthiritis, sleep on it nightly, and awaken in no pain. Great product!!

    Customer review by GrillGirl1002

    5.0 stars by GrillGirl1002

    I bought a twin size for my guest room. I already had the frame $59 from Walmart, no box spring needed. I had it shipped to my local Walmart (ship to store) for free shipping. The total for the mattress was $200. It came in a box 40" x 17" x 17" and weighed about 45 lbs. It was easy to move it from the cart to the car trunk, no lifting, just some maneuvering, and I had to bungie cord the trunk shut. I dropped (nothing can break!) the box out of the trunk unto the ground and used a dolly to bring it into the house. The reason I am telling you all of this is because I had questions whether I could pick it up at the store or pay for shipping to my house. Everything was EASY!! Once I got it in the house, I removed the box (do not use a box cutter or you will ruin the mattress) by undoing the box seam down the side. Dragged the rolled up mattress to the bedroom and lifted it onto the bed frame, cut the tape holding the rolled up mattress, unfolded it, and used scissors to cut the plastic and you could hear WHOOOSSH when the air rushed in. Within about 2 mins it was filled out and during the next 24 hours it REALLY filled out. It is so comfortable! I have a Serta independent springs mattress that was around $700 and this one has the same "feel." I would recommend it for anyone who needs a mattress. I use mine as a daybed in my 2nd bedroom/office/guest room. The mattress with tax came to about $200, which is a whole lot less than buying a Serta!

    I want to collect the mattress from the store, but i am not sure whether it will fit into my car or not..
    by deepdeo 8/8/2010
    • 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.

    • yes!! i just got my full sized mattress and it easily fit in the back seat of my 2 door honda civic. i would guess a queen would have fit as well. not sure about a king sized tho. it is pretty heavy though so its really a 2 person job.

    • guess it depends on size you buy but worst case you could put it is trunk and tie shut if it does not fit back seat

    • 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.

    • Yes it will. It's in a box with rollers but it is heavy. I needed my boyfriend to help lift it. I recommend putting it in the back seat.

    • the mattress is rolled up and shipped in a box. It would still need either a plywood surface, box spring, or slats less than 3" apart.

    • 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!!!

    • 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!

    • This mattress comes folded in a box at Walmart for easy pick up. When you get it home, just open, let it breath for an hr or so and it's ready to sleep on.

    • The mattress is shipped in a box . It is in a plastic bag and then vacuum sealed like those space bags . The mattress compacts to about 2" thick then folded over and rolled up . 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 .

    • 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.

    • No it does not at all need to be on a plywood surface. It actually doesn't even need a boxspring. 'In a box' means just that, its delivered in a box, rolled up.

    • 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

    • No! The box is pretty small. When you open the box the mattress is tightly air wrapped in plastic. Once you lay out the mattress and cut the mattress it blows up immediately which is totally amazing. It's totally comfortable.

    • I would say no. Once you open the vacuum sealed bag that it come in it's pretty much open for good.

    • No, definitely not. It is vacuum packed in plastic and enlarges dramatically after you break open the plastic.

    • Not a chance. The box is about 3' high and 1.5' wide and the matteress is much bigger when it regains it shape

    • No. Once it is open from its condensed shipping state, it is like a regular mattress.
