I bought the mattress and have it on a platform, so no box spring. It is firm and at first I thought it might have been too hard. But once you lay down it is nice to sleep on. I love it.

I was very skeptical about buying a mattress online. I knew Sam's Club would make it right if it didn't work out. This is a fantastic mattress and I am a picky sleeper! Med Firm to Firm, very comfortable.

I bought this for my teenage son and it has just been amazing. With his old mattress he would have the hardest time sleeping through the night, but with this one he has no troubles. I am 6' and 220 lbs, it is firm but yet still comfortable when I lay on it. But seriously I think the coolest part of the mattress was opening it up. It came in a box that was about 2' x 2' x 4' rolled up and vacuum sealed. We brought all four of our kids into the room when we opened it. I started with a small hole and you could just hear the air being sucked into the packaging and the small 4" mattress started to expand. The whole family thought it was amazing to watch and everyone wanted to test it out. It did take a couple of days to fully decompress, but really I would say it was 98% there almost immediately. I went to a couple of mattress stores and with the size and ratings of this mattress the best they could offer was a 10" and they were still like $20 more. One thing I didn't know and I'm still not 100% sure, but I received an email from Samsclub.com on the quality of service and it seems you can have this shipped to the local store if you don't want to pay shipping. Shipping was $40 and it may be a deal breaker for some, but this bed is worth the extra cost of you choose to ship to your house.

We purchased this for my 15 year old daughter. It puffed up nicely out of the rolled up vacuum sealed packaging in a shorter time than expected. Its very comfortable with the right amount of firmness for support but luxury soft. My only concern is the outer fabric does not appear to be water resistant like other mattress, but is a soft material. Not really an issue for a 15 year old though. She LOVES her new mattress. For the price we thought it a huge step up in comfort from those mattress offered in the club (limited selection, no twin pillow tops) and purchased it based on previous reviews on this site. We have not been dissappointed in our purchase!

After 24 hours the mattress hasn't expanded enough to fit correctly into my queen platform bed frame. The length fits correctly, but the width is a little narrow, leaving 1-1/12' of platform slats showing on the side of bed. This will probably not be visible once bedding is on, however when bed is in use, it will be. The box was pretty beat up upon arrival, tears in a few locations. Not sure if this has a anything to do with why it may not have expanded properly. I will give it another 24 hours. For now getting average rating.

We love this bed, it came compressed in the smallest box but man did it bounce back after it opened. It's our son's first "big boy bed" and we find someone sleeps in it each night with him because it's more comfortable than their bed. We purchased a full size mattress. We will be replacing our king mattress with this one the next sale.

I've had this bed a little over a year now. The frame is great and the set up is nice. First couple months were nice on it. However a year later Im having to order a new bed again... this bed does end up sinking where you lay at night and creates those dips. I weight right around 103 so I'm not that heavy. My bf is a bit heavier weighing a little over 200 lbs. the bed is very firm so if you think it's going to be soft think again. It doesn't have much "give". I will be giving my 5 year old this mattress since she Doesn't seem to mind the dips.

I cannot sit on the side of this mattress. it offers no support along the edge of the mattress and you slide off the mattress. The entire mattress has no edge support. If you roll to the edge of the bed while sleeping it does the same thing. I asked my daughter to sit on my bed and she said the same thing. Don't waste your money on this mattress

We ordered this item from Sam's Club. We are located in Florida and the mattress was shipped FedX Ground from California. Therefore it took almost 2 weeks to receive it after the delivery date was changed 3 times. The mattress was delivered in a square box that was much smaller than the mattress. It is fairly heavy and will require a couple of people to carry it into the house. Once you open the box and remove the packing, the mattress springs to life (Watch out). It looks great and looks like a quality mattress. It has a pillow like top, but the first night sleeping on it was difficult, because it was so firm (Hard). WE ended up putting a 2 inch memory foam pad on top of it and now it is fantastic to sleep on. It ends up being about 15 inches high above the box spring, so you need to be fairly agile to climb aboard at night. Yes I would recomend it as long as you are award of my comments above.

I bought this mattress 2 1/2 months ago and so this is only a preliminary review. We were sleeping on an all foam mattress from Sam's and it was just too warm in the summer. I have hopes this hybrid will be less warm during the summer months. It is firmer than the foam mattress, but that has not translated in to less comfort. If anything I would say the opposite.
