overall not so bad

I wasn't too sure what to make of this mattress until I finally tried it. I gave it 6 days undisturbed to expand. It eventually reached 7" to 7.5" inches variable thickness. The current pictures shown of the product are fairly accurate compared what to was posted last year when I bought mine. Instead of being white with squared corners, it resembled a Toaster Strudel. At any rate, despite being a bit wonky, it did turn out to be very comfortable and firm enough for me (and I'm, uh, 'big boned' shall we say). The bottom line is the earlier reviews, whether positive or negative, or rated 1 to 5 stars seem about right to me. I can see it being a hit or miss, love/hate type of product; especially if your box spring or base isn't solid and smooth. Best bet would be to buy it on sale if you can ... and cross your fingers.

Good, Finally.

Purchased on sale last December. It took about half a year to extend to the standard product dimensions :8 * 54 * 75 . Finally.

Cheap bed but its feels lumpy when you sleep on it. The middle sags down to far and doesn't provided enough support, doubt it is 8", more like 5". Buy the one with the springs in it.

NOT 8 INCHES & Never in stock

Fast shipping so thumbs up to that, super comfy actually a nice mattress but is not a 8 inch more like 5.5-6 inch mattress after over 72hrs of decompression and working out the corners of the mattress.So if your looking for a 6 inch mattress this be it but bestbuy full out lies about product thickness just so you know

  • from Levis, qc

Love it. Like advertised 6-8 inches. Very cheap and minimalist bed.

Bunk Bed Mattress Replacement

We purchased this bed online and had it shipped to our door. Once you take it out of the box you have to let it sit for a few hours to allow the foam to expand, once installed, our daughters loved it. It's installed on a wooden bunk bed - solid board beneath with cross members. The single bed we purchased for the top bunk is only 6" thick, I would have preferred a slightly thicker mattress, but it too is a welcomed addition to the bed. No springs, memory foam, great rest each night. We purchased both mattress last month. So far - Fantastic!

Dissaponted at the mattress and best buy

This mattress is not firm at all. it's too soft. if you are close to the edge, you will tilt over.No support whatsoever. I put it on the hardwood floor just to make sure it wasn't the bed issue. This is misleading advertisement. Very disappointing. Contacted best buy for exchange or return and was told I can't return mattress that are opened. This mattress came in a box with the mattress rolled up. How am I supposed to let air for 48 hours in the plastic bag sealed.

Limited to no stock availability

I am extremely disapointed. I needed this item for our camper. Unfortunately the stock was limited and sold out immediately. After reading reviews this seems to be typical of bestbuy with stock issues. I attempted to order at 12:00 mid nite on Dec 26th online (sask time) and was told it was sold out already. How is this possible?
