Using this mattress with bunk bed tip: Purchase a masonite sheet to lay on top of the slats to support this mattress - very inexpensive and home improvement big box story will cut to size. Also, carefully measure the space compared to the specs of this mattress. All twins are not created equal. These twins are much larger than the ones we replaced and I held my breath not sure it would fit in the space. It barely did but sheet changing on the top bunk is going to be rough. Now for the review: We bought these as replacement mattresses for our children's medal frame bunk beds. Realizing firmness/softness is subjective I thought these were supper hard but said nothing to our kiddos in case they didn't notice. Well they did notice and complained like the dickens. I even cancelled a pick up I'd scheduled for our old mattresses concerned we might need them. They complained every night for a week until I ended up purchasing an inexpensive topper off Walmart.com hoping and praying that would do the trick. Fortunately it did. A week after adding the topper, the last thing my daughter said to me on her way to bed tonight was that she loves her new bed. Thank goodness! I was looking for something softer to start with but could find nothing less firm in a twin size at Samsclub.com

After sleeping over 30 years on water beds, the last one a dual-chamber, pillow top costing over 8 times the price of this mattress, we decided it was time for a change. This mattress was easy to set up (I really missed the hoses and adapters and mattress burping) and after a couple of days the mattress had fully expanded and the odor had disappeared. We purchased a mattress pad to offset the heat reflective properties of the foam and are now sleeping like well fed, clean diapered babies!!!

We bought these as bunk bed mattresses for our twin 7-year-olds. We replaced conventional mattresses that were a few years old because one of our kids was complaining every morning about back pain. Since the mattress has been in place there has not been a single complaint. We're happy with the change and happy with these mattresses. We had them delivered and they come compressed in manageable although deceptively heavy boxes. No problems with set-up. We would buy these same mattresses again.

Originally wanted this bed for my 5th wheel.. Leaving my old queen matress behind and moving I decided to buy it for my new house. Its not as firm as a tempurpedic. I have fond memories of them from hotels..and the feeling of waking up like I never went out the night before. This isn't quite that but compared to a regular matress its very comfortable - instantly. Tempurpedic are sometimes brick hard at first then slowly soften up and cradle you. for $1000+ savings, really is there any room to complain? It does "smell" for a few days to a week but anything urethane/rubber/plastic will. the 8" is fine for men - we dont care if sheets dont fit right. however if you want sheets to "fit" height wise, women will definately want the 10-12" stack for sure. From everything I've read though the comfort factor will not matter regardless what height you pick, its the same. I'd buy another for sure and this one will probably make it's way back to the RV.

If you are wanting the quality of a temurpedic, this is not for you. Its ok and does the job, but adults sink in deeply. I can feel the metal foundation when I roll and Im not a fat, heavy person. If for a child, this would be fine and do the trick. Over 150 lbs pay the money for something nicer.

We bought TWO (2) of these beds to replace our 13 and 15 year old daughters' worn out spring mattresses. Of course, when they 1st laid down on the bed, they said it was too stiff. However, after a few night of quality sleep - they are NOT complaining. In fact, they said they liked their new beds... So for the parents of these girls, we give these beds a 5 STAR rating :-)

We have there more plush 13 inch version on our bed at home. But this skinnier version for our camper and was like music to my body when laying down on it compared to the bed that came with the camper. Immediately comfortable and immediately great night sleep. Love these mattresses!

It is hard as other have mentioned, but in less than 2 months there is a noticeable sag where I typically lay. It's like falling into a well worn hole and after only 2 months! The warranty is worthless since if nobody is on the mattress and you lay a straight edge across it, it is not apparent. But lay down and immediately you roll into the "hole". TWO MONTHS, I was hoping for better!

I bought this bed in January, and I am writing this review in April, 3.5 months later. We purchased 2 Twin XL beds, and the value was great for the buy. My bed was comfortable in the beginning, but I experienced hot spots where patches of heat gave me great discomfort. The bed also began to build areas of sinking and would not plump back up like memory foam is supposed to. We also discovered mold growing on the bottoms of both beds for some reason even though we use well ventilated bed frames built for memory foam mattresses. I am going to try and return these mattresses, since I bought 2. I suppose memory foam is quite popular nowadays, but I prefer the traditional spring bed w/ maybe just a memory foam topper if I really even need that. Memory foam attracts too much dirt, moisture, and heat--- and I just need a nice place to sleep every night without worrying about sinking into a fussy mattress. I don't think the great price makes up for the trouble we are having now.

I ordered these online in fear and trepidation. They arrived timely, were really easy to unpack and put on the beds, guests arrived that night.. No odor and they loved them! All around great experience. I will never shop mattresses any other way again!
