I ordered two of these mattresses for a daybed and trundle. They do hang over the frames just a little bit, but it isn't a problem. The 8 inch thickness is just right for the trundle..along with a mattress pad, sheets, and blanket..it just does fit under the daybed well. There have been three different guests sleep on the mattresses..all of them really enjoyed their night's sleep! They each comment on how comfortable the mattress is. I slept on it one night to try it out for myself...It IS very comfortable! You kind of sink in to the mattress, yet have full support with no pressure points! Body doesn't hurt! And the memory foam does not make me warm. I love these mattresses and highly recommend them!

I always hates traditional mattresses. This memory foam mattress is awesome. I've never felt such a peaceful and more relaxed sleep in years. I actually notice the decrease in tenseness in my body. My children say you can't lay on this bed without falling asleep. Highly recommended!!!!

Unpacking was easy and the mattress unfolded to over 7" immediately. Within 2 hours it was at the full 8" thickness. There was a warning enclosed about the odor but this was my 2nd one of these and neither had any odor whatsoever. It is just the right firmness to give me a good night's rest and my arthritic body really appreciates that! I would highly recommend this product to anyone with back or neck pain.

Mattress arrived neatly in a box which was easy to carry upstairs into our attic room. Within minutes of opening the mattress, it expanded to queen size. The mattress NEVER had an odor. The price was so reasonable, even with the $27 shipping, I couldn't have bought one cheaper anywhere and I did alot of online research before I bought it. It is the most comfortable mattress we have ever had. No more back and shoulder pains! Mattress is on a platform bed. Very satisfied with purchase and quality. We love it and recommend it highly!!

We purchased this bed for our 3yr old. She started sleeping through the night since we switched from her old crib (toddler bed) mattress to this new mattress. I couldn't believe how much more sound she sleeps now. I was really just looking for a good value and "comfortable enough for a kid' type of mattress, but it is way nicer than I expected. We are very happy with it.

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!

Purchased this mattress as an additional sleeping mattress as a trundle under a daybed. The memory foam is quite comfortable and surprisingly still firm for a memory foam. It conforms well, but does not have that complete "sinking" feel after laying on it for a while. Have had no complaints from anyone who has slept on it. Very nice protector covers the entire mattress and is as soft as a sheet, so no crinkly-crackly sounds when you move around on the mattress. A normal fitted sheet also fits the mattress well after fully expanded and having the cover on. Arrived rolled up and very flat, but expanded to full extent within a short period of time. Was ready to sleep on the same evening. Odor was very faint compared to other memory foam products we have owned. Very pleased and would recommend purchase if one is on the fence with a decision!

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

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 :-)

I was a little worried about this purchase because I was purchasing it for a daybed whose dimensions were half an inch narrower and half an inch shorter than the dimensions of this mattress. I called the manufacturer and they told me that the mattress has a bit of give in the foam and that it would work. It worked perfectly. It took this mattress about three days to reach full height. I also bought the regular size mattress for the trundle, and that one seemed to expand to full size in about a day, so I'm not sure why this one was different. Maybe it's compacted more--it's bigger yet arrives in the same size box as the regular twin. Anyway, the mattress is super comfortable. Oh, I also asked the manufacturer if it has to sit on a solid surface (like a full board) because my daybed has slats. They told me the slats would be enough support--my bed has 15 slats with a couple inches between each one. The odor from the bed is pretty strong but not horribly unpleasant. It took about 4 days to dissipate to the point where I wanted to put sheets on it. My teenaged daughter has slept on it a couple of nights and says it's comfy.
