10"Charcoal Hexagonal Pattern Memory Foam Mattress

So far so good with this mattress. It seems to be well made. You would never know it came out of a box. It's fairly firm too yet soft. I am using for my sons bunk bed and it fits great. He thinks it's a little firm, but would be better for an adult.

I've purchased these 'expanding' (AKA; Bed-In-Box) memory foam and composite coil/foam mattresses since they ever been available, so I've got pretty realistic expectations.
Opening and deploying (expanding) this mattress was pretty standard fare. I've learned to allow the full 24 hours for these types of mattresses to expand properly. It also makes a difference in the odor these foam types emit when they are new - It's normal and not unusual - expect it.
Hint for best results; Release the mattress from packaging & place on a flat surface for ~12 hours, then flip the mattress over & allow another 12 hours.
The expansion is complete and most/all of the odor will be gone. This mattress in particular did not have much odor at all, which was nice for a change!

Everything size-wise is correct for this mattress. It fits normal twin fitted sheets just fine...another welcome attribute!
I use this mattress on my adjustable bed and right away the amount of flexibility was noticeably good. Some mattresses are stiff and the internal layers don't allow for much flexation...this one is doing great in that department!
As for comfort? The 'medium' rating feels true! When I lay on it, the upper layers are very conformal and the inner layers give the firmness that makes it just right. I own a 2" mattress topper but did not require it on this mattress. It's just fine right as it is made.

Edge firmness is uniform as well in respect to the feel of the entire surface - I'm not falling out of the bed when I go to stand up due to a soft, soggy edge ??

So far I'm delighted with the way this thing feels. Fours nights into using it and nothing to complain about. When moving this mattress around, I noticed that it holds its shape and is not like handling a wet rag...it's not overly weighted and fairly easy to manipulate.

Since I replace my mattress every 16~24 months, I can appreciate the price point for this mattress. If you use and adjustable bed, you'll appreciate this mattress a lot. It performs very well and doesn't have 'shape memory'
As for longevity, only time will tell...I will certainly update my comments if there are any issues.
For me, this is a win - just what I was looking for - Two thumbs up!

I got this to put in my daughter's room. She likes to feel of it and she likes the coolness of the gel. It's 8 inches so it's not real thick, but it does the job for her. I think I'll probably add a memory foam topper at some point.

My son loves the comfort of this mattress. Now springs to poke him.

Very nice for the price!
