Style: 12 Inch
Ive been sleeping on my mattress for about 12 days now, and its grown on me. I did find it a bit too firm at first but as the days have gone on ive adjusted to it. I live in an RV and getting the mattress inside and unrolled was actually not as bad as i thought it would be since its a small space. It didn't combust when i started to slice the plastic, and there was no smell. I will say that i ordered the queen without measuring thinking it would be the same size as the other one and it is not 😆 it hangs off the frame about the length of my hand middle finger to wrist. Im not sure what size the other bed was, but it’s my own fault so fare warning to people.. get measurements! I didnt let it inflate the 72 hrs like it instructs, it was pretty much ready by that night, and well, i had no other option than to sleep on it. As far as not being able to feel another person’s movements, id say thats pretty accurate. Of course you can still feel something but it’s not aggressive. On my old mattress i wouldn’t be able to sleep on my left hip at all because it would be in so much pain, i think i have inflammation in there somewhere, but since getting this mattress I've been able to sleep on it all night no problem. Im not waking with aches and pains in my back either. Honestly its a great mattress for the money!

This bed is marvelous. It is so comfortable. Hubby likes a harder bed and I like a softer one. This works for both of us. I never liked the topper we have because you sink into it. You don't on this bed. I don't even know how to praise it enough. We are both just so happy. We have only slept one it 2 nights but the difference was immediately felt. My back pain seems to be easing. Just WOW. I haven't noticed any side dipping as others said they felt. Unwrapping was simple. My son brought it into the room and we opened box and took it out. It does come well wrapped in plastic. So we had to take the first layer of suran type plastic off. That was kind of a pain in the bum but not hard. Just set it on it's side to start. Once you get to were the two types of plastic meet, we layed it on the frame to finish unwrapping. The plastic cutter it comes with makes cutting the mattress plastic bag easy peasy. It does open and inflate quickly. Just open the door section and then go up a side. Lift it and pull the rest off. Again, super happy. Be aware it is heavy in the box for me. My son carried it. Hubby is 6'2 and I am 5'2. We both fit great on a queen size and it doesn't dip and roll me over onto him like our last mattress. Recommend absolutely buy. I am definitely getting 2 more for the kids. These pics are 5 minutes after opening.

The media could not be loaded. Compared to my mattress that was replaced, this has been the most supportive mattress that I've owned in quite some time. It was also very gentle on the bank too. My previous mattress was only used for less than 2 years and within that time, we had so many issues with it which caused a lot of back and neck problems. Since getting this mattress, the first thing I noticed was the less and less neck pain I was starting to have. I then started noticing that even my back pain wasn't as intense and strong as it used to be. Another thing my spouse and I noticed was that we've actually started falling asleep faster and staying asleep longer. I used to wake up in the middle of the night with neck, hip and back pain and would have to take another pain pill to help me get through the night to morning. Since using this mattress, no more having to take pain pills before, during or after sleeping. This mattress fits all of our sheets and blankets so there was no need to go out and purchase new ones. Even fit on our bed frame perfectly without having gaps between the side rails and mattress. We did allow this to completely inflate before laying on it, we ended up going out of town that weekend so it worked out for us. This has truly been one of the most supportive beds I have slept on and the bonus was that there was no weird chemical smell to it either.

I ordered a queen 14" and Lord, lemme say that box was HEAVY! Poor Amazon delivery guy, I'm so sorry! Mattress was very well compressed in plastic, follow the instructions and you won't have any issues unpackaging it properly. It does come with a small bag with a 'safe slicing tool' and instructions inside the box. Had no weird 'plastic-y' smells or anything once the plastic was cut off to let it fluff up. It puffed up very quickly, but we let it sit 24 hrs before we put it in my daughters room. Her old mattress was literal springs and fabric at this point and so uncomfortable for her. She is LOVING the new one! It's pretty firm with good support from the pocketed inner springs. The top foam and gel layers have been great, adds the softness while still being supportive. She's had zero complaints after a week on it. Will update if anything changes!

I bought this for my mom, and she’s been happy with it. It’s comfortable with the right amount of support, and it stays cool overnight. She’s been sleeping more soundly, which is what matters most.

I had hoped that a few months would feel more comfortable, my husband is comfortable, but I am not. It is not so much medium firm, as firm. The mattress pad I ordered hasn't helped beyond not feeling the quilting on the mattress. Sleep quality is okay.
