Viscountess Queen Mattress 14inch Gel Memory Foam Hybrid Mattress in a Box Innnerspring Medium Firm Comfort

I ordered 2 twins for a daybed with trundle. I ended up ordering these after an order from a different vendor failed to be delivered in three weeks. This vendor had it on my doorstep in 3 days. The max size for sliding the trundle under was 10” so I got the 10” mattresses. I read the reviews that said the full height was less than 10” so I figured it would fit easily. I cut the shrink wrap very carefully with a pair of scissors due to the warning on the package. Make sure that you cut open the package so it unrolls away from your body because it happens quickly and forcefully when it's ready to give. If you have a queen or a king, maybe have a second person or cut from both sides and do the middle last. Each of the mattress expanded to full height immediately. I think the issue is that some people are measuring from seam to seam instead of from the lowest point to the highest point. From the lowest point to the highest point was over 10 inches and from seam to seam was 9 1/2 inches. The mattress was perfectly comfortable for both side and stomach sleeping positions. The only issue (true for all hybrids) is the edges lack support so if I get too close to the edge you notice it. If you're lying more than 6” from the edge, it's not noticeable. It wasn't particularly noticeable sitting on it on as a daybed. I do not feel the springs when I sit or lie on it. I weigh 200 lbs and find the mattress completely comfortable.

This mattress came quickly and raised to 12 inches within 4 hours, but I didn't use it for over 48 hours like recommend. The only problem is you can't really on the edge, you have to make sure that you are completely on the mattress. I would definitely recommend.
