Olee Sleep 9 Inch Full Size Memory Foam Mattress - Gel Infused Cooling Technology for Pressure Relief & Comfort, CertiPUR-US Certified Medium Firm Mattress in a Box | Perfect for Guest Rooms, Dorms & Small Bedrooms

This mattress delivered a lot of bang for my buck. It was delivered in half the time estimated and was well-packaged. I opened the box, removed the plastic, and was prepared for a long wait for it to fully expand - but it was done expanding to the full 7 inch height in less than an hour. Upon returning to check on it I found my cat had taken quite a liking to it, and it absolutely melted my heart to see that his little paws sunk a little bit into the mattress with each step, though he was fully stable on his exploration journey as the mattress is very soft on top but dense and supportive below. Once I finally got him off of the mattress I moved it into the bedroom where I had been assembling the frame and it was fairly easy to move and not too heavy. I then added bedding and had some of the best sleep of my life. There's no plastic-y smell, there's no weird sagging, and it's not too soft or too firm. The gel foam layer kept the temperature well-regulated despite how much the temp changes through the night in AZ. I was afraid I wouldn't wake up for work this morning.As much as I enjoyed the first night I'll update in a year, or if something happens; from what I've already seen from this mattress I would definitely recommend it for short-term use and I have a good feeling about long-term use as well.
