I really wanted to love this mattress and I still am trying to. Unfortunately, I am with all the other negative reviews. The original mattress they sent me did not expand properly. It's supposed to be 80 inches and it is only 72 on the one side and 74 on the other. Because of this, there is a large gap between the headboard and footboard my pillows. Keep falling back over the top of the bed or my feet hang over the bottom if I stretch out. It also means my sheets don't fit properly. Most mornings, I wake up and a corner of the sheets has slipped off somewhere. Unfortunately, that isn't even the worst part trying to return. This has been a big inconvenience. I used their AI response for the return and I thought it worked out great until I got the email later saying I needed to place everything back in the original packaging and box and place it outside for FedEx to pick up. Clearly not possible. After waiting over half an hour on the phone, the agent I got was having phone problems and we got disconnected. Never got a call back. I tried their chat option and after going through the entire explanation process and providing lots of information we were near the end of the chat and somehow I got disconnected. I know, for a fact, these issues are not on my end. I finally got through to another agent after another 10 minutes of waiting. She was nice enough to change the carrier to someone who would not need the mattress in a box to pick it up. Unfortunately, I have no confirmation of this, I was told someone would call me in a couple days to schedule pick up. Hopefully that happens! I think my next challenge will be making sure they don't pick up this mattress until the new one has been delivered or I will have nowhere to sleep. I really hope this new one is not defective, I bought it over some other ones I was looking at on Labor Day, which means if I don't get lucky with it, I lost out on other sales. The only reason I gave it two stars is because I do feel like it would be a good mattress if they didn't have so many issues with it expanding. I had a regular memory foam for the past 12 years that was definitely needing a replacement so I'm sure part of thinking it's comfortable is due to going from such an old mattress to something new. The only complaint that I have with the design of the mattress itself is the removable cover. I'm hoping that it's the way it is because of the mattress being too small. But it moves around a lot under the sheets so when I toss and turn at night, I can feel the sheets and the mattress cover moving around, and I don't like that. Again if the mattress was fully expanded, maybe that wouldn't be an issue.
