## Questions & Answers

**Q: Is this the laze mattress?**
A: It's the Sealy $314.00  one.  I didn't see laze anywhere on it.  Most reviews are good but in n way did I find this mattress firm.  I suppose I really like rock hard but lying toward the edge of it to accommodate my dog, of course, the mattress would so compress that I felt like I would roll out of bed.  Now that isn't even a little firm  and so now I'm back on the foam mattress I purchased from the mattress shop Sleepys like six years ago and love it still.

**Q: I need to return king size mattress**
A: Not sure why you are asking me this question.

**Q: If I buy standard sheets would it fit this mattress for anyone that would know ? Or does this mattress call for deep fitted sheets ?**
A: Standard sheets would fit this mattress perfectly.

**Q: Does the box say certiPur**
A: Not sure because I opened the box, removed the mattress and threw away the box.

*by T***N on Reviewed in the United States 🇺🇸 on 21 May 2023*

We have switched our mattresses out to this brand/model. THE most comfortable mattress out there. We love them and our AirBNB customers make comments on how comfortable these are. We even changed out mattresses in our RV to this one!

### ⭐⭐ 







  
  
    Never fully swelled into shape1
  

*by P***L on Reviewed in the United States 🇺🇸 on 15 August 2022*

We had high expectations for this mattress. We had recently slept on a similar Sealy foam mattress and just loved it. It arrived in a box and when we removed it, we were surprised at it's shape. Not like a cylinder, more like a potato. The ends were very tight? After two days waiting for it to fully inflate we decided to try sleeping on it to help it finish swelling to proper size. The sides are round and not anything like the photos shown on the web site. It is comfortable, but more firm than what we expected. Can't sleep near the sides!We are going to git rid of this mattress.
