## Questions & Answers

**Q: How is the edge support on this mattress?**
A: I’ve got a $2,500 tempurpedic and this mattress in the guest room (where I sleep a lot) and can say the edge support on this mattress is one area it’s not as good. That and you sink into this one a bit much which makes moving around more difficult. BUT I gotta say overall for 10%!!!! of the price it’s a comfortable mattress.

**Q: Is this mattress good for heavy people?**
A: My son weighs 270, sleeps alone.  Mattress is separating (top layer is offset about 3-4 inches on one side)  I think it's just a general defect in the manufacturing.  He bought the mattress in the fall of 2017, so it lasted for about 2 years (about $110.00 per year.  My wife and I love ours of the same thickness, but then I only weigh 140 and she's about ten pounds more.

**Q: I want a firmer mattress. How many inches should I purchase?**
A: For me, I wish I had some of the issues some of the people answering this question have had.  I like a firm mattress.  I weigh just over 300 lbs.  I am a large mammal.  I have the 12-inch mattress, and every night I sink into that thing like I am sleeping in jello.  I find myself moving to different parts of the bed to get back some firmness.  Eventually, I sink in, and then move.  Repeat as necessary.  We also have a skinny version of this in a twin bed size.  That is firm.  I will take naps on that bed to get the sleep I am missing in the King-sized 12-inch thick bed.   My experience (which, admittedly, is different from many of the others answering this question) is to get the 6-inch version if you want a firmer bed.

**Q: is it hot?**
A: This bed is comfortable at first but then you fall into a peaceful slumber and wake up full on overheating! I wake up every single night to strip down out of pj' s and uncover myself and even feel like I desperately need ice water to cool my body temp! I am naturally cold and the only one in my family of 3 (us and our 4 year old) who is always freezing and uses a blanket at night. 
I have been up every night for the last 3 weeks MISERABLE from the heat! I have ended up on the couch 1 out of 3 nights. I was worried about switching to a memory foam because my fiance always runs hot. He complains about the sinking but I can't handle the heat!
