I replaced the two twins on my adjustable king bed with the same manufacture king size. Fit great and is just so comfortable. I love it.

Because it was an Amazon mattress purchase, I wanted to make sure to leave a real review. I bought the firm 10inch mattress due to my size (6’6, 270lb), because sometimes medium firm mattresses aren’t what they say they are. Also, I thought that if it would’ve been too firm, I could get a 2inch mattress topper to soften it, instead of getting the taller mattresses and not be able to adjust to comfort. Also, I was hesitant to by memory foam because I heard hybrids held up better with people of size. Okay to the real stuff! This mattress feels amazing on my back and side. It’s firm but not too firm where it’s uncomfortable. I’m able to feel the relief on my lower back and it’s perfect for my higher platform bed with the built in storage drawers. It’s also sturdy for kids being on it and etc. Doesn’t sink or fall in during intimate moments either (for those who wonder). All in all, this was probably one of the best blind purchases I’ve made and the price makes it more quality. Whenever i have to get another one, this will be the first company I go to look at.

This bed is extremely uncomfortable and I hate it. I have been using it for just over a year. I was hoping it would just be an adjustment to a new mattress but when my SO hates his side as well. When you adjust the bed up at all the mattress gets a really bad crease and fold in the top making it hard to sleep on. The reviews had me fooled into thinking it was a good mattress but it was a very expensive waste of money.

I bought this mattress for my 27 yr old son, after losing our home and town in the Camp Fire in Paradise, CA on 11/8/2018. He really likes this mattress. He wanted a firm mattress and says this is very comfortable. It’s firm, yet it gives enough to ease the pressure on his body. He sleeps very well on this mattress. We’ve had many memory foam mattresses the last 30 years. He says this is his favorite.

Bought this bed a few months ago and my back has killed me ever since. I can’t stay in it for more than five hrs and I have to go sleep on the couch. Now I’m stuck with an expensive mattress that doesn’t work for me.
