Perfect firmness

Honestly,this mattress I just got from Kizreo totally blew me away! It's the perfect firmness. The moment I lay down,my whole body felt gently supported,super comfy! I've never slept this well in my life! Used to toss and turn all night, but now I sleep straight through'til morning, wake up with no back pain.My hubby says he feels like a whole new person when he gets up too.

great for spine

I have been dealing with ever increasing spinal pain for the last 4 years. So I looked around a lot before I picked this one. I was worried about if it may cause me back pain, but was happy when I slept the best I ever had the first night I used it. and i have had much better sleep since. If you are a bit plump or have spinal pain this worked for me and I love it.

An Outstanding Buy! As Promised!

I was so skeptical about a mattress in a box. It was our first experience. I have to assess more over time but we did not have to wait for it to fluff out. It was sleep ready from jump but we waited anyway. The comfort level is outstanding. It is firm but soft. I am an all-side sleeper but mostly a side sleeper and this worked beautifully. I will be purchasing for my guest bedroom as well. I love it! Great buy!
