I have a 14” mattress with e 3” topper and I absolutely love it! The headboard isn’t as long as I’d like but it will do. I put this together myself and the directions were very easy to understand! Some parts would’ve been nice with 2 people but I was able to figure it out! I personally like how low this bed frame is but I can see if people with knee problems would have some problems. Overall I really like it!
