I had back surgery and could not get comfortable in my bed. I thought about four very expensive adjustable bed brands until I found this one and read the reviews. This bed is perfect, comfortable, easy assembly, and does exactly what I needed my bed to do. My memory foam, 11" mattress fits and works perfectly with this base. i recommend this base to everyone, especially older folks and anyone with back issues, arthritis, sciatica pain, or swollen ankles and legs. This bed has given me the greatest pain relief that allows me to have a good night sleep.
