Before I bought this bed, I carefully perused the reviews. I was considering a platform bed but wasn't sure that my mattress (about 8 inches thick) was thick enough to provide comfort without the box spring....and I didn't want to have to buy one of the new, thicker ones. in addition to buying a new bed. What attracted me to this bed in addition to its great look was the fact that it could be used with or without a box spring. Problem solved! I couldn't go wrong. First night I slept on the bed with just the mattress and found it much too hard. Second night I returned to my accustomed box spring under mattress. Of course that worked well. And the mattress is not too high off the ground. The bed is versatile enough to accommodate any size mattress or combination of mattress and box spring.
