The original slats are too soft and do not provide enough support. I added 13 2 and a half thick pine boards in between the original boards and switched the middle support beam (originally particle board that broke) for a slightly thicker pine board (as pictured above compared to another reviewer that I used as reference to build). Now there is much more support. The bed is made VERY cheaply for how much they are charging. A lot of the wood used to make the bed is particle board laminated with a fake wood grain. Don’t waste your money. You will end up spending more to fix the bed than you would spend getting a quality bed originally.
