Surprisingly sturdy, no squeaks or wobble. 13 slats across make it able to hold my memery foam/gel mattress easily without a box springs or any extra foundation. The pegs that lock the slats in are a smart/efficient design. Beautiful bed...! Assembly takes a while. Lots of pieces, but pretty straightforward directions. Only reason I gave 4 stars is velcro skirt is not very well designed and doesn't lay right as shown in the photos. We will likely replace it with a traditional skirt or add more velcro. Otherwise, very happy so far. Probably would have given 4 and a half atars if it was an option.
