I have been using this frame with a 100 lb mattress since February (it is June now.) I havent really put it through any strenuous activity, but its holding up perfectly so far. And Im no lightweight. The pictures are very misleading however. There are only a few ways the picture could actually represent the item delivered. 1) they put air into the headboard under the material, to make it look fluffy. It is flat as flat can be, but does have a bit of padding. 2) those wings lol if you follow the instructions, they will absolutely not look like the picture. Maybe they attached them in a manner which caused them to extend about two inches more from the headboard than they would if assembled according to the instructions (like holding them out from the headboard as far as they could and using duct tape to hold them up there just for the picture, etc)3) magic4) mirrorsThat said, the assembly was a breeze (less than 30 minutes.) It looks good even with the non-puffy headboard or the tiny wings (I didnt leave them on.) I miss how it should have been really fluffy and cozy, but it is still very good. The slats are well made and one of the best things about this bed frame. They come already connected and you just roll them out onto the frame. The exterior rail of the frame has Velcro and the slats have Velcro on the exterior sides which attach to the Velcro on the frame. Also the slats are flat, not round. I cannot feel them underneath me. I have to stand on the bed to change my lightbulb and it has not failed. I feel like its a very sturdy frame which I will have for at least several years, and it looks good, so totally worth the money.
