Hmm Idk where to start. Idk if it’s my bed frame or the box spring I’m pretty sure you sent me the right size. I got a king and it just bucks my bed frame out on the sides like the box spring is too wide or something I think if I screw in my wood slats that came with my bed frame first, that should fix the problem from the frame moving outwards. I’m just afraid after I do that, then the box spring won’t fit inside. Or maybe because it’s a metal Frame and I have a wood bed frame but in the picture there is a wood frame so that’s why I thought it might of worked. Hopefully I can fix this. Lol help. Until I can fix this. This box spring might not work with all bed frames!
