When I saw these screws attached to the spring legs that are supposed to extend to the floor to support the bed, I knew they weren't not going to work and I was right. The screws are just too weak to support the weight so they bend and come loose. The result is a VERY wobbly bed (it's as though you are sleeping on a waterbed). This is absolutely poor product design through and through. Even after we put thick furniture felt underneath, the bed is still shaky which goes to show the low quality of this bed. That's the downside ordering from Wayfair. This is the second time I ordered a bed and both times there's quality issue It's a hassle to return and it costs $90 shipping fee for return. NOT WORTH IT!!
