Did some research since I wanted a metal bed frame to replace our squeaky wooden bed frame which was only about 5 years old. Had enough of noice from this frame. Did some on-line research and came up with this Mifflinville unit at Wayfair. The information on the site was great and I ordered one. It was here in about 4 days. Installation instructions were precise and happy installation was perfect. Happy, quiet nights are here again. Totally recommend this product if you want a quality product. Perfectly designed for the change I made.
