So, we have purchased two double size frames and one king-size frame from wayfair.ca with two different orders. They were delivered on-time. Installation was easy - we just used the instruction manual. Double bed frames needed some extra power but the king-size frame was pretty easy to install.

One of the headboards of the double size bed frame was damaged in transportation. I have contacted Wayfair, they were extremely fast in replying to my email. They have super friendly staff and very fast services. I definitely recommend Wayfair to my friends and family.
