I purchased a King Wave mattress and paid for the mattress and foundation at the store. I took the 150 lb. mattress home in my vehicle and was promised that the king foundation would be delivered within the week. Later we received a message of a back-log and that they will begin shipping those foundations on February 19, 2021!. Today, January 27, 2021, I learned from the company that the back-log was over 800 nationwide. I would have selected a different mattress company had this foundation delivery date not been misrepresented. User's recommendation: Make sure your mattress company can timely deliver all paid for items.
