We purchased a Dreamstar mattress and box spring set in 2014 and enjoyed it for the first few years. In the last year it began to sink on both sides and my wife and I were getting back aches from the bed. Recently in April 2019 I contacted Dreamstar with the appropriate documentation and pictures and they promptly replaced the mattress under the 10 year warranty. I would recommend this company as they were a pleasure to do business with and with the help of the store in Mississauga where we purchased it years ago we successfully received a replacement and can sleep well again. Thank you Melissa for your great customer service.
