What is the trial period for a mattress?

Diamond mattresses are built with better quality materials on a firmer, more supportive base than other memory foam mattresses on the market. We guarantee the construction, materials, durability, and quality of every Diamond mattress for as long as the original purchaser owns it. We know that trust from our customers is everything, which is why we want to bring you quality over quantity. We believe Diamond should be the last mattress you’ll ever need to buy, which is why we feel confident in our 120-night trial period and a warranty that lasts forever.
