We’re passionate about making a quality mattress that will give you the best night’s sleep. That’s why we use only the finest materials and hand craft each mattress to our rigorous standards of fine craftsmanship.

Mattresses & Foundations

We’re confident that you’ll love your new mattress, but if something goes wrong we’re here to help. Returns and Exchanges are processed through our warranty department according to the terms and conditions of our warranty. For warranty details click here.

Adjustable Bases

While we do not offer returns on our adjustable bases, we do stand behind their quality. If you have any questions or concerns with your adjustable base please call us and we will help you get the issue resolved right away.

Pillows, Mattress Protectors, Mattress Toppers & Other Products

Due to the personal nature of such items as pillows we do not accept returns on these products. However if a product is delivered damaged or is defective we stand behind our products as they each carry a warranty to protect your investment.

Retail Store Purchases

If you purchased a Diamond Mattress product from a retail store that carries our products, your purchase is subject to the return policies of that retailer.
