100-Night Sleep Trial

To ensure your comfort, we offer a 100 night comfort guarantee. In order to allow your body to adjust to the new mattress, we ask that you sleep on your new mattress for 30 nights, but no more than 100 nights before making an exchange. The comfort guarantee is a one time exchange and only applies to mattresses $499.99 and above. If you are not comfortable, you may select another mattress of equal or greater value (you simply pay the difference in price) within the first 100 nights. Removal of the law label, damage, abuse, soiled or stained mattress are considered unsanitary and will void your comfort exchange. Purchasing a mattress protector is recommended to ensure a stain free mattress during your 100 night comfort guarantee. No cancellation may be made on the original purchase. The Comfort Guarantee does not apply to furniture, adjustable beds, custom sizes , mattresses sold as-is, warranty exchanges, pillows, protectors or sheets. There is a mandatory $99.99 redelivery charge if local delivery is requested. We do not charge any restocking fees, unlike our competitors. This policy applies to mattress purchases only. Adjustable bases, foundations, and accessories are final sale.

Warranty

The typical mattress is replaceable under warranty guidelines if any part of the surface area compresses 1”(-.5" vs. the industry standard) or more for a spring bed and .75” or more for a foam bed. If you feel that your mattress is defective, simply contact our customer service department or your local Ortho showroom with your invoice. A service form will be submitted and a third-party inspector will be scheduled to perform an in-home inspection for a fee on your mattress. Once verified by the inspector as a warranty defect, our customer service department will contact you to offer the warranty replacement credit with instructions to reselect a product (or products) of your choice that we’ll be delivered to your residence in exchange for the defective product.

Care

The occasional rotating of your mattress will help in the proper conditioning of cushioning materials, preserve comfort, and maximize its life. It is important to keep your bed clean and dry. Make sure to always use a mattress protector. To prevent wear, don’t excessively bend, do not jump or stand on mattress. Also, vacuuming the mattress annually helps with allergies and keeps the bed in good shape.

FAQs

What are the advantage of buying a factory direct mattress?

Factory direct means you are purchasing a mattress from the same company that makes it. This allows for the best price on a mattress, as our factory direct business model eliminates the distribution and middle-man costs other brands must pass along to the customer.

Where does Ortho Mattress make their beds?

We are very proud to produce domestically at our Phoenix, AZ facility.

Do Latex Foams sleep hot?

Latex is a naturally derived product that allows for better dissipation of heat, and is one of the coolest materials to sleep on. As a result of the curing process, the structure of latex foam features pincore holes that allow for more air flow.

Super service and product

"Justin was really helpful in showing me the different mattresses and helping me find just the right one. Slept on it last night and it was wonderful."

Cherrell (5/5)

Incredible Mattress!

"We’ve had our bed for the past few years now, and we absolutely love it. I travel a lot for work, and the number one thing I miss—besides my wife—is this bed! It strikes the perfect balance: not too firm, not too soft—just incredibly comfortable every single night. We both tend to sleep warm, but with the Lansdowne, we stay cool and comfortable no matter the season. It’s been a total game-changer for our sleep. Can’t recommend enough!!"
