However, if you have a disability we are here to help you. Please call our disability services phone line at 912-826-0101 during regular business hours and one of our kind and friendly personal shoppers will help you navigate through our website, help conduct advanced searches, help you choose the item you are looking for with the specifications you are seeking, read you the specifications of any item and consult with you about the products themselves. There is no charge for the help of this personal shopper for anyone with a disability. Finally, your personal shopper will explain our Privacy Policy and Terms of Service, and help you place an order if you so desire.

Innovative materials work harmoniously to bring you restorative sleep with improved support, advanced motion isolation, and a lush cover made from plastic bottles diverted from the ocean. The Precision Support System™" offers 40% more support coils compared to Harmony models for even more head-to-toe support across the entire mattress, so you and your partner sleep undisturbed. Up to 100 plastic bottles collected by hand from coastlines and ocean-bound waterways* have been transformed into premium fabric to create a lush, durable sleep surface that helps contribute to cleaner water. Infinicool® Lux technology helps you stay comfortably cool all night with its breathable, moisture-wicking fabric infused with cooling fibers and plant-based cooling technology. Pressure-relieving foams help ease aches and pains while also creating airflow throughout the mattress. Step-ups feature bio-charcoal cooling foam and 2X the memory foam enhanced pressure relief. All models are crafted with a lofty, quilted top, making them perfect for those who prefer a lifted feel and want rejuvenating sleep each and every night.

*Collected from areas within 50km of coastlines. Plastic bottles collected vary by model ranging from 60 to 100.

Professional delivery and installation is available for every product we sell. We would be happy to coordinate delivery and installation for you.

Extended warranties are usually very inexpensive and can save you thousands in the future. It's simple and inexpensive to purchase extended warranties and one of the smartest ways to protect your investment.

Mattresses can be large, heavy and expensive. You probably don't have the special tools or expertise needed to fix them in a crisis. If you can spare a few thousand dollars without batting an eyelash for new bedding should they break tomorrow, don't buy a warranty. But if you're like most of us, protect yourself by purchasing inexpensive extended warranties when you buy a new product and save yourself big money in the long run.
