Orthopedic wedge cushion

Full back support

Joint and muscle pains are often caused by improper sleeping positions. Designed by specialists, the Symbia 18° and 23° relieve pain and pressure.

Digestive efficiency

Digestion and sleep are not a good mix. The Symbia 18° and 23° inclination facilitates digestion and reduces gastric reflux.

Clear breathing

Breathing plays a crucial role in the quality of sleep. The unique posture provided by this cushion liberates the chest, clears the airways and eases deep breathing.

Pleasant relaxation

Reading or watching TV in bed are privileged relaxation moments. A stable and comfortable position will provide the correct posture.

General Availability Advice

The Mattress & Sleep Company is a family owned and operated Canadian retailer. We specialize in high-quality bedding, bath and mattresses from Canada, Europe and the USA. Our vast selection makes it impossible to stock everything. For this reason, our website does not offer real-time inventory availability as many of our products are made to order.

Please read the availability details above as we do make an effort to draw attention to products which are typically in stock in our Calgary, Edmonton and Sherwood Park stores and warehouses.

For time-sensitive needs, please give us a call Toll-Free on 1 (877) 750-1212 or Send us a Message and we will be delighted to help.
