Orthopedic seating cushion

Optimal posture

The inner structure of the Symbia 2.5" includes an angle that provokes a front rotation of the pelvis which helps to restore the natural lower back curvature.

Pressure reduction

A seated position causes a lot of pressure on the sit bones. The design of these posture cushions helps reduce the weight effect while increasing comfort level.

Stress decrease

The Symbia 2.5" design balances the use of muscles and joints by mixing comfort with calculated body repositioning.

Comfortable texture

Our high resilience Velva structure combined with our cooling gel-infused memory foam provides a comfortable feel making adaptation easy and fast.

General Availability Advice

The Mattress & Sleep Company is a family owned and operated Canadian retailer who specializes 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 example, popular Ergomotion adjustable beds and Berkeley Ergonomics mattresses are regularly stocked in Twin XL, Queen and King.

At any given moment, we have thousands of items in stock. 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.
