Obasan foundations are handcrafted with the finest Quebec FSC certified wood. They are padded with layers of organic wool and then your choice of an organic knit or organic velour cotton outer fabric. They are available in 4" and 8" heights and must be installed in an existing bed frame or directly on the floor.

2" firm wood slats support your Obasan mattress across its length and width and provide maximum breathability and support. All Essential Foundations are built using nails as opposed to glue which provides a healthy sleep environment.

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.
