The Obasan 9" Essential mattress is a beautifully handcrafted mattress that incorporates the highest quality, breathable, 100% certified organic materials. It provides an incredibly comfortable, dry, cool sleep for one or two sleep partners, based on individual tailoring for individual sleepers.
The Obasan Adjustable Core System provides highly flexible support layers. Cores can be purchased separately, which ensures the mattress can be altered at any given time. The 9" Essential mattress is available with a soft, medium or firm middle layer. Queen and king mattresses feature a middle layer that is split, allowing each individual sleeper to choose their own firmness.
The 9" Essential mattress is Obasan's most luxurious Essential collection adult mattress and includes a built-in topper that provides body contouring and pressure relief. It also comes with a removable cover that can be easily spot cleaned and aired out. Obasan does not use harmful, fire retardant chemicals. Instead, Obasan uses organic wool that is quilted into the cover and is an all-natural fire barrier.
The 9" Essential mattress is an excellent choice for parents as a one-time investment in their child's sleep. Out-of-town guests will sleep well on an 8" Essential mattress in your guest room.
Recommended maximum weight per sleeper of approximately 250lbs (110 kg).

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.
