A proven and dependable natural latex mattress that has been tested time and again. This is a very long lasting mattress that has proven itself in Fire Departments where edge support is put to the test under heavy use. The two-sided Whidbey is very durable, with its long lasting 85 density core and 1″ soy based poly foam quilt. This model, built with a Botanicore™ natural latex core, should positively react to wear issues such as having guests sitting on the bed, let alone sleeping on its comfortable surfaces. We have added side handles making it easier to flip over and/or rotate from end to end.
