The Spring Air Etta is the non-flip version of our exclusive and unique Spring Air Cora two-sided flippable mattress

While The Mattress & Sleep Company is known for its specialty of offering tremendously supportive, durable and comfortable two-sided and flippable mattresses, by producing this mattress in a one-sided no-flip version, we can offer a comfortable, supportive Canadian-made mattress at a lower cost.

The Etta may represent a better value for money for part-time use mattresses, come and visit us in the store for good advice which takes account of your own personal context.

If your budget allows, we highly recommend spending a little bit more for the Spring Air Cora two-sided flippable mattress. You'll not only spend less money in the long run, you'll also have a mattress that better maintains its original firmness and support. 

Note: The product photos on this page are of the flippable two-sided Cora model. Both mattresses look the same on top.
