    High-Quality at a Value Price

    We tried an automated manufacturing process and it worked! The end result? Lower cost and lower price without any impact on quality!

    What does a Sown Cover look like?

    This automated procedure allows us to build the Sierra with lower costs coming from inefficient factory processes. It is possible now to offer a value option without impacting on the quality of raw material.

    The main difference is that when you will receive your mattress, to make it look like a superstar, you will have to hide corners inside the cover.

    Anyway... with blankets, you'll never notice it again! But, you will surely remember all the money you saved on your mattress!
