Green Sleep mattresses feature the same high purity, high quality natural and organic materials that Green Sleep has become known for in Europe. These premium mattresses are truly unique in design, featuring lush outer covers made from soft-to-the-touch velour or pleasantly thick stretch knits, lined with pure Texel virgin wool, and inner covers for added stability. Each Greensleep mattress is made to last a long time, thanks to their high standards in design and manufacturing. Handmade in Canada with a 20 year warranty.
