I love the wool products Bio Sleep is offering. I have both a king size pillow and this mattress topper from them. It's huge out of the box, it's stood up well to a month of use, and it smells like sheep. I purchased this for my dorm bed, but I've been using it for the last month on my Full size bed anyway. I like it so much I wish I'd thought to buy one before.
These are also excellently priced. Comparable products I've researched have always been considerably more expensive, so I never made the leap until I saw these products on Great Offer Stock. I'd recommend them to anyone.
I take one star off because while I love the products, I don't love the advertising. The content tag on this product says "100% Organic Cotton, 100% Pure Grow Wool." The Pure Grow Wool of the pacific northwest is 'eco,' sustainable, humanly produced, and most other things I'd want from an organic product, but it's not actually certified organic, at least that I can find. Bio Sleep's description "100-percent organic Eco-Valley wool" raises eyebrows. They should be clearer in their advertising.
