A couple years ago, we wrote about buckwheat hull mattress toppers from Open Your Eyes Bedding, which are a great natural solution for neck and back pain. Now, the company has expanded its line to include DIY (no-sew!) mattress kits using the same environmentally friendly filling.

You can choose from the Twist DIY Mattress Kit in cotton canvas or soft woven cotton, or the Twist Easy DIY Mattress Kit, which features a different pattern. Both kits come with e-book instructions and a yardage of fabric covering that you'll fill, tie, and twist to form your mattress — all the way up to a king size! (Buckwheat and millet hulls are sold separately and are available from the site).

For the ambitious DIYer with a sewing machine, you can even buy the instructions and templates to make a mattress using your own materials and filling.

Check out Open Your Eyes Bedding for more info (the ordering process is a tad confusing; click on each product from the front page, not from the "Order" page).
