We were experimenting with how to make a mattress from old bedsheets. One idea we came up with was to cut up the sheets and sew long tubes and fill them loosely with naturally flame resistant buckwheat hulls. Once we had a collection of these tubes we began to connect them by linking them in circles, almost like chain mail. The result was a thick, comfy futon like structure.
I snapped a photo to remind myself to pick up this project again when I had more time.
Next, we tried another method using bedsheets filled with hemp hulls to make your own mattress. It was easier as no sewing was involved! You can see our step by step Instructable showing how we made our prototype here.
The reason for this diversion was that we wanted to create a DIY mattress that anyone could make. The futon concept above would require a sewing machine or hours of hand sewing. Also, buckwheat hulls and hemp hulls differ quite a bit as a mattress filling.
Here at Open Your Eyes Bedding we often get asked, “Why can’t I take a mattress cover and simply fill it with buckwheat hulls? It seems like it would work, but we have tried and it does not. The reason is that the hulls slide to the side of your body as you sleep at a fast rate and they keep sliding. By morning, you are left laying on the board under your mattress.
The solution would be is to pack in more hulls, but this makes the mattress too firm. We believe there may be a solution to make this work. Perhaps using heavy stretch denim and then overfilling the case with buckwheat hulls. There would need to be a good balance between containing the buckwheat hulls while still giving them room to move and contour to your body as you sleep.
When we discovered hemp hulls, we knew we needed to try the one vessel concept again. Hemp hulls are coarser than buckwheat hulls so they do not slide as well. It worked surprisingly well! The surface it creates feels like a sandy beach. The only caveat is that there needs to be a soft base placed under the hull filled sheet to give it just a bit more give. So far we are happy to report the sand mattress concept is a definite win and we hope this can be added to the ranks of our DIY mattress kits soon!
We do currently sell bulk hemp hulls (aka Hemp sand) here for those who want to try their own DIY sand mattress prototype!
