Sewing Cushions
Next up is sewing cushions. Like most of the other work on this project, we did this ourselves. The first part was determining what kind of cushion we wanted to build. Ultimately we decided on a 4 inch firm density foam wrapped with batting and upholstered using Ultraleather.
Because the cushions are custom sizes, we started with a few large sheets of 4 inch foam. The foam gets cut using a serrated knife (I hear an electric knife makes this even easier.) It then gets wrapped with polyester batting. At first I thought the batting needed to be glued on, which is a hassle dealing with spray glue, but after some additional research I found that the easiest way is to staple the edges using a household stapler. It seems counterintuitive, like the staples will poke out, but by virtue of where they are placed and how the upholstery snugly fits you never notice them and they are never felt.
You need to make accommodations for the foam to be put in, which is best accomplished with a zipper. On the sides not visible, I used a backing material that also allows airflow so when you sit on the cushion it does not get a big puff of air trapped in it that slowly escapes. It also should help keep the foam in good shape for longer.
Upholstery is sewn inside out so that the stitching is invisible when completed and turned outward. You can see this in the final pictures. While this is an option, I did not elect to do anything like piping on the edges of the cushions which adds a fair bit of complexity.
The completed assembly is designed to convert into a bed of roughly queen size. When using it we also have a 2 inch memory foam topper. With those together it makes a comfortable bed. We store the memory foam topper in a vacuum seal bag when not in use.
