Wedge pillows also are perfect for elevating the feet above heart level while lying down. While low foam wedge support pillows are readily available in stores, pillows with higher wedges are not as easy to find. By purchasing upholstery foam, you can make custom pillows to suit your needs.

Tips and warnings

  • If you cannot find a very thick single piece of foam, stack one or more pieces of thinner foam and hand sew around the edges to keep the pieces together.
  • Many fabric stores carry foam in a variety of widths. Also search online for "upholstery foam."
