Back injuries and discomfort can be prevented through good posture. The lower area of the chair should provide full contact to support your lower back. Without this support, pressure is put on the lower back and travels all the way to the shoulders. Select a back cushion that encourages the 2 to 4 finger space between seat and back of knees. Some chairs are too deep and need a thicker cushion while other seats are too narrow, requiring a thinner back cushion.

Using a back or seat cushion takes the discomfort out of dining room seating, bucket seats in cars and metal folding chairs or an improperly sized ergonomic chairs. Ergo Works offers a wide selection of seat and back cushions to choose from for home, office or travel.
