Love this bolster wedge for my children's daybed! My children have to share a room, and we recently purchased a daybed with a trundle. This particular daybed is backless. I decided to invest in two of these foam bolster wedges so our kids could sit up more comfortably while watching television in their room. It is quite firm. I just need to find an upholstery fabric and sew a cover for it. It would be nice if there was a solid thick cover for it available on Overstock.com. Anyhow, it is quite sturdy for anyone to sit somewhat more upright.
