Mattress cushion with securement feature |
摘要 |
A mattress supplement comprised of resilient material is substantially covered with support projections except for at least one marginal edge thereof. The marginal edge is adapted to compressively receive a sheet fitted thereto. The compression of the marginal edge permits the sheet to be secured to a mattress on which the mattress supplement is placed, instead of being pushed off thereof by the support projections.
