US Patent 12011098 Cushion with pressure-relieving bilobate aperture

A cushion assembly for supporting a sitting or reclining person includes a cushion formed with a cushion aperture. The person may suspend a part of their body within the void space of the cushion aperture to avoid contact pressure between the cushion assembly and the suspended body part. An optional cushion insert may be positioned in the cushion aperture. The cushion insert is formed with a bilobate insert aperture and an insert ridge projecting into the insert aperture has a first insert aperture lobe extending away from a first side of the insert ridge and a second insert aperture lobe extending away from a second side of the insert ridge. The cushion insert modifies a size and perimeter shape of the void space in the cushion aperture.
