- 1. Sponge bed gap filler: made from high-density 40D sponge, this filler is highly resilient and maintains its shape. It provides comfortable support and does not collapse under regular use. - 2. Close the gap: fills the space between the mattress and the headboard, wall, or footboard. Prevents pillows, pets, and toys from slipping off the bed. - 3. Easy to cut: can be cut freely to the desired length and angle to fit your bed setup. It may ship under compression; it will not warp and will fully expand within 24 to 48 hours. - 4. Wide application: sponge strips offer comfort and support and are easy to use. Suitable for dormitories, bed seams, and patchwork beds. - Use scenarios: - Dormitories: fill the gap between mattress and headboard to keep pillows from slipping and improve sleeping alignment. - Beds with seams or patchwork frames: fill gaps along seams for a smoother sleeping surface and to prevent items from getting lost between mattress and frame. - Rooms with tight headboard gaps: close gaps along the headboard wall to keep pillows, toys, or small items from falling off the bed.
