End the night-long hunt for dropped items and restless edges with a seamless mattress gap filler designed for king beds.
- You have three width options—4, 6, or 8 inches—to close wide gaps along the mattress seam and headboard, keeping pillows and belongings from slipping through.
- You’ll enjoy a flatter, more comfortable sleep surface thanks to a resilient 45D foam core that conforms to your mattress contours.
- Your cover uses a silk cotton blended fabric that breathes, feels durable, and is removable for machine washing.
- You can use it for multiple uses—headboard space or mattress extension; note that recovery time depends on placement, and you need to place the filler for 24117 hours to restore it to its original state.
