Plush, even loft comes from giving the fill enough room to expand and enough structure to stay where it belongs. The Fiberbed Down Alternative Fiberbed uses 12-inch baffle boxes separated by 3-inch walls, creating generous chambers that allow the GRS-certified polyester fill to loft while helping maintain consistent distribution across the sleep surface. Unlike a sewn-through construction, the baffle-box design creates space between the shell layers for a fuller, more substantial profile without the uneven feel that can develop when fill migrates between stitched sections. A 3-inch gusset extends that generous profile to the edges, while the 195 thread count cotton shell provides a breathable surface beneath the sheets. The result is a soft, substantial layer with the plush feel of a featherbed and the practical comfort of a down alternative.
