Part of the Dream Chaser line, and like the rest of it the cover is reversible — one side sleeps cool, the other sleeps warm, so the same bed works in a Miami August and a January cold snap. Bolstered sides give a dog something to rest a head against, which is what you want for the ones that sleep jammed into a corner. Large, 30" x 27". Top and fill are polyester, the sides and bottom are a cotton-polyester blend. Machine wash cold on gentle, tumble dry low, non-chlorine bleach only.
