We call this dog bed the "cuddler" for a reason: the soft, plush sleeping area is surrounded by a three-sided cushioned bolster for extra support and nesting coziness. Center pillow cotton-blend side: 57% cotton, 43% recycled polyester twill. Denim: 57% cotton, 43% recycled polyester. Bolster and pillow insert: Polyester fiber fill. Fleece: 70% polyester, 30% sherpa fleece. Cover is machine wash and dry; insert is spot clean only. Center pillow is cotton blend on one side; fleece on the other for double the comfort. Features three bolstered sides, with a lowered front entry for easy access. Comfortable, supportive and more sustainable: denim fabric is made from 43% recycled polyester. Minor assembly required. Great for dogs who like to nest or burrow. Bed and pillow covers remove for easy washing. Rectangular shape also provides extra space for stretching out - and fits well in room corners. Assembled in the USA with imported parts. Premium Cuddler Dog Bed Burlap Extra Large L.L.Bean
