About This Item: 1. Orthopedic Support: This pet bed features a dual-layer design with high-density egg-crate foam and a supportive base layer. It evenly distributes weight to relieve pressure on joints and hips, providing lasting comfort ideal for senior, arthritic, or large breed dogs. Note: The sponge foam should not be cleaned directly. 2. U-Shaped Sofa Design: With three sides of bolsters filled with high-resiliency foam (not loose scraps), this durable dog couch forms a secure U-shaped nest. It offers excellent head and neck support, reduces anxiety by creating a cozy environment, and encourages your dog to curl up for deeper, more restful sleep. 3. Waterproof and Washable: Integrated TPU waterproof liner beneath the diamond surface prevents urine, drool, and spills from penetrating the foam core. Please note that the inner lining fully protects the mattress while the soft diamond fleece is not waterproof. The cover is easily removable and machine washable for effortless cleaning and long-lasting hygiene. 4. Certified Comfort and Safety: Crafted with your pet's well-being in mind, this bed includes OEKO-TEX-certified diamond fleece that is gentle on skin and paws, plus CertiPUR-US certified foam for safe and durable support. A sturdy non-slip bottom keeps the bed securely in place during use. 5. Easy Setup and Sizing: Arrives compressed for shipping; simply unbox and allow 24-48 hours for it to fully expand to its original shape. Available in multiple sizes (M, L, XL) to fit small through extra-large breeds comfortably. 6. Additional Features: Includes a carry handle for easy portability wherever your pet settles down to rest.
