This Scruffs & Tramps Bolster Ortho dog mattress is part of Scruffs\' MEMORY series of orthopaedic dog beds with memory foam. They are perfectly suitable for older dogs, larger breeds or pets that require more support for their joints, back or body. The dog bed is covered with a luxurious plush outer cover. It is also filled with crumb memory foam, and these dense particles mould to the dog\'s shape, offering an ultimate level of support. A water-resistant inner liner protects the bed\'s memory fill against the ingress of water and odour.
