Dual-sided construction lets your pet use this cooling gel memory foam pet bed across seasons, with one surface that helps diffuse body heat and a soft short plush side for cooler weather. A 7-in thick high-density foam base supports joints and helps align the spine so pets can rest more comfortably. The 3-sided bolster creates raised edges that let dogs brace their back or rest their head while still having an open entry. Sized for most small to medium dogs, this bed has a non-slip bottom that helps keep it in place, and a removable zippered cover that can be taken off for washing to simplify cleaning. Allow 24-48 hours after unpacking for the pet couch to fully expand before use.
