Ear-shaped headboards at both ends give small pets a firm surface to lean against while they rest, and the surrounding guardrails help keep bedding from slipping off the sleeping area. The elevated legs raise the pet bed off the floor to promote airflow and reduce contact with cold surfaces. A 21-in length keeps the frame compact enough for different rooms while still accommodating bedding up to 20 x 16 in, so you can choose suitable cushions or pads. Made from P2 grade MDF and particle board with smooth, curved corners, it supports up to 44 lbs for puppies, cats, rabbits or guinea pigs.
