Made from the same fabric worn by astronauts to combat extreme temperature fluctuations, this pet bed helps keep dogs or cats from overheating or getting chills while they sleep. Millions of invisible microcapsules inside the shell absorb excess heat when pets are hot and release heat when they are cold to maintain a comfortable temperature and humidity. The bed is filled with 5" of high-density foam that provides a soft yet supportive surface for pets to nestle. The cover is made from a smooth, soft microsuede. A patented lining inside the bed helps neutralize odors and the cover is removable and washable. Peat or Chocolate.
