Manufactured domestically from your large breed experts, Mammoth pioneered the large dog bed for almost three decades. The Lounger is made for the serious spoiled dog. Super sized with an eight inch thick orthopedic density foam mattress, this large dog bed offers options to upgrade to the temperature regulating cooling gel memory foam for added comfort which gives you a five inch orthopedic core with a three inch memory foam top for premium support for your large breed. This is vet recommended providing  optimal support as memory foam by itself is non-supportive and too soft. Like all our large beds, this mattress will support your giant dog with a whooping 300 LB weight rating for the XXL.

The mattress is wrapped in a thick polypropylene cover for protection which is standard. Washing has never been easier and takes less than a minute to remove the cover using a hidden heavy duty YKK zipper that is self repairing.

Comes in luxurious upholstery fabrics, micro suedes, micro velvets and canvas. Click the color tab to see colors available or click here.

If you want a bolster with this type of mattress, please see Mammoth memory foam dog beds.  The XXL oblong is also a great choice for heavy breeds such as Irish Wolfhounds. The large bolster allows for more comfort and a head rest that goes all around the mattress.
