Another good bolster dog bed you can buy is the K&H Ortho Bolster Sleeper Pet Bed.
The inner foam is made of orthopedic foam used in medical facilities, so it’s perfect for pets that tend to be in pain or have trouble with stiffness. The foam is a nice three inches of thickness and the sleeping surface is made of soft micro fleece that dogs love to sleep on.
The bolster runs nearly the entire length of bed except for a small area where the dog can step onto the bed. The bolster is filled with premium polyfil made from recycled plastic bottles.
You can purchase the bed in either brown or gray colors and the liners and cover are removable for washing convenience. The bed is available in sizes small, medium, large or extra-large.
