This bolster pillow is built tough! Featuring a heavy-duty ballistic fabric liner that’s significantly stronger than the covers of regular beds, our Tough Ripstop Rectangle Bolster Pillow fill won’t break down or wear out, even under hard use and heavy play. The shredded foam interior is the perfect blend of soft and supportive, making it the perfect place for sleepy pups to rest their heads after a long day. Bolster pillow only, mattress and cover not included. This bolster fill is compatible with the Tough Ripstop™ Rectangle Bolster Dog Bed Cover only. It is durable against normal wear and tear but is not chew- and scratch-resistant on its own and should not be given to a destructive dog when uncovered.
