Orvis ToughChew ComfortFill-Eco Bolster Nylon Dog Bed - Medium - Orvis' version of tough love for the chewer: This ToughChew ComfortFill-Eco Bolster Dog Bed is constructed with their ultimate chew-resistant fabric. It features a full ripstop nylon base with a bonded microvelvet top layer, designed to guarantee both superior puncture and tear resistance and an extremely soft feel. A sturdy nylon liner adds the final layer of protection. No cording along the seams eliminates chew targets. Even the zipper is tough, constructed of solid brass for long-lasting strength. Orvis' plush and springy ComfortFill-Eco cushion refuses to flatten or clump, no matter how much your dog moves around to get comfortable. And the streamlined bolster creates a sense of security while providing a comfortable place for your dog to lean or rest their head. They introduced their ToughChew beds in 1998. After years of testing, designing, and redesigning, Orvis updated their ToughChew covers in 2018 (their 4th significant evolution of the fabric!). They are now softer than ever, offer an extra layer of protection, and are still backed by their ToughChew guarantee. Nylon cover; polyester fill. Washable. Imported. Medium 40in x 26.5in outside dimensions, dogs 40-60 lbs. Entire bed is machine washable
