The back is 50 inches, so it’s further lengthy and offers most protection. A reversible Sherpa Sofa Slipcover, two appears in one. Super soft Sherpa face to heat up reversed to a brushed microfiber to cool off. Added options of waterproof and facet elastic covered straps to keep the protector securely in place. I purchased it thinking he want to relaxation his head on the bolster and he does. However the material is not appropriate for pets and their toenails.
