This foldable dog ramp is made from natural solid wood, offering sturdy support and a smooth, burr-free finish. The high-traction fabric carpet with grooves prevents slipping, while the bottom non-slip mat protects floors from scratches. Suitable for older, weak, or arthritic pets, it reduces muscle and joint strain when reaching sofas, beds, or cars. No assembly is required-just take it out of the packaging and use it immediately. When not in use, it folds flat to a height of 4" for easy storage under furniture, in closets, or in cars. Independently safety-tested, the ramp supports pets up to 80 lbs. Adjustable height ranges from 16" to 24" to fit different surfaces. Dimensions - 15.7" W x 32.0" D x 16-24" H
