Give Your Furry Friend a Soft Ramp, Easily Climb to Their Favorite Place! Our 4-tier foam dog ramp measures 28.5'' x 16'' x 20'' (L x W x H) and features 4 steps, which can be a good helper for your lovely pets to get up and down the higher places. Compared to normal dog ladders, our dog ramp is supported by high-density sponges, which provide ultra-soft touch while quickly recovering its shape for better support. More than that, the gentle slope design is also good for pets’ joints while effectively reducing the strain on the legs from constantly jumping up and down. The surface adopts premium corduroy and suede fabric, and the bottom is designed with silicone paw prints to improve friction, so dogs would not slip when moving on it. The ramp’s cover is equipped with zippers that allow you to detach the cover for cleaning, and it is machine washable. Special Note: For convenient transportation and carrying, the dog ramp adopts vacuum compression packaging, and it may take some time (48 hours or more, depending on the ambient temperature) to completely rebound.
