This series of pet stairs comes in 3-step, 4-step and 5-step optional sizes to match different furniture heights such as beds, sofas and car seats. Designed with flat wide treads, they offer stable, low-strain climbing for small pets, senior animals, injured pups and short-legged breeds to avoid joint damage from jumping. The solid high-density foam inner core delivers reliable load-bearing performance and stays free of sinking or deformation after long daily use. Textured non-slip fabric covers each step surface to boost paw friction and prevent slipping during movement. A full zippered outer cover can be completely removed and machine washed for quick cleanup of pet hair and stains. Featuring a split splicing structure, the stairs require zero tools for fast assembly within minutes, ready to use right after setup. The neutral matte appearance blends naturally with all indoor decor styles, bringing safe and convenient mobility support for furry companions.
