Stretchable fit that adapts to different seats: Elastic, stretchable design starts with a diameter of about 30 cm and expands to accommodate larger seats — stretches up to approximately 55–60 cm (about 21.6–23.6 inches). This lets the cover conform to a wide range of toilet seat sizes without bunching or slipping. Broad shape compatibility: Designed to fit common seat profiles — round, Ushape, and Vshape — as long as the seat size is under 55 cm (about 21.6 inches). Use it on toilets with different contours without worrying about fit mismatch. What it solves: Eliminates the need to for multiple seat covers for different toilet styles. The stretchable construction delivers a snug, uniform fit across compatible seats so you get consistent performance and appearance. Easy to use and install: Simply stretch the cover over the seat opening; the elastic edge holds the cover in place for stable use and quick removal when needed.
