All Bath Royale seats are designed and tested to hold 400 pounds. Our Premium and Superior seats and cover (made of polypropylene) may flex, but are guaranteed not to crack, break, or permanently deform.
If you don’t like the feel or flex of polypropylene, we suggest our MasterSuite seat, made of Eurocast®, as an alternative. Eurocast®, is a high-tech polymer that is extremely durable and scratch resistant; it's heavier, harder, and has zero flex. Additionally, MasterSuite bumpers are rubberized (slip-resistant) and strategically placed for increased stability. For customers of above average weight and/or who often sit on the closed lid, MasterSuite is your best choice for maximum support.
