Big John toilet seats are heavy duty toilet seats that can withstand weight up to 1,200 pounds. Unlike traditional toilet seats that offer three inches of contact surface, the Big John oversized toilet seat provides 5 inches of contact surface, making it more stable and supportive. Its hinges are very strong and the large size toilet seat features non-slip toilet seat bumpers on the bottom. The material is thicker than traditional toilet seats and resists stains. The extra large toilet seat is ideal for people who are larger framed, physically impaired, or those with limited mobility.
