This black moulded wood toilet seat and lid are manufactured from high quality, responsibly sourced moulded wood and finished in a striking black finish. The seat and lid are made from moulded wood with a Thermoset surface, a production process that involves mixing recycled wood flour with Thermoset material. This technique produces a hard wearing, water resistant toilet seat that won't swell or split. All Bemis 5000 range toilet seats are naturally anti-bacterial. It features the innovative Ultra-Fix technology, proven to stay put even after 30,000 cycles and last 40 times longer than regular toilet seats, keeping your toilet seat secure and preventing loosening. The adjustable plastic hinges are subtle and allow for a snug fit to the pan. This toilet seat has a traditional bottom fixing style, where bolts are fitted from the top and tightened from underneath. Bottom fix seats are NOT suitable for use with wall hung or back to wall toilets. Bemis toilet seats are designed to fit almost any toilet, regardless of style (contemporary, traditional, high rise or short projection). Fittings are included for straightforward installation. Bemis strives to use the best technologies and expertise to improve efficiencies and carbon footprint, making this a very environmentally friendly product. It comes with a 2-year guarantee.
