This is our second bidet seat. The first one worked well, but was not well made and kept cracking until it began to pinch (OUCH!) after 5 years. One of the users of this seat weighs over 300 pounds, so we suspected that was the problem. 

I called Bidet Plus (our vendor), and they confirmed that our old seat was only rated for 250 lbs. They recommended this one which does appear to be much more solid. It is made of ABF rather than the polypropylene found on our previous seat. 

This seat installed easily (about 15 mins), and has worked flawlessly in the week we've had it. The remote and the instructions were somewhat confusing. Also, a word to the wise, we ordered the beige hoping it was about the same color as Kohler biscuit, American Standard linen, and Toto sedona beige. But it is darker, closer in color to Kohler almond and American Standard bone. We decided to use it anyway, but I include it here in hopes this information will help others.
