We remodeled our master bathroom several years ago and decoded on Toto as they had the best rating for their flushing mechanism.  We were at the point where now we needed to replace the seat and since our bathroom is a 50's style black, yellow and white...we decided to try the black seat.
These seats are soft close and VERY durable.  The black was a great buy from the retail from Toto!

Pros: Perfit fit and quality
Cons: none
