Quiet Close: This quiet close lid forces a gentle descent guaranteeing that your seat will never slam as you put it down.
Quick Attach: To get you fast on your way to enjoying your new toilet seat, the Quick-Attach Hardware from Kohler makes for fast and secure installation. Simply set the seat with the screws in pre-drilled installation holes, slip a wing-nut underneath and tighten from the top with a screw driver, it’s that easy.

Simply pop open the caps and gently pull the seat forward and you are ready for that detailed cleaning job that has been so difficult in the past.

Product Reviews

Modern Quiet-Close Round Front Toilet Seat with Quick-Release from Cachet Collection 4.5 5 18 19

Falls way short of expectations I bought one to test for a couple of months and liked it so much I bought one for the 2nd BR. After less than a year the first seat no longer closes slowly. I opened it up and found that both "slow closing technology" (this is what Kholer calls it) mechanisms in each end are bad. I guess in the next two months I can expect the other to go bad. I could not just buy the "plungers" (what I call them because they lock the seat and lid together and contain the "slow close technology); I will have to buy (costs tax, & plus shipping and handling) the whole EB Hinge Kit for almost what I paid for the seat. Oh, and the kits are out of stock... that should tell you something. Wouldn't buy it unless you want to spend $ every year for new toilet seats. Their "slow close technology" appears to be faulty.

quiet works great, no more klunking down the toilet seat. July 21, 2011

great toilet seat This was very easy to install and exactly as I ordered. It is fun to close the toilet seat down and have it not slam. I love the quietness of it. Excellent price too! June 19, 2011

Best Invention Ever for Toilet Seat This seat is comfortable, but I bought it simply for the self-closing feature, which is one of the best ideas ever for toilets. Once you have one, you'll want it on all your toilets. April 20, 2011

Quiet at last! Love this toilet seat for the no slam feature! It takes about 10 seconds to close and it makes no noise. Now I want to replace all of our toilet seats. We bought white and although the seat is plastic, it matches our white porcelain toilet perfectly. April 20, 2011

Great Purchase Hubby loves the soft close, works great! April 20, 2011

Great toilet seat We love this! It works beautifully, was easy to install and is comfortable. April 19, 2011

best toilet seat ever love this toilet seat. the quiet close is awsome. i tell everyone in my house that the lid is ALWAYS to be closed. now it's easier than ever. but i really love that the seat snaps off to clean. it's a dream come true - a toilet seat that is easy to clean in the place where it gets the dirtiest. November 30, 2010

Really great service from Faucet Direct. Fast shipping. Seat is nice. Great closing mechanism. Easy to install even for a novice. Only negative is seat arrived with a molding divot on the underside. A manufacturing flaw. I kept the seat anyway since it was on the seat bottom. October 3, 2010
