Rated 3.9 out of 5 by 157 reviewers.
Rated 1.0 out of 5.0 by Manufacturing defect likely causing cracks This is the second time this seat has cracked (in the same location) with less than 2 years of use and I have found that it is defective. My husband is 140lbs and I am 105lbs - we are not big people. I went to HD to replace and having inspected 3 boxes, there is a hairline ridge/fissure from manufacturing (same position) that you can see and feel with your fingers and is likely causing these cracks. The floor person also commented that this is a problem. Surprisingly, the sample model that customers can look at does not have the fissure and she indicated that those were different b/c the companies know that they get banged around while testing. This is only happening in the round toilet seats since the other 2 Kohler toilets have elongated seats and we have not experienced this problem. I ended up buying the cheaper Brevia, but I'm disappointed that I'm unable to buy the Cachet w/o worrying about it breaking again. In reading reviews from other sellers, it doesn't appear that I'm the only customer this is happening to. I really expected more from this brand. September 25, 2015
Rated 5.0 out of 5.0 by Best choice ever for toilet seat Very easily installed, and is a quiet closing seat. September 23, 2015
Rated 4.0 out of 5.0 by From Wood to Plastic - Sceptic I always purchased wooden toilet seats because they were sturdy. After having the wood start to separate and peel away from urine ( I have all boys) and having to replace the seats over and over I decided to replace with a plastic soft close toilet seat. I got the best of the best, price was a little high but I believe now having it for some time that it might just be worth it. Sits nice, closes quietly, and cleans easy. August 25, 2015
Rated 5.0 out of 5.0 by Cachet Quiet close round closed front toilet seat The toilet eat was easy to install and the quiet close feature works well. Easy to remove and clean. Very satisfied with the purchase. September 1, 2015
Rated 5.0 out of 5.0 by New Kohler seat Although a bit pricey, the ease of installation, the easy clean feature, in addition to being a no slam model made this replacement seat a wise choice. Hope it holds up better than the original Kohler seat. August 25, 2015
Rated 2.0 out of 5.0 by Not necessarily the best product! Because of the easy removal design, the seat will NEVER be 100% tight and will wiggle on the bowl. It was very expensive. Do like the no slam or no crash feature. June 9, 2015
Rated 5.0 out of 5.0 by Good purchase We have enjoyed using this product and would recommend it to anyone. It is a sturdy, well-constructed toilet seat and one that will last a long time. August 11, 2015
Rated 1.0 out of 5.0 by Broken within one month I had this seat for just under a month when the fragile plastic clips cracked. Since this is a quick-release seat, it has two sets of jaws/clips that grab onto the hardware that is screwed onto the toilet. The problem is that these plastic jaws are extremely brittle and fragile. The left side cracked within two weeks, and the right side cracked within a month. It was very easy to install, but another problem that I had was that it never felt "solid" because of the weak hinge clips. It made lots of creaking/squeaking noised when sat on. The slow closing feature was nice, but not as fluid as the seat that I just purchased to replace. (from a different manufacturer) Also, the new seat that I have (which I won't mention due to the review guidelines) has a far superior quick release mounting system. Honestly, I can't believe that the fragile brittle seat mounting clips got past research and development. If you read the reviews, you will notice that I'm not the only one with the cracking problem. Anyway, I should have saved the box and receipt, but I didn't think I had to, so it's my loss. Save yourself the trouble and look at the quick release mounts in the store. It will be obvious which brand you should get. January 6, 2013
