Carole, my name is Jessica with Kohler Customer Service. I am happy to assist with your inquiry. Please work with your local Home Depot for availability of the replacement bumpers. Thank you for choosing Kohler.
Both the lid and seat remain open or up. You can open them together or desperately. And they both slow close when lowering. If your seat is not staying up you most likely didn't install properly.
Multiple options to choose from in the store. Great quality, easy to put on our toilet.
The quick release is operated by opening the screw/bolt covers. Then you simply slide the seat towards the front to remove. It is replaced by reversing these steps.
Yes, it will fit any elongated toilet.
The dimensions of this toilet seat are 18.16 x 14.5 x 1.12 in.
It seens to be the same. The pads fit better
The exact dimensions of the Kohler Cachet Quiet Close Q3 Toilet Seat K-4636 I purchased (and later returned!) is 18 1/16 x 14 3/16. This matched my Kohler elongated toilet. I don't know the dimensions of your Gerber Elongated Toilet so you'll have to review dimensions carefully and decide. An additional caution: I bought and then returned the Kohler K-4636. Other reviews I read turned out to be all too true: it's edges can be uncomfortably sharp depending on how you precisely sit on it (the deal breaker for me). Others reported it's thin, can crack and only has a one year warranty. So even if it's dimensions work, read all the reviews before you purchase.
