I've cleaned with bleach and haven't had any discoloration. It's made of plastic.
When it is time to remove the hardware please use wrench on the reminder part of the nut. When it loosen you can unscrew it from the bolt. Please also know that if the new replacement seat has the same hinge, you can keep hardware from old seat and just replace with new one, just like you remove the seat for cleaning and putting back . Please contact our customer service at firstname.lastname@example.org if you have any additional inquiries.
My roommate had trouble so a handyman for our complex put it on. He apparently had some trouble as well. But the seat was worth the trouble because it was the most comfortable seat I have ever used.
Why would you put a toilet seat in your dishwasher?
Get the adjustable 1
Toilet seats typically come in two shapes; round and elongated. So you need to look at the shape of your toilet "base" to determine the shape.
There is no adjustment for the slow-close function.
You can unscrew the locking nuts where it attaches to the toilet and slide it so it is more centered. There’s not much adjustment room though. Once you get it close to where you want it, hold it in place and re-tighten the locking nuts a little on each side until they’re both tight. Tightening one down completely then doing the other will cause it to shift and make the seat uneven.
While you could sit on it with the lid closed, I've started sitting elsewhere when I need a quick "chair." At 175lb, I can feel the lid give and bow beneath me when I sit down.
I measure the inside opening at 10 1/4" front to back and 8 1/4" side to side at the widest.
