The description was in the beginning a bit confusing, since it is valid for three different end lowering mechanisms. It shows only that the toilet seat can be protected against theft, forgetting for use in the private sector! In enclosed plastic bag contains the mounting hardware and on this plastic bag the actual assembly instructions are displayed. Proceed very easily in pictures and quite logical. With a little common sense that creates each in a few minutes!
The toilet seat is made of white thermoset, from heavy and higher quality, you sit comfortable, the seats are designed ergonomically and also something wider. The lowering system works perfectly. Thus, the lid does not pop on the wall, will be also two self-adhesive silicone damper. 10 year warranty on the lowering there, should it even be an issue.
Conclusion: If after taking measurements now know that the Haro Corfu toilet seat fits on his toilet, which meets here a great choice with a great price.
Problem: Have still not received an invoice from the bathroom professional.
