This new Bemis Shell Toilet seat keeps all the classic features of the original seat:

• Moulded wood with soft scalloped edges on the lid
• STA-TITE fittings so your seat STAYS TIGHT to the pan

AND then adds these two beauties:

• Soft Closing  - no more slams
• "Take Off" hinges - twist to unlock the hinges and lift the seat off for easy cleaning!

To be honest, the last one is my favourite.  No more wrapping a Flash wipe around your finger to clean around the hinges!  Brilliant!
