Question: Does the lift up top attach to a lift off frame that goes on top of the trash bin?
Document: The wood top is warping badly from the moisture inside the container. I spent a good deal of money to have it stained, rubbed, stained rubbed a total of 5 times./  It is a disgrace. I am ever so sorry to have made this purchase. It is a trash can for the kitchen after all. Coffee grounds and some citrus peels should not cause this kind of problem.
The quality of this wooden trash can is very good and solid, no press board material. You will love it after your stain job has been completed. All friends who saw the can are wondering where did I get it.
I have had this product a number of months now. Generally, I found it to be a good deal. I have yet to finish off the Trash Can with stain, paint or vanish. The lid has shown some signs of warping. Had I painted or stained and varnished this product, maybe the warping may not have occurred. I did not expect this to happen. The lid appears to be curving up on the side opposite the hinged side of the lid.
Wish it were bigger, and the lid doesn't stay on when you open it, unless it's backed up to a wall or cabinet. The quality is great, but wish it were bigger. When a bag is full, suction makes it very difficult to get the full bags out.
This comes raw sanded wood, light wood like the picture. I gave mine a light sanding inside and out, and stained it 'Worn Oak', then used an aerosol can to laquor it, with a couple of layers of semi-gloss clear laquor. It looks like it fits in perfectly, in my Adobe painted kitchen.
Otherwise, I still like the product in general.
Nice quality. No exposed connectors. All screws except the hinges are hidden inside the unit. It does come ready to finish. It's just a touch smaller than I would have liked for a tall kitchen garbage bag holder (I'd have liked it to at least 1" wider), but it's still very acceptable.
I took off the hinges to make finishing easy, but other than that it was pretty much ready to finish. I did wet sand it before staining, though, out of caution.I'd definitely get this again.
Good solid and attractive. So much better than those plastic things. It will do the job. Yah, solid Amish craftmanship.
Answer: Yes the lid and the upper frame are all one piece.  Goes together nicely.  A little aside here I will share with you.  I have a large 85lb lab and occasionally he takes it into his mind that umm!  something smells good in there.  I have come home at lest 4 times to find it in the middle of the kitchen floor with all the contents in the livingroom.  Except for the goodies he and the little dog enjoyed until I came home, that is!   The bottom line here is that the box is very well made and had been rerighted and no one knows the difference unless they look at the teeth marks on the lid. Gives it character.       I say enjoy it.
