I have read reports of the mirror glass blackening around the edges of med cabs, too. The solution is to only use water and a microfiber cloth when cleaning them. Never use glass cleaner, most of all! I found a space where a med cab used to be in our half bath, behind the wall mirror. It turns out that there is a wall safe made to fit there, too. I got one and my carpenter made a frame around the back side of the mirror, onto which he put a piano hinge. Since it is near the corner of the room, you cannot see behind to see the hinge and the mirror is only about a half inch off the wall, so it is not too noticeable. My friend with the drug habit has not found it, as far as I know, and the safe is working to hold interesting medications and our cash.

Quality may not be determined by the wood (species?), but I see lots of examples of chairs that are self-destructing after a couple of years (or less) because the wood is brittle (brash), does not have a lot of cohesive strength, has grain runout, knots in stress places, or was made into a chair when too wet and cracks, twists, or splits as it dries. I usually mumble to myself, "Well there's another piece of wood that should have gone to the scrap bin and never put into a chair." Call it "wood" or "how it's put together," the result is it's a little cheaper and a lot worse. Pound for pound, I think chairs take the most abuse of any piece of furniture. We don't normally lean other furniture back on one edge or slide it across the floor when loaded with ten times its own weight. Loosening up is not the end of the world because the joints can be disassembled and reglued, unless some idiot has peppered all the joints with pneumatic nails.

I believe waterworks sells one. We currently have a vintage porcelain sink on metal legs that will be relocated to our basement bath. I was very close to buying a pottery barn vanity, but decided against it after reading some horror stories about their customer service. I was hesitant to make a big purchase and if something went wrong, then have to deal with their service. Have you considered vintage?

You can order Ikea online and pick it up same day from the store. They collect it for you. (It's called "Click and Collect). Not a lot to handle, and good social distancing with this method. Each item has the box size listed online, so you can figure out whether you can fit it in the car. You can buy mattresses, pillows, beds, EVERYTHING. You can return it within a year if you don't like it. Also, if you're not too far away (so it isn't prohibitive), you can get stuff delivered. Get the kids to help you assemble it all!
