I've got wooden IKEA shelves in my shed and they take serious abuse of big heavy tools, lawn mowers, car batteries, paint cans etc being non-carefully put/clattered away and they're holding up 100% after years. I can't imagine any normal shelves needing to be "well made" to support a few magazines and a toy model Porsche?
Or is this just a "because I am rich and want you to know how rich I am" type thing?
Tables are really well made. So are the bookshelves. They are sturdy, high quality and withstand to abuse.
There are high quality items, and there are fine and high quality items. What he uses the latter.
Take an example. He uses fountain pens (so do I). Montblanc inks, a Lamy 2000. They are not expensive for what they are, yet they are fine instruments. They are made with care. I have tons of inks, yet Montblanc and a couple of brands really stand out in reliability, writing comfort and color quality. Same for L2000. It’s a very understated but a completely handmade thing, with great attention to detail. It’s even too much pen for that money.
The furniture he uses are the same. Understated, yet fine. It’s not there to make a statement, but to be enjoyed by their owner. I share the same sentiment. I do not buy anything to impress anyone, but to enjoy.
Nobody, sans my wife sees my most prized possessions. I got them to use and enjoy, that’s all.
IKEA doesn't actually make any modular wall shelves like that anymore, after discontinuing the SVALNÄS. For a wall mounted shelf on a budget you could go for the Elfa system or the Fasttrack one.
The chairs in front of the desk might be a pair of Vitsoe 620 Chair Programme.
