Funny you should mention this. Just yesterday my wife and I went to the local Ikea to pick up some bookcases. I was originally just going to buy a bunch of the Billy bookcases; we have a few and know their limitations.

But then I noticed they had a much better series called the Hemnes made with actual solid wood shelves and legs so you can route power cords and clean under them. Nice.

So instead of a bunch of Billy's for $70 each I ended up with a bunch of Hemnes' for $350 each. We'll see if it's worth it when they get delivered tomorrow.

Bought four Hemnes last year for my sitting room library and various pieces of molded hardwood for a kick board and fascia. Finished up as a single fairly solid built-in bookcase the full length of one wall. The legs allowed for passing wires under (accessible via the removable bottom shelf) and up behind so it can have lighting.

Hemnes is a municipality in Norway. 10 minute drive from where I grew up.
