A current classic changes color. Bruno Rainaldi's popular shelving has undergone a change, from grey to white. You may remember Andreas's shelf from his house tour last year. In his mostly white space, the dark color looks great; it's a nice bit of contrast. Part of the appeal of the Sapien design is that the books take centerstage and the actual shelving disappears, so white might be an interesting choice as well.
Available at Design Within Reach, the bookcase in white lacquer finish on steel is $208. for the short, $298. for the tall.
If you prefer the original dark grey, the short is now $148, tall $278. Multi-unit sales are discounted, as well.
