Umbra delivered this in 2 days. I ordered The White/Natural shelf for two bathrooms without hesitation based on reviews and am extremely happy with purchase. These are designed well, and are very sturdy.  I did not find any imperfections and they are easy to put together. Brilliant.  The way the anti-tip anchors to wall is unique and virtually invisible, but holds tight. Thoughtful details like stick-on rubber cushions for feet, extra screws, good wall anchors and finish on wood were all put into this item (and I’ve been putting together flat pack furniture for 20 years). The wood appears to me to be white oak with clear stain and tone falls in the middle of teak and birch.
