This shelf is originally from IKEA, but definitely on the nicer side of IKEA pieces.
Shelf 16.75” deep 17.55” wide and 63.25” tall (without stand legs)
Stand makes cabinet 5” taller and adds about 3” to the 16.75” front to back length
Two permanent shelves 16”deep x15.75” and two adjustable 15” deep and 15.75” wide (interior of cabinet)
One door (light color) 15.8”x 15” tall
Hardware is removable (obviously would leave screw holes etc if removed)
Used but good condition, very sturdy for a tall & narrow bookshelf -- great for small spaces! Feel free to make an offer.
