Nightstand is solid wood construction. Very happy with it but not with customer service. I have shopped with Wayfair for some time  my overall experience with them has been positive. But when I requested inside shelf measurements they claimed it was unavailable. One rep didnt even understand my request. I feel I should have been offered a discount for purchasing  risk. Should anyone need to know...the inside shelf width is 19.14 in. I use this as a station for my shredder, printer ect. My best guess worked out perfectly. Beautiful piece! Highly recommend!
