The shelf is wood as advertised but is not worth the price. It came in the box still tacky and off gassing from the stain that was used. Is darker then what was expected. The “reinforcement” beams on the back are just decorative and are actually 4 small pieces of metal not the two long beams they appear to be in the picture. The stain used does not give a shine to it like a finished piece would have it is more matte finished. For what it is it is very over priced.
