I was not familiar with "rubber wood" and thought this was going to be some kind of pressed board or composite wood product. I have subsequently learned that rubber wood is a beautiful natural hardwood. I am using this as a sewing cabinet since the only things sold on the market are very expensive and yet cheap looking. This item looks great and is sturdy, roomy and well built.I have purchased and assembled furniture before and must say this was BY FAR the best assembly yet. All of the components were properly aligned and drilled; however the instructions could have been a bit more clear. I am a petite woman and was able to assemble this unit without help (with the exception of attaching the flip down door) in approximately 4 1/2 hours. I am THRILLED with another great purchase from Overstock!
