I love pottery barn and crate and barrel- a majority of their furniture is made with composite (MDF). For example, in your case, if you got a dresser from pottery barn, the top and sides and bottom would be out of wood, but the drawers would be made out of composite. Or veneers over composite. Composite dents easliy and does not hold up over time.
Good point! I have always loved the look of pottery barn furniture..and was sure thats what I'd end up with...but a friend just did a lot of her house from pottery barn and I was stunned that furniture that expensive was composite! That what turned me away...I think what I spent at Thomasville was similar to what I would have spent on Pottery Barn..but much higher quality!
