Constructed of high density molded plastic, it has it's inconsistencies, think incomplete waffles (rationale for 4 star rating).  With that said, this is a NICE product and more importantly, after the sale customer support is fabulous!!!!!  Point of order:  I had several broken pieces and one missing screw.  Called this manufacturer (not Wayfair, as instructed in the packaging) and they responded with flying colors!!!!  Parts where expedited to my home within days (at not cost to me)!  I am now a loyal fan of them!  Thank you Wayfair for an enjoyable transaction.  Looking forward to purchasing more of your products!
