Hi Michelle, Our apologies we missed your question earlier! The curved shoe shelves are custom made of acrylic and are adjustable and supported by vertical stanchions on the inside back wall of the cabinetry (it is very slight to see). The wardrobe doors and shelves are tempered glass. My work involved the overall design, details, specifications, wardrobe inventory, and client consult; at which point I sourced a custom cabinetry millworker and specialty finish company to fabricate and manufacturer the cabinetry. Here are some additional views.
