Marble top or marble-effect coating: A genuine marble top gives luxury and durability (scratch/heat resistant) but is heavier and costlier. Many stands use a marble-effect laminate/coating on engineered wood to give the look.
Storage configuration: You’ll want a mix of open shelving (for media equipment, decor), and closed cabinets/drawers (for tidy storage). For example: “smooth-glide drawers and open shelving” in a marble-top stand.
Size and support: Make sure the stand is wide enough for your TV and strong enough to carry it (especially if genuine marble top).
