This type of construction exposes the edges of the frame -- a reveal -- around drawer fronts and doors, great for country and traditional looks.
Pros: Stability. The solid-wood frame is rigid, so cabinet tops, bottoms, sides, and backs can utilize thinner material.
Cons: Smaller openings. The width of frame members reduces the size of drawer and door openings as well as any roll-out accessory options.
This style of cabinet shows a continuous expanse of drawer fronts and doors -- an uncluttered, contemporary look.
Pros: Accessibility and style. Besides their clean, virtually unbroken design, frameless cabinets open up to their full potential so everything's easy to access.
Cons: Tricky to lay out. Because the doors and drawers butt right up against each other, frameless units require door clearances that aren't needed with framed cabinets.
