When twenty students fill a room, chairs whose seats measure 18 inches suit middle school through adult users. Stackable meeting chairs become a practical planning question when the same rooms must support instruction, meetings, break periods, and storage between uses. This 18-inch seat-height chair is specified for middle school students through adults, giving you a consistent seating height for that portion of your population. A set of 20 lets you plan a room by a known quantity, while the ability to stack five chairs together gives your staff a clear way to consolidate them when the room changes purpose.
Each chair uses a polypropylene seat and back described as flexible and able to wipe clean. Its chrome-colored tubular steel frame is paired with matching leveling glides; these components are identified as supporting a steady, wobble-free chair. A built-in handle on the back supports carrying and mobility as you rearrange seating in classrooms, libraries, breakrooms, or meeting areas. Overall dimensions are 16-inch wide by 21-inch deep by 33 1/2-inch high. The seat height is 18-inch. The dimensions give you a clear basis for planning rows, aisle spacing, and storage locations without relying on estimates. The frame and glides support floor contact, while the polypropylene components give you a wipe-clean surface for routine classroom use.
For your purchasing plan, this configuration comes as a set of 20 chairs, so you can match the quantity to a classroom, library area, breakroom, or other shared room. The 18-inch seat height is specified for middle school students through adults, while the source description notes three sizes for accommodating users from preschool age through adults across a broader school or library setting. When one room must serve more than one function, you can stack the chairs in groups of five for storage between activities. The polypropylene seat and back, tubular steel frame, leveling glides, and back handle keep the decision tied to the components your staff will use and move. You are choosing a measured seating configuration: 16-inch wide, 21-inch deep, 33 1/2-inch high overall, with an 18-inch seat height and 20 chairs in the set.
