What does 'tight seat' and 'tight back' mean in commercial lounge seating?

A tight seat (T-seat or cushion-free seat) means the seat surface is fully upholstered fabric stretched tightly over the frame and foam — there is no separate loose cushion. A tight back has the same construction on the back of the chair. Tight seat/back construction is extremely common in commercial and hospitality lounge seating because: it is more durable (no cushion to shift, flatten, or fall off); easier to clean (flat, sealed surface with no cushion gaps); and retains its appearance longer under heavy use. Loose-cushion construction is softer-looking but requires more maintenance (refluffing, repositioning). For high-traffic commercial environments, tight seat/tight back is the preferred specification.
