If seat depth is too deep, which issue can occur?

• A. Pressure at popliteal fold
• B. Improved circulation
• C. Improved postural stability
• D. Reduced risk of skin issues

Answer: (A)

When seating depth is too deep, the edge of the chair sits under the thigh and presses into the tissue behind the knee—the popliteal fold. This brings direct pressure into that soft area, which can compress underlying vessels and nerves and hinder venous return, leading to numbness, discomfort, or skin breakdown in that region. The other outcomes listed wouldn’t happen with excessive depth: it wouldn’t improve circulation, posture, or skin protection—in fact, it tends to worsen circulation, weaken postural support, and raise the risk of skin issues where the pressure is applied.
