Flokk RH Logic 400 review

Detailed review of the RH Logic 400 XL by a 6'2" user praising its exceptional seat depth (48-55cm range), adjustability, and build quality, but ultimately returned due to uncomfortably firm seat cushion that caused pressure on sit bones after extended sitting.

Pros

  • Exceptional seat depth (48-55cm) that fully supports long thighs
  • Highly adjustable backrest with height, tilt, and forward tilt options
  • Forward tilt seat pan feature which is rare in ergonomic chairs
  • Breathable fabric with no heat buildup
  • Configurable neckrest and armrests with multiple adjustment options
  • Built to last with solid construction quality

Cons

  • Rock-hard seat cushion (CMHR foam) with no contouring that causes pressure on sit bones
  • Armrests have hard plastic tops that rattle and are uncomfortable
  • Seat height sits higher than standard even at lowest setting due to XL gas lift
  • Limited recline range makes it unsuitable for relaxed leaning
  • Not comfortable for extended sitting sessions despite excellent adjustability
