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
