RH Logic 300 Medium Back Ergonomic Office Chair


RH Logic 300 Medium Back Ergonomic Office Chair

The RH Logic 300 chair is perfect for both remedial and preventative back care solutions, as well as 24/7 use in control rooms

The RH Logic 300 chair can also be enhanced with optional extras including armrests, extra large seat, neckrest and coccyx cut-out seat.
