Designed to help make the most of your available space

The tub chair design is more compact than a traditional armchair but just as comfortable. Sigma and Sigma Plus are available in an armchair and 2-Seater options.

Standard or Plus?

Like many of our sofa ranges, Sigma is available with additional reinforcement and other safety features to make sure it is exactly fit for purpose in challenging environments:

  • Reinforced panels to seat, back and underside for added durability
  • Security fixings used to prevent tampering
  • No piping or staples to minimize self-harm risks
