Quadra PLUS armchair & sofas

Quadra PLUS Armchair and Sofas are specifically designed for environments where stability, durability, and resistance to tampering or misuse are essential.

  • Plywood-reinforced frame provides exceptional stability and strength for daily use
  • Removable seat cushions allow for easy cleaning and maintenance
  • Fully enclosed base eliminates the possibility of concealment

The Quadra PLUS range is well-suited for facilities with enhanced safety requirements, such as psychiatric care, correctional institutions, and youth care facilities.

Carcass made from a mix of particle board and plywood with solid beech wood feet. Strong plywood reinforcement offers excellent levels of durability and strength. Cushioned areas made from fire retardant, CMHR (combustion modified high resilience) foam is safe for both users and staff.

All models are completely free from stitched piping and staples — a construction method that minimizes the risk of self-harm.

The furniture’s relatively high weight ensures it remains securely in place and is difficult to move, overturn, or misuse in ways that could pose harm to people or surroundings.

The furniture can be customized to match specific interior design schemes through the selection of fabrics and colors. We recommend Aston or Highland fabrics for optimal durability and visual appeal.

Recommended for use in patient rooms, communal areas, and shared living spaces.
