Unity Seat Specifications

UNITY GENERAL DESCRIPTION

This dynamic product with its adaptable design, has an obvious family relationship with the existing Albany Origin Seat, by mirroring the distinctive features that identify the Albany Origin Seat:

  • Scallop
  • Flexing Back
  • Out trim shape
  • Narrow back, large seat
  • Albany brand as presently shown

The Albany Unity can be surface mounted on concrete, frame mounted, or frame mounted on a tier.

As with the Albany Origin, the Unity is available in nine deep pastel colours, as well as a wide range of custom colours.

The seat has been designed to pass the most demanding standards and comes with a ten year guarantee.

Other general characteristics of the aesthetics of the range that have been maintained, in the design of the Albany Unity are:

  • comfort
  • strength and stability
  • cleanliness
  • abuse resistance

The feel of the aesthetic was identified to be casual not formal, so that it is appealing to all regional geographic groups.

The design forms of the seats maintain the sensuous, curvaceous, feminine (but not delicate) form that the Albany Origin now has.  This aesthetic is essentially different from the industry norm of robust and masculine seating designs.

In addition the seat shall feature:

  •  The seat shall feature a flexing back to provide a balance of patron comfort,  performance and flexibility, whilst maintaining its full strength.

The seat shall incorporate a full lower back to eliminate interference from the feet of the people behind.

  • The seat shall be guaranteed to maintain its original colour with minimal fading for a ten year guarantee period.
  • Perforations in the seat base and back minimize water entrapment and provide ventilation for those hot summer days.
  • Special tamper proof installation fasteners are used to prevent vandalism.
  • The seat has been designed to pass the most demanding standards.
  • The compact dimensions of the seat allow easy access along the rows and aids compliance issues.
  • We can supply special resin packages to provide any specified level of flame retardancy.
  • Two digit seat numbering is provided as standard, other numbering systems can be provided.
  • The products life expectancy is at least 20 years.
  • Our polypropylene plastic formulation has been balanced for colour stability and strength retention in harsh UV conditions.  Little fading will occur over the ten year guarantee period.
