ROLLINGFRAME 52 SOFT - 474 By Alias
Swivel height-adjustable office chair with armrests
Height adjustable chair with arms, with castors and 5-star swivel base with tilting mechanism. Structure made of extruded aluminium profiles and die-cast aluminium elements; seat and back in kvadrat® fabric or in pelle frau® leather. Soft castors.
*** available also with hard / soft breaking castors
The hardness of the spring that governs the tilting mechanism can be adjusted in relation to the users weight.
The collection is rounded off by meetingframe lounge 52: a piston 50 mm lower than usual and a back slanted by 5 degrees converts the chairs into small armchairs, which are even more comfortable when paired with a feetframe ottoman.
The new proportions of the frame 52 collection makes these chairs ideal for informal technical seating, home office and operational office premises.
Frame 52 chairs, available with and without arms, are characterised by a structure made of extruded aluminium sections and die-cast elements in the finishes: chromed, polished, stove enamelled in different colours. Seat and back are made of polyester mesh covered with PVC in many colours; or Kvadrat® fabrics; or Pelle Frau® Color System leather, in a selection of 7 stylish colours. Another option is a polyester mesh coated with PVC with hemp fibre, visually more opaque than the standard version, and with a natural touch.
Frame 52 also comes in a SOFT version, with a cushion upholstered with soft Pelle Frau® Color System leather or Kvadrat® fabric and divided into four sections: two on the seat and two on the back, for enhanced comfort.
The frame 52 & frame soft 52 collections comply with UNI 1335C standard relating to the ergonomic principles and minimal functional requirements of office chairs.
The frame 52 collection was created by analysing the proportions of contemporary seats and the changes that have taken place in the typical construction of the office chair, which has increasingly acquired the connotations of a “workplace”, where different social relations activities and team work activities take place.
To meet these new requirements, starting from the mechanical design of the rollingframe and the meetingframe equipped with the oscillating TILT mechanism, Alias asked Alberto Meda to study a new system of bases and mechanisms which would make it possible to increase the width of the seat by 10%.
The difficulties encountered during the research and development process were mostly due to the physical properties of the elements which were required to support elements of very different sizes, compared to the historic collection, without diminishing the formal lightness that has always characterised this collection.
Based on a new approach developed through careful static analyses, two new bases are now available, 70 cm in diameter, featuring a flat, slim profile, with the thickness close to the limit of the physical strength of the parts, which makes it possible to fit different pistons and create different chairs of different heights.
The handle of the tilting mechanism and the die-cast elements have also been redesigned according to the spirit of the frame project.
With frame 52, Alias and Alberto Meda show how keenly they follow the evolution of product construction and the applicable regulations: the frame chair, one of Alias’ top sellers, has been substantially restyled to conform to new ways of working andnew ways of using the product.
With its elegant proportions, frame 52 is ideally suited for use in an office environment, but it is equally in the world of hospitality and in the private household, where the meetingframe lounge chair finds its ideal location in the relax area of the living-room.
Rollingframe 52 is characterised by a five-star swivel base in die-cast aluminium on casters, and an exterior mantle connecting the outer surface of the 40 mm piston to the centre of the base. The self-aligning swivel chair meetingframe 52, of more compact design, has a four-star base on die-cast aluminium feet.
In either case, the base adopts a tilting mechanism ensuring a higher degree of comfort by making it possible to tilt the seat and the back in sync.
