Vitra collaborates with Antonio Citterio on Grand Relax lounge chair

Dezeen promotion: Vitra has collaborated with Italian architect Antonio Citterio to create the "luxurious" Grand Relax reclining chair.

Unveiled at Milan design week, the leather chair is the latest product developed by furniture company Vitra as part of its long standing collaboration with Citterio.

Named Grand Relax, it is designed to offer "outstanding comfort", with an understated, compact and slender form.

"The design of Grand Relax originated with the idea of creating a product in leather," explained Citterio.

"The process is different when you have leather in mind, as opposed to fabric – you can't simply adapt the design of a product conceived with a textile cover to one with leather," he continued.

"The idea was then to combine an external structural shell with very soft leather-covered cushions on top. Compared to the Grand Repos lounge chair, Grand Relax is smaller – and more importantly, has loose cushions," he added.

The reclining function is designed to adapt to the user but can be manually controlled

Vitra and Citterio designed the chair with thin cushions that slot into its low-slung body.

Combined with long armrests and tapering backrest, it is designed to create a relaxing feeling when the user sits down.

Grand Relax is also fitted with a mechanism that absorbs the bodyweight of the sitter, and in turn shifts the chair into a reclined position. The seat and backrest move independently to adapt to their user.

To manually control this mechanism, two levers are concealed either side of the seat.

While one of them adjusts the resistance of the mechanism, the other enables the user to lock the back in any angle.

The chair sits atop a four-star base, which is available in either polished or powder-coated aluminium, and allows the lounge chair to pivot by 360 degrees.

It is complete with a height-adjustable neck cushion, and a matching ottoman for use as a footrest or additional seating.
