Description
iRest Grandease (A550) is the first model in the iRest family with an innovative 4D massage system. It also features the remarkable iOpen split guide track, which gives a wider choice of chair positions, better body stretching and a better fit of the massage mechanism to the natural shape of the spine.
THIS IS WHERE 4D BEGINS
The first model in the iRest series with a 4D mechanism. The massage works in three planes and, in addition, once a massage technique is selected the massage rollers speed up and slow down at pre-programmed moments (tempo is the fourth dimension of the massage), which strengthens the feeling of being massaged by a real massage therapist.

IOPEN AND STRETCHING
The massage mechanism travels along the body on a specially designed split iOpen guide track. This lets the mechanism adapt better to the natural shape of the spine while also providing a full-body stretch. It is like a two-in-one: you get the best benefits of Zero Gravity while keeping the advantages and possibilities of a flat position.

CONTROL SYSTEM AND PROGRAMS
The chair has an intuitive remote control as well as a handy phone holder. This model also has a voice control function that lets you operate the chair with specific voice commands.
18 automatic programs
11 massage techniques
Massage coverage: full body, spot or selected area.

AIRBAG MASSAGE
34 airbags precisely target the areas that need relief, tense muscles relax and comfort is restored. They work by inflating and deflating air cells that press on selected points of the body. Stress and tension leave the body, leaving a deep sense of calm and inner peace.

LEG MASSAGE
Thanks to the synergy of three massage rollers with 5-level intensity adjustment and airbags, the massage brings much-needed relief to the legs after a long, hard day. During the massage the lower leg and foot muscles relax and feel light again. The electrically extending footrest adjusts to your height and foot size, ensuring real comfort during the massage session.

SL-TRACK
SL-track technology lets the massage mechanism adapt perfectly to the natural shape of the spine, delivering a comfortable massage that starts at the neck and gently descends to the upper thighs, covering every centimetre of the body.

ZERO WALL
The Zero Wall function is the key to making the most of space and comfort. It allows the massage chair to be placed close to a wall, saving valuable space at home. Zero Wall means freedom and functionality, making relaxation even more accessible, especially where space is limited.

HEATING
Thanks to innovative graphene mat heating technology, the waist and back areas receive a gentle, comfortable wave of warmth. The heating function enhances the feeling of relaxation and lets the muscles warm up, which increases the effectiveness of the massage.

BLUETOOTH SPEAKERS
Built-in speakers take relaxation to a higher level. Thanks to Bluetooth technology you can connect your favourite device and enjoy music that enhances the therapeutic effect of the massage. The chair also has a USB charger.

DESIGN
Available in black-graphite or sand, the iRest Grandease radiates modern charm. Its elegant design blends well with a wide range of settings – from minimalist interiors to spacious lofts. It is a massage chair that not only delivers a comfortable massage but also serves as a feature of the room. Its clean lines and solid construction become an integral part of a contemporary interior.
