Sit back, rest properly and rise with confidence

When standing up from your favourite chair takes two or three goes, or you find yourself dozing off slumped to one side, it's time for a chair that does more of the work. The Cosi Ambassador Medium lifts you gently to your feet and lets you lean right back into a fully supported resting position.

Medium is the middle of three sizes, made for people of around average height and build. Deep layered cushions and a sprung seat make it a chair you'll want to spend the evening in, and it's made here in Britain.

✅ Key Features & Benefits

• Smooth powered rise
  Press a button and the chair lifts and tilts you forward to a standing position, easing the strain on stiff knees, hips and a weak back.

• Tilt-in-space resting
  Rather than just dropping the backrest, the whole seat tips back together, which spreads your weight and eases pressure on your bottom and spine.

• Variable Angle Lift
  The angle of the rise can be adjusted, so the chair can be set to stand you up in the way that feels safest for you.

• Two motors for back and legs
  Raise your feet without lying flat, or sit upright with your legs up — handy if you have swollen ankles or tired legs.

• Waterfall back
  Generous stacked cushions that hug your back and neck, helping you sit comfortably without slipping down.

• Five years' cover
  The frame, mechanisms and electrics are all guaranteed for five years.

• Pleated wings and washable covers
  A classic, smart look for your living room, with arm and headrest covers included.

Colours available

Kilburn Cocoa, Kilburn Mink, Kilburn Oatmeal, Kilburn Plum, Spray Cocoa, Spray Mink, Spray Oatmeal and Spray Plum, plus more than 500 made-to-order fabrics and a leather option.

Who it suits best

• People of average height who struggle to get out of a chair
• Anyone who naps or rests in their chair during the day
• People with swollen legs or ankles who need to raise their feet

Worth knowing before you buy

A riser chair only works well if it fits you: too big and you'll slouch, too small and you'll feel perched. If you're quite petite or quite tall, the Small or Large Ambassador will probably suit you better. And if you don't need the tilting seat, a standard dual-motor riser recliner is a lower-cost option.
