Orevive SpineEase for your office chair

• Sit right back so your hips touch the back of the chair
• Place the cushion in the small of your back
• Adjust the height until the curve feels supportive, not pushy
• Keep your feet flat and screen at eye level
• Switch on and start gentle

Australian workplace health guidance recommends changing posture often and breaking up sitting time. A cushion can make sitting more comfortable, but standing up, walking and stretching through the day are what help most.

On ergonomic chairs with strong built-in lumbar support, you may need to lower that support first. Gaming chairs with a lumbar pillow can swap the pillow for SpineEase. On hard dining chairs, the cushion adds both shape and padding.

• May suit: people who sit for long stretches at a desk, in the car or on the couch and enjoy warmth behind the lower back
• May suit: anyone who wants a simple one-button cushion rather than a complicated massager
• May suit: buying for a parent or partner who finds heat packs fiddly
• Skip it if you want a deep, kneading massage — it uses gentle vibration
• Skip it if you're hoping to treat a diagnosed back condition — it's a comfort product, not a treatment
• Check with your GP first if you're pregnant, have a pacemaker, reduced heat sensitivity or recent surgery
