What a therapy bed actually does, how it differs from an adjustable bed or a massage chair, and what to notice during a home trial.

Published Thursday 3 September
Rather than a single up-and-down shake, cycloidal motors move in three directions at once, producing a rolling motion that spreads across the surface. It feels less like a phone buzzing and more like a gentle hum through the whole body.
Most therapy beds add low-level heat, adjustable and on a timer. People tend to use it in the evening.
HomeTrials does not make health claims and neither should the consultant. If you have a medical condition, talk to your doctor before using vibration or heat products. The demo is about comfort and whether you would use it, nothing more.
No. An adjustable bed lifts the head and feet. A therapy bed's main feature is the vibration and heat in the surface. Some products combine both.
Some are full beds, others are toppers that sit on your existing mattress. The consultant will tell you which they are bringing.
Cycloidal motors are quiet, usually quieter than a fan. You will hear it in a silent room but not over a television.
