## Less suited to

## Customer feedback

The available aggregate ratings are uniformly five-star, but the sample is small and no written customer feedback is supplied. That gives little detail about comfort, vibration, heat or battery performance, so buyers should treat those aspects as uncharacterized by customer comments here.

## Frequently asked questions

### Can the functions be used separately?
The listing says red and near-infrared light, warmth, vibration and the air cushion can be used separately or together. It also says warmth is activated with the red light, so that function may not be fully independent.

The listing claims up to 4.5 hours from its 5000mAh rechargeable battery, but does not specify the operating mode for that runtime. It also specifies a 30-minute automatic shutoff and says not to use the massager while charging.
### How much lift does the air cushion provide?
The listing says the built-in air cushion gradually raises the pillow's center by up to 4 inches.
