Sleep Products & Gear

Most sleep products solve a specific problem, and many are sold as if they solve all of them. These guides look at mattresses, pillows, bedding, white-noise machines, trackers and supplements by asking what the product is actually meant to change, what the evidence says, and who is likely to notice a difference. A new pillow will not fix a circadian problem; a tracker can measure sleep without improving it. We favour fit and function over hype, and we flag claims that outrun the evidence.

• How to match a pillow and mattress to your sleep position, body size and pain patterns.
• Which bedroom purchases tend to matter most, and where expensive upgrades rarely pay off.
• What to know before buying sleep trackers or supplements, including accuracy and regulation.
