Stack and Sleep is an independent review site covering sleep optimisation technology and biohacking tools. Every product we feature has been researched thoroughly. We earn affiliate commissions from some of the links on this site — but our editorial judgements are entirely our own.
Why we started this
The sleep and biohacking space has a problem: most review sites are either written by people who haven't used the products, or they rank products based on who pays the highest commission. We wanted something different — a site where the recommendations are based on what actually works.
Replace this section with your personal story — why you got into sleep optimisation, what problem you were trying to solve, what products you've personally tested.
What we cover
We focus on four areas where the evidence is strong and the products are genuinely useful:
- Sleep trackers — Oura Ring, Whoop, Garmin Venu, RingConn and others
- Sleep supplements — magnesium, ashwagandha, glycine, L-theanine
- Recovery tools — red light therapy, cold plunge, infrared saunas
- Biohacking tools — CGM tracking, HRV monitoring, sleep environment optimisation
We do not cover mattresses or pillows. That market is dominated by large media companies with deep budgets. We focus on the areas where an independent voice can actually add value.
Our review process
We research products thoroughly before recommending them. Where we've personally used a product, we say so and provide real data. Where we haven't, we rely on published research, verified user data, and expert sources. We never fabricate experience.

Affiliate relationships
This site earns affiliate commissions from product links. We are members of the Amazon Associates programme, Impact.com, ShareASale, and several direct affiliate programmes. Full details at our Affiliate Disclosure page.
Earning commissions does not affect our editorial conclusions. If a product isn't worth buying, we say so — even if it pays a higher commission than the product we recommend instead.
No medical advice
Nothing on this site is medical advice. We review consumer products — we don't diagnose, treat, or advise on medical conditions. If you have a sleep disorder or health concern, speak to a qualified medical professional.
