Same checklist
Every brand in a category is scored the same way. We do not invent a new story for whoever pays more.
Who we are
SideBySide Test
A review site, not a shop. We buy the kits, run one checklist per category, and keep the ranking still — so you get an answer, not an ad order.
How we test
Real units
We test kits we can put on a bed, a couch, or a walk — photos of those units, not stock hype.
One #1
The ranking does not rotate for ads. The product we would buy for our own home stays #1 until the tests say otherwise.
What we cover
Open a category. Rankings and store links live inside those pages.
How we’re funded
If you buy through a marked affiliate link, we may earn a commission at no extra cost to you. Rankings are not for sale. See the affiliate disclosure.
Questions
What is SideBySide Test?
An independent review site. We test consumer products, publish how we scored them, and keep one ranking per category. We are not a manufacturer storefront.
Do you sell rankings?
No. A brand cannot pay to be #1. If you buy through a marked link we may earn a commission at no extra cost to you. That never changes a score. See the affiliate disclosure.
Who does the testing?
Stephanie Romiszewski leads the sleep-gear tests (continuity meters and sleep tracking for sheets; fill, heat, and wash for blankets). Pack tests are rain, walk, and load. Bylines sit on the review pages.
Where should I start?
Use the category links in the menu, or the cards on this page. Each category has the ranking and the guides. Store buttons live on the review pages, not in the navigation.
Is this medical advice?
No. Nothing on this site is a substitute for a clinician. If you have a health condition, talk to one before using conductive bedding or a weighted blanket.
