About this site · checked Oct 17, 2026
How this site checks prices and specs
Every price on this site comes from the maker's own store with the date it was checked, every spec from the maker's product page, manual or help center, and every electricity rate from the EIA. Nothing is tested at home.
Where numbers come from
Prices, specs and rates
Each number on a page can be traced to a dated source.
A price is recorded with the store page it came from, the variant (bed size and zones) and the date. A struck-out price is the store’s own list price. Stores that show prices in the visitor’s currency are checked against the product page: anything not in US dollars is left out.
Specs are quoted from the maker’s own pages. When a maker publishes two different figures for the same thing, both are shown with their sources.
| Data | Source | Checked |

The 5-year cost
How the total is calculated
Electricity is the largest uncertain line, so it is shown as a ceiling.
Makers publish only maximum power, so electricity is an upper bound: by default the unit runs at full power for 8 hours, 365 nights a year. You can lower the share of the night in the calculator. Systems whose makers publish no power figure show their total with a “+”: electricity is not in it.
Not counted: sales tax, shipping, promo codes, HSA or FSA savings and any change in the air-conditioning bill.
- 1
kWh a year
watts × units × hours × nights × share of the night at full power ÷ 1,000
- 2
Electricity a year
kWh × the state rate in cents ÷ 100
- 3
Total
price + subscription years + years × electricity + cleaner from year 2
- 4
Per night
total ÷ (years × nights a year)
Order of results
How results are ordered
Results are sorted by how well a system matches your choices and then by the total cost. Brands that pay nothing (Eight Sleep, Orion, Perfectly Snug, bFan) are listed the same way; their buttons lead to our review rather than the store.
Money from partners never changes a total or a fit rule.
Fit first
Bed size, zones, water, subscription and budget decide what is shown.
Full totals before partial
Systems with published power come before those without.
Partners only on a tie
A brand with a partner program ranks higher only when everything else is equal.
How texts are written
Texts and checks
The texts are written by AI from the saved facts of each page. Code then checks every draft: each number must appear in those facts, claims must name the maker or publisher, and drafts with health promises, superlatives or sales language are rejected. A page that fails is not published.
If a fact is missing, the text says the maker does not publish it.
Partner programs on this site
BedJet and Sleepme run partner programs; other system makers do not. Buttons open the store in a new tab.
