Cooling is relative to room temperature (3–8°C below ambient, strong level, pad under a fitted sheet). Heating range 28–38°C water temperature. Noise ~35 dB measured at 3 m.
Why Equinox
Air conditioning cools the room. Electric blankets cook the bed. Equinox does what neither can: it moves temperature-controlled water through a thin quilted pad under your sheet, so the surface you actually sleep on is exactly as cool — or as warm — as you want it. The same water-loop principle as $1,000+ smart-bed systems, without the app, the subscription, or the price.
Summer
The flip-the-pillow trick works for a minute. Equinox works all night: chilled water keeps circulating, so heat leaves your body instead of pooling in the mattress. Hot sleepers, night sweats, summer heatwaves — the pad simply carries the heat away.
Winter
Flip one mode and the same pad carries 28–38°C water warmth — the deep, even kind, not the prickly heat of electric wires. Pre-warm the bed before you get in, then let the timer wind it down as you sleep.
Safety by design
The only thing in your bed is a quilted pad of sealed water channels. Every heating element, every circuit, every moving part lives in the bedside unit a hose-length away. It's the reason hospitals and premium sleep systems all moved to water — and electric blankets didn't.

Setup
Pour one glass of tap water (200 mL) into the bedside unit and lay the quilted pad under your fitted sheet. Click the insulated hoses in.
Tap cool or warm, pick strong or gentle, set the 2–12 h timer. Two buttons — no app, no account, no firmware updates.
Water circulates silently under you all night and the unit switches itself off on schedule. Change modes when the season changes — that's it.
Hot sleepers, cold-footed partners, and everyone whose thermostat wars ended here.
i used to wake up soaked every summer night with the AC still running. put the pad on 2 weeks ago and i havent woken up hot once. the water thing sounds gimmicky until you feel your sheets actually stay cool at 3am
my wife runs cold, i run hot. we got the double pad and honestly the fix for us was me getting the cool side of the bed surface while the bedroom stays at a temp she likes. best money weve spent on the house this year
nothing touched my night sweats, not cooling sheets not the bamboo mattress topper. this actually pulls the heat away because its water not fabric marketing. i set it on gentle and sleep through the night again
was worried about a pump running in my bedroom all night. you genuinely cannot hear it over normal room noise, its quieter than my fridge. only wish the hoses were a touch longer for my bed frame setup
bought it for summer cooling and the heating mode ended up being the surprise. its a deep even warmth with no hot wires under me, like the bed was pre warmed by the sun. electric blanket went to goodwill
i almost paid 2 grand plus a subscription for the famous pod thing. this does the part i actually wanted, cool water under the sheet, for a fraction. two buttons, no app asking me to update firmware at bedtime
Equinox cools the pad 3–8°C (5–14°F) below your room temperature on the strong setting. In a 25°C bedroom that means a bed surface around 17–22°C — cool to the touch all night. It's relative to the room by design: enough to stop heat pooling around your body, without the shock of an ice bath.
The heating mode circulates water between 28°C and 38°C through the pad — from "takes the chill off" to "pre-warmed like someone was just lying there." Two levels, and the 2–12 h timer can wind it down after you fall asleep.
The bedside unit runs at roughly 35 dB — about the level of a quiet library, measured at a distance. It sits on the floor by your bed, and the pad itself is completely silent. Most sleepers report forgetting it's on.
Safer than the alternative. The pad is a sealed loop of welded water channels — there's no electricity anywhere in the bed. All heating, cooling and circuitry stay in the bedside unit on the floor, connected by insulated quick-release hoses. Water and electronics never share a compartment.
The Single pad (160 × 70 cm) covers one sleeper's side — ideal if your partner sleeps fine or you sleep alone. The Double pad (160 × 140 cm) covers the full top of a queen bed for couples who both want it. Both lie flat under any fitted sheet, on any mattress type.
About three minutes: lay the pad under your fitted sheet, click in the two hoses, pour in one glass (200 mL) of tap water and press a button. Top up occasionally; no plumbing, no tools, no app.
The unit draws up to 130W — about a laptop charger — and only works to hold the set temperature. Cooling your bed instead of the whole room typically costs a small fraction of running air conditioning overnight.
Orders are delivered in 5–10 business days with tracking. You get a 60-night trial: sleep on it for two months, and if it isn't for you we'll refund you in full. A 2-year warranty covers the unit.
Buy with confidence
A sleep system has exactly one test: how you feel in the morning. Run Equinox through a heatwave, a cold snap, or both. If it hasn't earned its place under your sheet after 60 nights, we'll refund you in full.
Cool in July. Warm in January. One quiet box and a glass of water.
