Cool the bedroom before you shop for a cooling bed
Cool the room before you buy a cooling mattress. A cover can't beat a shut window and a winter duvet in June.

The cheapest climate control in a bedroom is still the window, the radiator, and the duvet you refuse to change in May. A mattress cover is downstream of all three. We sell Current for people who have already done the room and still overheat. We don't sell it as a substitute for a shut, sunny room.
What "cool" usually means in public guidance
Sleep guidance aimed at the public tends to land on a cool bedroom, not a cold one. You'll see a range repeated in the high teens Celsius, roughly the mid-60s Fahrenheit. That isn't a Thaw measurement and it isn't a target you must hit with a thermometer to deserve a good night. It's a hint: if the room feels like the kitchen did after cooking, the bed is not the first lever.
Bodies differ. A person who runs cold will hate the room their partner calls perfect. Two duvets is a legitimate design. Allnight is one duvet, not a marriage counselor. You can each have a covering. People do.
The order of operations
Open the window if the air outside is cooler than the air inside. If it isn't, because the week is a heat wave, a fan moving air across the bed does more than a new foam. Darken the room in the afternoon so the sun isn't still in the wall at 10. Swap the winter duvet for something lighter. Then, and only then, decide the mattress is the remaining problem.
If you skip to the mattress, Current will feel like a broken promise. It is a hybrid, 27 cm, medium, with a cover and a build that give heat a path. It is not an air conditioner. The hot sleeper essay is the product-level version. This page is the room.
Foam, coils, and why the build still matters after the window
A thick foam hug holds warmth against your skin. That's Drift's risk on a warm night, and it's also why Drift feels kind in a cold bedroom. Coils leave more air in the bed. Air is not cold air. It's a path. If the room is 26°C, the path leads to more 26°C air. Fix the 26 first.
A protector and a sheet can undo a cooling cover if they're thick, waterproof in a way that doesn't pass vapor, or piled three deep. Keeper is there to stop spills. If you need it, use it, and don't add two more layers "just in case." The sheet should be the cloth you can wash, not a quilt.
Partners who disagree
One of you is kicking off the covers and the other is hunting for them. Split the covers before you split the mattress. A too-warm room plus a too-warm duvet plus a foam bed is three causes. Remove them one at a time or you will blame Current for a duvet.
A small experiment before checkout
For three nights, change only the room and the duvet. Same mattress, same sheet, lighter cover, window or fan doing something real. Write hot, fine, or cold in the morning. If all three nights are fine, you don't need Current. Spend the money on the feel you actually want. If all three are still hot, and the room truly dropped, Current is a fair next spend. If the nights disagree, you don't have a mattress problem yet. You have a draft, a duvet that was half on, or a partner who closed the window.
Write the three words on paper, not in a notes app you'll decorate. Hot, fine, or cold is the whole scale. If you need a paragraph, the experiment is already muddy.
Do the experiment in the season you're complaining about. A January test doesn't buy a July bed. And if you travel for work and only overheat in hotels, fix the hotel duvet first. People order a cooling mattress from a bad hotel week and then sleep cold at home for a year. The trial would catch it. The three-night note catches it before the box.
FAQ
What temperature should I set the thermostat?
We don't have a required number. Use the public range as a starting hint, then believe the person who sleeps there. If you need the room warmer for a health reason, follow that and don't let a blog override it.
Will a cooling pillow do more than a cooling mattress?
It can, if the head is where you overheat and the room is already reasonable. We don't sell a cooling pillow as a separate claim. Rest and Keel are fill and shape. Don't expect them to refrigerate you.
Is Current worth it in winter?
If your winter bedroom is actually cool, you may not need it. Harbor or Drift might be the kinder feel. If your winter bedroom is a heated box, Current still has a job. Judge the room you have, not the season on the calendar.
