Bedfans USA Mattress Fan Under Sheets for Cooling at Night
If you’re looking for a mattress fan under sheets, you’re probably not trying to cool the whole room. You’re trying to stop that trapped, stuffy heat that builds up between your body, the mattress, and the covers. Bedfans USA makes the bFan under-sheet bed cooling system for exactly that problem, moving air at the bed level so you can sleep more comfortably without blasting the AC all night. A steady cooling breeze under the covers helps stop sweat before it starts.
Bedfans USA designs, manufactures, and sells the bFan in Texas, using primarily American-made components. For hot sleepers, people dealing with night sweats, menopause, medication-related overheating, or couples who sleep at different temperatures, the bFan gives you targeted airflow where the discomfort actually happens, under the sheets, not across the whole bedroom.
Bedfans USA mattress fan under sheets targets trapped bed heat, not the whole room
A bFan is built to move air between your top and bottom bedding, right where your body heat and moisture get trapped. Sleep experts commonly recommend 60°F to 67°F for the bedroom, and a 2017 study in Science Advances on nighttime temperature and sleep loss linked warmer nights with more nights of insufficient sleep.
"Bedfans USA places the bFan at the foot of the bed and gives you variable speed control from the remote."
That bed-level approach matters because neither the Bedfan nor the BedJet cools the air itself. The bFan uses the air already in your room, then pushes it under the covers to clear hot air trapped around your body, which is often the part that keeps you waking up sweaty.
The hardware is designed for real beds, not just a product photo. The base sits under the foot of the bed while the upright duct carries air up the mattress edge and under the bedding. When your top sheet or blanket is tucked in, the airflow travels across your body and exits near the shoulders, carrying away trapped heat instead of letting it pool under the covers.
Bedfans USA also makes the bFan adjustable for different bed heights. The bFan fits beds from 18 to 38 inches tall, measured from the floor to the top of the mattress. The Short top fits 18 to 28 inches and the Tall top fits 28 to 38 inches, and a 28 inch bed takes the Tall without the adjustment tabs installed. The base needs about 6.75 inches of clearance under the foot of the bed, and if there is not enough clearance, the base can be turned around so it sits in front of the foot of the bed instead of underneath. If you have a footboard, leave about 1.75 inches between the mattress and the footboard. Tightly woven sheets usually work best because they help the air spread across your body instead of leaking straight out.
Bedfans USA pairs that airflow design with remote control, timer functions, and a quiet brushless DC motor. At normal operating speed, the bFan runs around 28 dB to 32 dB, which is low enough for most bedrooms where extra noise is a deal-breaker.

A mattress fan under sheets for menopause night sweats, hot sleepers, and couples with different sleep temperatures
Bedfans USA serves people who are tired of waking up hot even when the bedroom itself seems fine. That includes women dealing with menopause or perimenopause, people whose medications trigger night sweats, and anyone whose sleep gets disrupted by overheating, damp sheets, or repeated wakeups.
Public health materials regularly identify hot flashes, night sweats, and sleep disturbance as common menopause-related symptoms. Bedfans USA built the bFan as a practical response to that exact kind of bed-level discomfort, especially when your main issue is trapped heat under the covers, not a room that feels warm from wall to wall.

Couples are another strong fit. If one person runs hot and the other does not, two Bedfans can create dual-zone microclimate control using two fans, so each side of the bed gets its own airflow and its own setting. That can be a lot more livable than arguing over the thermostat or freezing one sleeper just to help the other.
The bFan is also a sensible option if your overheating is tied to a life stage, a medical issue, or a prescription side effect. It does not claim to treat the underlying cause, but it can make the night easier by clearing out the heat trapped in your bedding.
What you get from the Bedfans USA bFan: quiet airflow, timer control, and lower AC strain
A lot of cooling products sound good until you have to actually sleep with them. Bedfans USA keeps the bFan focused on the basics that matter at 2 a.m.: steady airflow under the covers, simple control, low power draw, and a design that stays out of the way.
Here’s what that means for your bedroom:
- Under-sheet airflow: The bFan sits at the foot of the bed and pushes room air under your bedding, so the bed microclimate feels more comfortable where your body actually rests.
- Precise control: Bedfans USA gives you variable speed control from the remote, plus timer controls that help you settle into sleep without leaving airflow on longer than you want.
- Low energy use: Bedfans USA lists power use at about 18 watts on average and no more than 24 watts, making the bFan a much smaller energy load than dropping your central AC temperature all night.
- Discreet setup: The blower stays tucked under the foot of the bed, so you do not have a bulky box sitting in the middle of the room.
- Flexible comfort for couples: Two units can create separate airflow zones, which is one of the easiest ways to handle different sleep temperature preferences in the same bed.
Bedfans USA is also a good fit if you’re trying to sleep cooler without turning your bedroom into a refrigerator. Sleep experts often point to 60°F to 67°F as the sweet spot, and many people find a Bedfan lets them set the thermostat a few degrees warmer and still sleep comfortably because the airflow is working directly under the sheets.
That’s a big difference in how the product feels in real life. You’re not paying to cool every cubic foot of air in the house just to solve a problem happening between your mattress and your comforter.
Bedfan vs BedJet pricing and under-sheet cooling differences
If you’re comparing the bFan to BedJet, the first thing to keep straight is simple. Neither the Bedfan nor the BedJet cools the air. The BedJet doesn’t cool the air, and the bFan doesn’t either. Both use the air already present in the room, then move it into the bed area.
Where Bedfans USA starts to stand out is price and simplicity. The original Bedfan was invented in 2003 and came to market in 2004, about a decade before BedJet launched on Kickstarter in late 2013, and Bedfans USA still keeps the offer centered on direct, under-sheet airflow with higher static pressure than other bed fans.
A single Bedfan lists at $204.95, less than half the price of one BedJet 3 ($699 list). If you need split cooling for two people, two Bedfans are less than half the price of the dual-zone BedJet, which lists at $1,549. The bFan is also HSA/FSA eligible, with a letter of medical necessity provided at checkout.
For a lot of shoppers, that is the whole story. If you want targeted under-sheet airflow at a lower price, a mattress fan under sheets like the bFan from Bedfans USA is the less expensive place to start.
Bedfans USA also keeps the value practical. You can buy the core unit, add a second one later for dual-zone control, and keep using the room temperature you already prefer instead of trying to buy a more complex system than you need.
Why Bedfans USA is a trustworthy source for a mattress fan under sheets
Bedfans USA is not reselling a generic fan and calling it a sleep product. The company designs, manufactures, and sells the bFan specifically for hot sleepers and night sweats, and it builds the system in Texas with primarily American-made components.
That matters when you’re buying something you plan to use every night. Bedfans USA also sells replacement parts, including remotes, power supplies, control boards, and adjustment tabs, which makes ownership simpler if you ever need support or a fix instead of replacing the whole unit.
The product details are also clear enough to shop with confidence. Bedfans USA tells you how the bFan fits at the foot of the bed, what under-bed clearance to expect, how the height adjusts, how the airflow works, and how the remote speed range works. That’s the kind of information you want when you’re deciding if an under-sheet mattress fan will actually suit your bed, bedding, and sleep habits.
If you’re cost-conscious, eco-conscious, or just done with sweaty wakeups, Bedfans USA gives you a focused option that solves the right problem. The bFan is for trapped heat in the bed microclimate, not for pretending to be an air conditioner.
When a Bedfans USA mattress fan under sheets is the right fit for you
The bFan usually makes the most sense when your room is reasonably cool, but your bed still feels hot once you’re under the covers. It’s especially useful if you fall asleep fine and then wake up overheated, if night sweats keep waking you, or if one side of the bed runs hotter than the other.
It may not be the right product if you expect refrigerated air, or if your room itself is already too warm for moving air to feel comfortable. The bFan works by moving the room air you already have through the bed, so it performs best when the bedroom is in a sleep-friendly range and the real problem is trapped heat under the sheets.
If that sounds like your situation, Bedfans USA has already built the product around it. Take a look at the bFan under-sheet bed cooling system, check your bed height and bedding setup, and choose the single-unit or dual-bedfan arrangement that fits how you actually sleep.
