The BedJet, a device that attaches to the foot of your bed and blows temperature-controlled air under your covers, significantly improved sleep quality for one reviewer during hot, humid nights, despite its high price and a few design quirks.
According to the review, more than 30% of Americans struggle with sleep, and temperature is a common culprit. The BedJet aims to solve that by providing targeted heating or cooling directly between the sheets.
How the BedJet Works
The unit, about the size of a large shoebox, sits under the bed and connects to a flexible duct, similar to a clothes dryer hose, that vents at the bottom of the bed. An L-shaped clamp attaches the vent to the mattress, directing airflow over your body. The device sucks in room air, then either heats or cools it before blowing it under your comforter or sheets.
The review, conducted over several weeks in New England, found the BedJet effective at cooling on all but the most humid nights, eliminating the clammy feeling that often disrupts sleep. It does not lower the room temperature like an air conditioner, but the airflow provides a cooling sensation.
Features and Control
The BedJet comes with a remote control that is described as "overly large and complex," offering adjustments for temperature, fan speed, and a timer. There are three modes: cool, heat, and turbo (an accelerated heating setting for initial use). By default, it runs for 10 hours, but you can adjust it for naps or longer sleep periods.
An app provides more precise control, including a "biorhythm" feature that allows you to schedule temperature changes throughout the night, such as cooling in the middle of the night and warming in the morning. However, the reviewer found this feature didn't fit his unpredictable sleep patterns.
For couples, a Dual Zone model is available, allowing individual temperature control on each side of the bed. The reviewer tested this model, but his wife, who has neuropathy in her feet, found it uncomfortable because she couldn't feel the temperature changes.
Quirks and Considerations
The feeling of a draft under the sheets takes getting used to, and the airflow can be uneven, often leaving the legs colder than the rest of the body. An optional accessory, the Cloud Sheet, is a two-layer sheet with a permeable bottom layer that helps distribute air more evenly, but it costs an additional $139.
On nights with very high humidity, the BedJet was less effective, and the reviewer found himself throwing off the sheet in his sleep. Pet owners should also note that animals may be attracted to the puffed-up sheets; the reviewer's dog Jasper mistook it for a new bed and blocked the airflow, causing the reviewer to wake up sweaty.
The Cloud Sheet is only available in white, which is impractical for pet owners, as it quickly collects fur and footprints. However, it is machine-washable and can be used alone on warm nights.
Value and Verdict
The BedJet starts at $478 for the half-bed model, making it an expensive investment. The reviewer notes that a $45 fan and a $40 electric throw blanket could achieve similar results, but the BedJet offers more precise control and is more comfortable on cooler nights.
Despite the drawbacks, the reviewer concludes that the BedJet provides a luxurious way to fall and stay asleep, with a cool breeze on hot nights and a warm puff on cold ones. He looks forward to using it in winter for the heating function.
