Gravity Weighted Blanket
Gravity Weighted Blanket review — 15 lb and 20 lb deep-pressure fleece/microfiber blankets for anxious sleepers, plus hot-sleeper temperature notes.
The brand that made 15 lb blankets mainstream — deep pressure for anxious sleepers
Gravity popularized weighted blankets for adult sleep and anxiety. Typical advice is ~10% of body weight (15 lb is the common SKU). Evidence for insomnia is mixed; some people sleep better from deep pressure, others overheat. Not a cooling system — pair with temperature work if you are a hot sleeper.
Typical price: $150 – $250 USD
How It Works
Small trials on anxiety and sleep are mixed. Deep-pressure stimulation is the proposed pathway. It will not treat apnea or replace CBT-I. Kids and medically frail users need different rules — this listing is adult-oriented.
Deep Pressure
Even weight can downshift arousal for some nervous systems — similar logic to a firm hug, not magic GABA.
Size to Body
About 10% of body weight is the usual starting heuristic. Too heavy wrecks getting up and can feel panicky.
Heat Tradeoff
Glass-bead blankets trap heat. Duvet cover and a cool room help. Hot sleepers may prefer a lighter throw.
What You'll Experience
First Nights
Nights 1–4Love-it or claustrophobic. Give three nights unless you cannot move or overheat badly.
