Sivio 100% Cotton Weighted Blanket (15 lb)
Best for: Synthetic-averse skin, natural-fiber preference
The natural-fiber pick — breathable 100% cotton shell over glass beads, for sleepers who reject synthetics on skin.
Almost every budget weighted blanket wraps its beads in polyester; Sivio uses genuine 100% cotton — the breathable, natural hand-feel that synthetic-sensitive skin wants. Fine beads in compact pockets, a wide weight range, and cheerful color options. Cotton runs warmer than cold-touch synthetics but breathes honestly, making it a year-round natural choice.

How our prices work
We show the price at our recommended retailer as at our last check of that offer (2026-10-31) and, when Amazon reports one, its list price for comparison. Amazon prices come from Amazon's own product data service and are refreshed twice a day; each one shows the date and time Amazon gave it, and one older than 24 hours is replaced by “Check price”. Other retailers' prices are checked by hand and show the date of that check. Retail prices move constantly, so the price on the retailer's own page at checkout is the one that applies.

Frequently asked questions
Why care about cotton?
Feel and breathability — polyester traps humidity against skin; cotton absorbs and releases it. Eczema-prone and texture-sensitive sleepers notice immediately.
Sivio vs Bearaby?
Same natural-fiber philosophy, different construction: Bearaby's knit is cooler; Sivio delivers cotton-on-skin with beads at budget price.
Does cotton sleep hot?
Warmer than cold-touch synthetics, cooler than minky/fleece. Mid-pack, honest.
Kids' options?
The 5-10 lb small sizes make it one of the better kid-weighted lines — apply the 10% rule strictly for children.
