Prime Day Deal: Mellanni’s Cooling, Temperature-Regulating Sheets Are 40% Off
If you sleep hot — or share a bed with someone who does — the sheets matter more than you’d think. Mellanni’s bestselling brushed-microfiber set is breathable and moisture-wicking, so it helps move heat and sweat away instead of trapping it, and it stays comfortable across seasons. For Prime Day, the set is 40% off.
The deal
For Prime Day — June 23–26, 2026 — Mellanni’s brushed-microfiber sheet set is 40% off. It’s a Prime Day deal, so a Prime membership is required, and the price ends when the event closes on June 26 (or earlier if your size and color sell out). The set comes in a wide range of sizes and colors, and the discount applies across the lineup.
What it is
It’s Mellanni’s classic four-piece set — a flat sheet, a fitted sheet, and two pillowcases (one pillowcase on twin sizes) — in the brand’s signature brushed microfiber with a triple-stitch embroidered hem. The fabric is woven to be breathable and moisture-wicking for airflow, which is what helps it regulate temperature and sleep cooler than a heavier set. The fitted sheet fits mattresses up to 16 inches deep, and the whole set is wrinkle-, fade-, and stain-resistant, so it looks made-up straight out of the dryer.
How to use it
Match the size to your bed (twin through king) and check that your mattress is 16 inches deep or less, since that’s what the fitted sheet is sized for. Wash before the first use and tumble dry; the wrinkle-resistant microfiber means you can make the bed right out of the dryer. Because it’s breathable and lightweight, it works as a year-round set — and it’s an easy upgrade for anyone who runs warm at night.
Who it’s for
It’s for hot sleepers, anyone in a warm climate, and households that want one set they can use through every season. The moisture-wicking weave is the draw if you tend to overheat or wake up clammy, and the low-maintenance, wrinkle-resistant finish makes it a practical pick for primary bedrooms, guest rooms, and kids’ rooms. If your mattress is thicker than 16 inches, look at Mellanni’s extra-deep-pocket version instead; if you want all-cotton or percale, this is a different, smoother feel.
