Prime Day Deal: Mellanni’s “Unbelievably Soft” Microfiber Sheets Are 40% Off

The thing people keep saying about Mellanni’s sheets is some version of “I can’t believe how soft these are for the price.” The brushed microfiber has a smooth, almost cool-to-the-touch feel that’s closer to a hotel bed than to what you’d expect from a budget set — and for Prime Day, it’s 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 a complete brushed-microfiber sheet set — a flat sheet, a deep-pocket fitted sheet, and pillowcases. The selling point is the feel: the microfiber is brushed to a soft, smooth finish that stays comfortable year-round, and it’s wrinkle-, fade-, and stain-resistant, so it comes out of the dryer looking made-up rather than crumpled. The fitted sheet also has an extra-deep pocket (18 to 21 inches) that fits thick mattresses, pillow-tops, toppers, and adjustable beds without popping off the corners.

How to use it

Pick your bed size (twin through king) and check your mattress depth — the deep pocket is built for the 18-to-21-inch range. Wash before the first use and tumble dry; because the microfiber resists wrinkles, you can put the sheets on the bed straight out of the dryer with no ironing. They’re light enough to use all year, and a second set in a different color makes laundry-day swaps painless.

Who it’s for

It’s for anyone who wants a soft, low-maintenance set that doesn’t cost a fortune — a smart pick for primary bedrooms, kids’ rooms, guest beds, and dorms alike. The deep pocket makes it especially useful on thick or topped mattresses, and the easy-care microfiber suits households that aren’t about to iron their sheets. If you specifically want all-cotton or crisp percale, this is a different feel — it’s a soft, smooth brushed microfiber.
