Prime Day Deal: Mellanni’s Extra-Deep-Pocket Sheet Set Is 38% Off
If you’ve ever fought a fitted sheet that pops off the corner of a thick mattress at 2 a.m., the appeal of Mellanni’s sheet set is immediate: the fitted sheet has an extra-deep pocket built to fit mattresses 18 to 21 inches deep, including the ones with a pillow-top or a foam topper stacked on top. And for Prime Day, the set is at one of its best prices of the year.
The deal
For Prime Day — June 23–26, 2026 — Mellanni’s extra-deep-pocket sheet set is 38% off. This is 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 range of sizes and colors, and the discount applies across the lineup.
What it is
It’s a brushed-microfiber sheet set — a flat sheet, a deep-pocket fitted sheet, and pillowcases — finished to feel soft and hotel-smooth rather than crisp. The headline feature is that fitted-sheet pocket: at 18 to 21 inches, it’s deeper than a standard sheet, so it actually stays put on a tall mattress, a mattress-plus-topper combo, an air mattress, or an adjustable bed. The microfiber is also wrinkle-, fade-, and stain-resistant, so it comes out of the dryer ready to go on the bed without ironing.
How to use it
Measure your mattress depth before ordering — the deep pocket is the whole point, but it’s sized for the 18-to-21-inch range, so a very thin mattress may leave a little extra fabric to tuck. Match the size to your bed (twin through king), wash before first use, and tumble dry; because the microfiber is wrinkle-resistant, you can make the bed straight out of the dryer. Keep a second set on hand if you want to swap on laundry day.
Who it’s for
It’s for anyone with a deep mattress — a thick hybrid, a pillow-top, or a mattress with a foam topper added — who’s tired of fitted sheets that won’t stay on. It’s also a low-effort pick for guest rooms, air mattresses, and adjustable beds, and the wrinkle-resistant microfiber makes it an easy-care choice if ironing sheets isn’t your idea of a weekend. If you specifically want all-cotton or percale, this isn’t that — it’s a soft brushed microfiber.
