You’ve finally done it. You bought that massive, four-foot-long body pillow because your back was killing you or you just wanted something to hug at night. It’s a game-changer. But then comes the laundry day struggle. Most people realize pretty quickly that a standard pillowcase for long pillow sets isn’t just a "larger version" of a normal case. If it’s too tight, your plush pillow turns into a concrete log. Too loose? You’re tangled in a mess of microfiber by 3:00 AM.
It’s annoying.
Honestly, the search for the perfect cover is where most people give up and just wrap a spare twin sheet around it. Don't do that. Whether you are using a 54-inch body pillow for pregnancy support or a 72-inch dakimakura, the physics of a long pillow demand a specific type of textile approach.
The Geometry of the "Long Pillow" Problem
Size is the obvious starting point, but it's rarely the finish line. Most "long pillows" sold in big-box stores like Target or Walmart are roughly 20 by 54 inches. This is the industry standard for a body pillow. However, if you’ve ventured into the world of orthopedic bolsters or specialized side-sleeper tools, you might be looking at dimensions like 20 by 60 or even 20 by 72.
If you buy a pillowcase for long pillow that matches the dimensions exactly, you're going to struggle. Why? Because pillows have loft. A 20-inch wide flat piece of fabric won't easily accommodate a pillow that is 8 inches thick. You need those extra couple of inches in the circumference to allow the fill—whether it’s memory foam or polyester fiberfill—to expand. If you compress the fill with a tight case, you lose the ergonomic benefits you bought the pillow for in the first place. It becomes too firm. It stops contouring to your neck or knees.
Cotton vs. Silk: The Friction Factor
Let’s talk about skin. When you’re using a long pillow, you aren't just resting your head on it. Usually, your arms and legs are wrapped around the thing. This means a massive increase in surface area contact with your skin.

If you choose a cheap, high-polyester blend, you’re going to sweat. Synthetic fabrics don't breathe well. This leads to that "sticky" feeling in the middle of the night. Cotton is the old reliable here. A long-staple cotton, like Egyptian or Pima, offers breathability. But there is a catch: cotton creates friction. If you’re a restless sleeper, cotton can tug at your skin or hair.
This is why silk and satin have exploded in popularity for the pillowcase for long pillow market. Real mulberry silk is protein-based. It’s naturally temperature-regulating. It’s also incredibly expensive for a five-foot piece of fabric. Many people opt for high-quality polyester satin as a budget-friendly alternative, which mimics the "slip" of silk but lacks the cooling properties.
Closures: The Great Zipper Debate
Most standard pillowcases are "envelope" style. You slide the pillow in, and there’s a little flap of fabric to hide the end. For a long pillow, this is often a disaster. Because these pillows are heavy and move around a lot, they tend to "squirt" out of envelope closures like a tube of toothpaste.
I always recommend a hidden zipper.
A zipper keeps the pillow contained. It maintains the shape. But—and this is a big "but"—the zipper needs to be high quality. Look for YKK zippers or "invisible" nylon coils. If you get a cheap metal zipper on a 54-inch case, it’s going to snag in the wash or, worse, scratch your leg while you sleep. Some brands, like those found on specialized bedding sites or Etsy, will put the zipper on the long side. This makes it ten times easier to get the pillow inside. Shoving a five-foot foam insert through a 20-inch hole at the end is basically a workout. Nobody wants that on a Sunday afternoon.

Why Materials Like Bamboo and Tencel are Winning
In the last few years, we’ve seen a massive shift toward "regenerated cellulose" fibers. You probably know them as Bamboo or Tencel (lyocell).
Basically, these are made by taking wood pulp (from bamboo or eucalyptus), dissolving it in a solvent, and spinning it into fiber. The result is a fabric that feels cooler than cotton and is more absorbent. For a pillowcase for long pillow, this is actually a massive win. Because long pillows trap body heat between your torso and the pillow, having a fabric that actively wicks moisture away is the difference between a good night's sleep and waking up in a swamp.
Tencel is particularly interesting because it’s much more durable than bamboo viscose. It holds its shape. If you’re washing a massive pillowcase every week, you don’t want it to stretch out and become a baggy sack. Tencel stays crisp.
The "Washing" Reality
Let's be real for a second. You probably don't wash your body pillow cover as often as your standard pillowcases. It’s big, it’s a pain to take off, and putting it back on feels like wrestling an alligator.
Because of this, the fabric choice for your pillowcase for long pillow needs to be antimicrobial or at least highly washable. This is where linen comes in. Linen is tough. It actually gets softer the more you wash it. It has natural filtered properties that make it resistant to bacteria. It has that "lived-in" wrinkled look, which is great because a five-foot stretch of fabric is going to wrinkle the second you hug it anyway. If you hate ironing, stay away from 100% cotton percale for long pillows. It will look like a prune within ten minutes of use.

Custom Sizes and the "Dakimakura" Subculture
It would be a mistake to talk about long pillowcases without mentioning the "Dakimakura" or Japanese hugging pillow. These are typically 150cm or 160cm long (about 59 to 63 inches).
The community surrounding these has actually pushed fabric technology forward quite a bit. They use a material called "Two-Way Tricot." It’s a blend of polyester and polyurethane that can stretch in all directions. It’s incredibly soft—almost like "peach skin"—and very cold to the touch. Even if you aren't into the specific hobbyist designs usually associated with these, the fabric itself is top-tier for anyone who wants a stretchy, form-fitting pillowcase for long pillow. It’s the closest thing to a "second skin" for a pillow.
Practical Steps for Choosing Your Next Cover
Don't just click "buy" on the first thing that pops up. Stop and think about how you actually sleep.
- Measure the actual loft. Take a tape measure and go around the thickest part of the pillow. If that circumference is 40 inches, your case needs to be at least 21 inches wide when laid flat.
- Check the weight. If you have a heavy shredded memory foam pillow, a thin 15-momme silk case might tear. You need something with a bit more "heft," like a 400-thread-count cotton or a heavy linen.
- Look for the zipper orientation. A side-loading zipper will save your sanity. If it’s an end-loader, make sure the opening is reinforced with double stitching.
- Prioritize temperature. If you sleep hot, go with Tencel or Linen. If you’re always cold, a high-quality flannel or jersey knit (like a t-shirt) feels amazing and cozy on a long pillow.
Finding the right pillowcase for long pillow is ultimately about balancing the tactile feel against the maintenance. If you’re going to spend 8 hours a day wrapped around this thing, the fabric matters more than the color. Invest in a material that handles moisture well and a closure system that doesn't let the pillow escape halfway through the night. Your back—and your skin—will thank you.
To keep your long pillow in peak condition, always wash the cover inside out to protect the fabric surface and zip the zipper shut before throwing it in the machine to prevent it from snagging on other clothes. This small step can easily double the lifespan of a high-end Tencel or silk cover.
