How To Choose A Mulberry Silk Pillowcase That Lasts
The problem with your current pillowcase
Most people never think about their pillowcase until something nudges them. Maybe it is the sleep crease pressed into your cheek that takes until mid-morning to fade. Maybe it is hair that looked fine at bedtime and looks like a bird's nest by 6am. Or maybe it is simply that cotton gets warm, and on a humid night you end up flipping the pillow over and over looking for a cool patch that is not there.
Cotton is a good fabric. It is cheap, tough and washes in a machine. But the fibres are short and the woven surface has texture, so it grips. Anything resting on it (your face, your hair) gets held in place and dragged around as you move. Over seven or eight hours, that adds up.
Silk works the other way. The filament is long and continuous, and the finished fabric has a slick surface. Hair and skin slide over it with much less friction than a cotton weave. That is the core reason people switch, and it is a material fact about the fibre rather than a promise about what will happen to you.
What momme actually tells you
If you shop for silk bedding for more than ten minutes you will run into the word momme. It is pronounced "mummy" and it is the traditional Japanese measure for silk fabric weight. The higher the number, the heavier and denser the cloth.
Here is the practical version. Below about 16 momme, silk starts to feel thin. It drapes beautifully but it wears out faster, and seams can pull. Above about 22 momme you are into heavy silk, which costs considerably more and can feel almost stiff on a pillow. The 19 momme range is where most quality silk bedding sits, and this pillowcase is a 19 momme fabric. It has enough body to handle regular washing without going flimsy, while still draping softly over the pillow.
So when someone advertises the best 19 momme silk pillowcase, they are really saying they have landed on the standard that experienced silk buyers look for. It is not a gimmick number. It is the balance point.
Grade 6A and why thread count is the secondary number
The other spec on this listing is Grade 6A. That refers to the raw silk filament itself: how long the threads are, how evenly they were reeled, and how few breaks they contain. Grade 6A is the top of the common grading scale used in silk bedding. Long, even threads produce a smoother fabric with a consistent sheen and no slubby patches.
Thread count gets quoted too, at 600 here. With cotton, thread count is the headline figure. With silk it is secondary, because the fibre quality and momme weight matter more to how the finished cloth behaves. A 600 thread count weave in 19 momme Grade 6A silk tells you the weave is fine and tight. It is useful supporting information rather than the main event.
One thing worth checking on any silk pillowcase is whether both sides are silk. Some products use silk on the sleeping face and a cheaper fabric on the reverse to cut cost. This one is double-sided mulberry silk, so there is no wrong way up and no hidden compromise.
Getting the size right
This is the part that trips people up, and it is easy to get right with a tape measure.
The pillowcase measures 75cm long by 50cm wide, which is a standard queen fit. Before you order, lay your pillow flat and measure it corner to corner in both directions. If your pillow is meaningfully larger, the seams will strain and the silk will pull at the stitching. If it is much smaller, the case will bunch and slide around all night, which defeats the purpose of a smooth surface.
Pillow sizing is not perfectly standardised between brands, which is why the measurement matters more than the label on your old pillow. Two minutes with a tape measure saves a return.
The zipper question
Silk pillowcases come with two common closures. Envelope style tucks the excess fabric back over itself. Zip style uses a zipper, usually hidden in the seam.
This one has a hidden zipper. In practice that means the pillow stays where you put it, which matters more with silk than with cotton because silk is slippery. An envelope closure on a slick fabric can let the pillow work its way loose overnight. The zip also gives a neater line when the bed is made, since nothing gapes open.
If you are sensitive to hardware near your face, lay the pillow with the zip end pointing away from where you sleep. The zipper runs along the short end and sits within the seam, so most people never notice it.
Caring for silk without the drama
Silk has a reputation for being fussy. It is not really fussy, it just has different rules, and once you know them the routine takes five minutes.
The care instruction for this pillowcase is hand wash only. Fill a basin with cool water and a small amount of mild detergent made for delicates. Submerge the pillowcase, swirl it around gently for a few minutes, then rinse in clean cool water until no suds remain. Do not scrub, do not wring and do not leave it soaking for an hour.
To dry, lay the pillowcase flat on a clean towel, roll the towel up and press to draw out the water. Then hang it in the shade or dry it flat. Direct sun and heaters are the enemies here, both for the fibre and for the white colour. If it needs a press, use the lowest silk setting on the iron, work on the reverse side, and do it while the fabric is still a touch damp.
Three things to avoid entirely: bleach, hot water and fabric softener. Bleach breaks down the protein fibre, hot water dulls the finish, and softener leaves a coating that kills the slick surface you paid for.
Wash it every week or two, in line with the rest of your bedding. More often if you use heavy hair oils or thick night creams, since those transfer onto the fabric.
Who this suits
If you sleep hot, silk is worth trying. The listing describes the fabric as breathable with temperature-control properties and cool to the touch, which is consistent with how silk behaves as a fibre. People hunting for the best breathable pillowcase in a warm climate often land on silk for exactly this reason.
If you have long hair that tangles overnight, the lower friction surface is the main draw. Same if you wake up with pillow creases on your face.
If you want a gift that is useful rather than ornamental, a plain white silk pillowcase is a safe pick. You do not need to know the recipient's colour scheme, and white silk reads as considered rather than loud. It arrives gift-ready, which saves you a step.
If you would rather throw everything in a hot machine wash and forget about it, silk is probably not for you. Buy good cotton instead. There is no shame in matching the fabric to the routine you will actually keep.
Buying two
This listing is a single pillowcase, one per pack. On a queen bed with two sleepers, most people order a pair so the bed looks even and both people get the same surface. Worth factoring into your order rather than discovering it after delivery.
Delivery and returns
Orders ship from Australian warehouses and typically arrive in 3 to 7 working days. Remote postcodes can take a little longer.
Returns are accepted within 14 days of delivery, provided the pillowcase is unused and unwashed in its original packaging. Once bedding has been slept on or washed it cannot be returned, which is standard across the industry for hygiene reasons. So check the size against your pillow before you take the tags off.
The short version
This is a single queen pillowcase in 19 momme Grade 6A mulberry silk, white, with silk on both sides, a 600 thread count weave, a hidden zipper and a 75cm by 50cm fit. It weighs 0.1 kg and it is hand wash only.
Measure your pillow first. Order two if you share the bed. Wash it in cool water with a gentle detergent, keep it out of the sun, and skip the bleach. Do that and it will hold its finish for a long time.
