Silk Pillowcase Buying Guide: How to Choose the Right Silk Pillowcase
A silk pillowcase can look simple, but there is more to choosing one than picking a color you like.
Momme weight, silk type, fabric construction, closure design, sizing, and even whether both sides are made from silk can all affect how a pillowcase feels and performs over time.
If you are comparing silk pillowcases and are unsure what terms such as 22 momme, mulberry silk, or Grade 6A silk actually mean, this guide breaks down the most important things to look for.
Silk Pillowcase Buying Guide: What Really Matters?
When shopping for a silk pillowcase, consider:
- Silk type
- Momme weight
- Silk quality
- Double-sided vs. single-sided construction
- Closure style
- Pillowcase size
- Color and finish
- Care requirements
- Brand transparency
Let’s look at each one in more detail.
1. Start With the Material: Look for Real Silk
The first question is simple:
Is the pillowcase actually made from silk?
Silk and satin are often confused, but they are not the same thing.
Silk is a natural protein fiber, while satin describes a weave structure. Satin pillowcases can be made from silk, but many are made from polyester or other synthetic fibers.
That does not necessarily make satin a bad material, but it is different from natural silk.
If you specifically want a silk pillowcase, look for clear product information such as:
- 100% silk
- 100% mulberry silk
- Momme weight
- Silk grade or quality information
- Fiber composition
Be cautious when a product is described simply as “silky,” “silk-like,” or “satin” without clearly stating the fiber content.

2. What Is Mulberry Silk?
Mulberry silk is one of the most commonly used types of silk in premium bedding.
It is produced by silkworms that are traditionally fed mulberry leaves. The resulting silk fibers are known for their smoothness, fineness, and consistency.
When shopping for a pillowcase, you will often see phrases such as:
100% Mulberry Silk
This tells you the type of silk being used, but it does not tell you everything about the fabric.
You should still look at:
- Momme weight
- Construction
- Weaving quality
- Finishing
- Stitching
Think of “mulberry silk” as one part of the overall quality equation rather than the only thing that matters.

3. Understand Momme Weight
Momme, often written as mm, is a traditional measurement used to describe the weight and density of silk fabric.
For silk pillowcases, common momme weights include:
| Momme | General Character |
|---|---|
| 16 Momme | Lightweight and relatively thin |
| 19 Momme | Light to medium weight |
| 22 Momme | Balanced weight and durability |
| 25 Momme | Heavier and denser |
A higher momme number generally means more silk has been used per area of fabric.
However, higher does not automatically mean better.
A very heavy silk fabric may feel more substantial, while a lighter silk may feel more delicate and airy.
For everyday pillowcases, 22 momme offers a useful balance between softness, density, durability, and comfort.
This is one reason Muse & Airy uses 22 Momme Mulberry Silk for its pillowcases.
19 Momme vs. 22 Momme
A 19 momme pillowcase can still be a good option, particularly if you prefer a lighter fabric.
22 momme uses more silk by weight and generally feels slightly denser and more substantial.
For a product that is used and washed regularly, that additional fabric weight can be useful.

4. What Does Grade 6A Silk Mean?
You may also see silk products described as Grade 6A.
This term refers to the grading of raw silk quality and is commonly used by silk manufacturers and brands to describe higher-grade silk fibers.
It is important, however, not to confuse silk grade with momme.
They describe different things:
Grade 6A relates to the quality classification of the silk fiber.
22 Momme describes the weight and density of the finished silk fabric.
A pillowcase can therefore be described as both:
22 Momme + Grade 6A Mulberry Silk
These specifications complement each other rather than replacing one another.
When evaluating a pillowcase, you should still consider the finished product as a whole—including weaving, stitching, closure, and construction.
5. Check Whether the Pillowcase Is Double-Sided Silk
This is one detail that is easy to overlook.
Not every silk pillowcase is necessarily made from silk on both sides.
Some products use silk on the sleeping surface and another material on the reverse.
A double-sided silk pillowcase uses silk fabric on both sides.
This means that whichever side of the pillowcase you sleep on, your face and hair remain in contact with silk.
It also creates a more consistent look and feel throughout the product.
At Muse & Airy, our silk pillowcases use double-sided 22 momme mulberry silk rather than a silk-front, alternative-fabric-back construction.
When comparing products, check the description carefully instead of assuming that “silk pillowcase” automatically means both sides are silk.
6. Look at the Closure
The closure may seem like a small detail, but it affects both appearance and everyday use.
Common pillowcase closures include:
Envelope Closure
A flap of fabric keeps the pillow inside.
It is simple and avoids hardware, although the pillow can occasionally shift depending on the design.
Zipper Closure
A zipper keeps the pillow securely inside the pillowcase.
For silk pillowcases, a hidden zipper can provide a clean appearance while helping prevent the pillow from slipping out during the night.
The zipper itself should be neatly installed and should not feel bulky or exposed around the sleeping surface.
Muse & Airy pillowcases use a hidden zipper closure for this reason.
7. Choose the Correct Size
Do not assume every silk pillowcase fits every pillow.
Always check the actual dimensions.
For example, Muse & Airy’s Queen pillowcase measures:
20 × 30 inches / 51 × 76 cm
Measure your existing pillow before ordering if you are unsure.
A pillowcase that is too small may compress the pillow and affect its shape, while one that is much too large may feel loose.
Also remember that naming conventions such as Standard, Queen, and King can vary between countries and brands.
The dimensions are therefore more reliable than the size name alone.
8. Pay Attention to the Feel and Finish
Good silk should feel smooth and fluid, but “extremely shiny” is not necessarily a sign of higher quality.
Natural silk usually has a softer, more dimensional sheen rather than the highly reflective appearance often associated with some synthetic satin fabrics.
When evaluating silk in person, look for:
- Smooth surface
- Even color
- Consistent weaving
- Clean stitching
- Minimal loose threads
- Natural luster
- No strong chemical odor
Online, high-resolution close-up photographs can help, although specifications and transparency from the brand are equally important.
9. Think About Color Practically
Color is mostly a personal preference, but lighter and darker silk shades behave differently in everyday use.
Light colors can create a clean, calm bedroom aesthetic, while deeper colors may hide minor marks more easily.
Muse & Airy currently focuses on understated, sleep-friendly tones including:
- Pearl White
- Silver Gray
- Champagne
Rather than choosing solely based on trends, consider which color will work naturally with your existing bedding.
10. Check the Care Instructions Before Buying
Silk is durable when cared for properly, but it should not be treated exactly like cotton bedding.
Before buying, check whether the brand provides clear washing instructions.
Typical silk care includes:
- Use cool or lukewarm water
- Use a gentle detergent suitable for silk
- Choose a delicate cycle if machine washing is permitted
- Avoid chlorine bleach
- Avoid high heat
- Air dry when possible
- Avoid prolonged direct sunlight while drying
A silk pillowcase that fits your real washing routine is more useful than one you are afraid to wash.

11. Look Beyond Marketing Claims
Silk pillowcases are often marketed with dramatic beauty claims.
A more useful way to evaluate them is to focus on their actual material properties.
Silk has a naturally smooth surface and creates relatively low friction against the hair and skin compared with many rougher fabrics.
That smooth contact is one of the main reasons people enjoy sleeping on silk.
However, a pillowcase should not be treated as a medical or skincare treatment.
Think of silk as part of a comfortable sleep environment rather than a replacement for skincare, haircare, or professional treatment.
12. Check Brand Transparency
Specifications should be easy to find.
Before buying, look for brands that clearly explain:
- Silk composition
- Momme weight
- Product dimensions
- Construction
- Closure type
- Washing instructions
- Shipping information
- Return policy
If a brand repeatedly uses words such as “luxury” or “premium” but provides very little technical information, it can be difficult to understand what you are actually buying.
Clear specifications make comparison much easier.
Silk Pillowcase Buying Checklist
Before adding a silk pillowcase to your cart, ask:
- Is it actually 100% silk?
- Is the silk mulberry silk?
- What is the momme weight?
- Is it silk on both sides?
- What are the actual dimensions?
- How does it close?
- Are care instructions provided?
- Does the brand clearly explain its materials and construction?
If you can answer those questions, you are already in a much better position to compare products.
So, What Is a Good Momme for a Silk Pillowcase?
For most people, 19–25 momme is a practical range for a silk pillowcase.
A lighter 19 momme fabric can feel airy and delicate.
A heavier 25 momme fabric feels denser and more substantial.
22 momme sits comfortably between the two, which is why it has become a popular choice for premium everyday silk pillowcases.
At Muse & Airy, we chose 22 momme Grade 6A mulberry silk because it offers the balance we wanted between softness, fabric weight, durability, and everyday comfort.
Frequently Asked Questions
Is 22 momme good for a silk pillowcase?
Yes. 22 momme provides a good balance of density, softness, and durability for regular use.
Is 25 momme better than 22 momme?
Not necessarily. 25 momme is heavier, but personal preference matters. Some people prefer the slightly lighter feel of 22 momme.
Is mulberry silk the same as satin?
No. Mulberry silk describes a type of silk fiber. Satin describes a weave and can be made from silk, polyester, or other fibers.
Is 6A silk better than 22 momme silk?
They cannot be directly compared. Grade 6A describes silk quality classification, while momme describes fabric weight.
Should a silk pillowcase be silk on both sides?
It does not have to be, but a double-sided silk construction provides the same silk surface whichever side of the pillowcase you use.
How often should I wash a silk pillowcase?
This depends on personal use and your normal bedding routine. Regular washing is appropriate as long as the silk is washed gently and according to the care instructions.
A Better Pillowcase Starts With Better Information
Choosing a silk pillowcase does not need to be complicated.
Start with the fundamentals:
real silk, appropriate momme weight, clear construction, correct sizing, careful finishing, and realistic care instructions.
Once you understand those details, it becomes much easier to tell the difference between two products that may look almost identical on a screen.
At Muse & Airy, we believe good sleep products should be simple to understand—and comfortable enough to become part of your everyday routine.
