Why a 20 x 20 Pillow Insert Is Necessary
From my experience, having a 20 x 20 pillow insert is absolutely essential for creating the perfect pillow. It provides just the right amount of fullness and support, making my pillows look plush and inviting rather than flat or saggy. When I use a properly sized insert, my pillow maintains its shape throughout the day, which makes my living space feel cozy and well put together.
Another reason I find a 20 x 20 insert necessary is the versatility it offers. This size fits perfectly into many decorative pillow covers I own, allowing me to easily switch up my décor without worrying about awkward fits or bunching fabric. Overall, the right pillow insert not only enhances comfort but also elevates the aesthetic of any room, making it a small investment with a big impact.
My Buying Guides on 20 X 20 Pillow Insert
When I decided to upgrade my throw pillows, I quickly realized that choosing the right 20 x 20 pillow insert makes all the difference. Here’s what I learned through my experience to help you pick the perfect insert for your needs.
Understanding the Size
The 20 x 20 pillow insert refers to the dimensions in inches — 20 inches by 20 inches square. I found that getting the exact size is important because a slightly smaller insert can leave your pillow cover looking flat and limp, while a bigger one can make it look overstuffed and stretched. I usually look for inserts that match the pillow cover size or are just a little larger (like 21 x 21) for a plump, full look.
Choosing the Right Fill Material
There are several fill options for pillow inserts, and each feels different to me:
- Polyester Fiberfill: This is the most common and affordable. It’s soft and lightweight but can flatten over time. I use it for decorative pillows that don’t get heavy use.
- Down or Feather: These inserts are super soft and luxurious. I love how they feel plush and mold to my shape, but they require fluffing and are pricier. Also, if you have allergies, this might not be the best choice.
- Memory Foam: Provides firm support and keeps shape well. I prefer these for lumbar or support pillows rather than decorative ones.
- Down Alternative: A good middle ground with softness like down but hypoallergenic and easier to maintain.
Density and Firmness
I learned that the firmness depends on how densely the insert is filled. For decorative pillows, I like a medium to firm insert so the pillow looks full and maintains shape. If the insert is too soft, the pillow cover can look saggy. For pillows meant for comfort or support, a softer or memory foam insert works better.
Cover Material and Care
I always check if the pillow insert cover is removable and washable. Polyester covers are common and easy to clean. Some inserts come with a cotton or microfiber cover, which feels nicer but may require gentle care. I prefer inserts where I can unzip and wash the cover to keep things fresh.
Durability and Longevity
Since pillow inserts get a lot of use, I look for inserts with double-stitched seams to avoid leaks and flattening. Higher-quality fiberfill or down inserts last longer without losing shape. I’ve found that spending a little more upfront saves me from replacing inserts frequently.
Price Considerations
Budget plays a role in my decision. Polyester inserts are the most affordable, usually under $10-$15. Down or down alternative inserts typically cost more but feel more luxurious. I balance price with quality depending on whether the pillow is purely decorative or for everyday use.
Allergy Concerns
If you’re sensitive to allergens like feathers, I suggest going for hypoallergenic inserts such as polyester fiberfill or down alternative. I’ve had family members with allergies, so choosing these options keeps everyone comfortable.
Where to Buy
I’ve found great inserts at home goods stores, online marketplaces like Amazon, and specialty bedding shops. Reading customer reviews helps me verify the quality and firmness before buying.
Final Tips from My Experience
- Always measure your pillow cover before buying.
- Consider buying one insert first to test firmness and size.
- Fluff your pillow inserts regularly to maintain shape.
- Don’t hesitate to invest a bit more for better quality inserts if you want long-lasting pillows.
I hope my buying guide helps you find the perfect 20 x 20 pillow insert that makes your pillows look and feel amazing!
