My Buying Guides on 12 X 20 Pillow Insert
When I first started shopping for a 12 x 20 pillow insert, I realized there are several important factors to consider to find the perfect one. Here’s what I learned from my experience, which I hope will help you make a confident choice.
Understanding the Size
The 12 x 20 measurement refers to the dimensions of the pillow insert in inches—12 inches high and 20 inches wide. I found it crucial to measure my pillow covers first to ensure the insert would fit snugly without being too loose or too tight. A proper fit makes the pillow look full and comfortable.
Choosing the Right Filling Material
There are different types of filling materials available, and I had to decide which suited my needs best:
- Down or Feather: Soft and luxurious, but can be pricier and may cause allergies for some.
- Polyester Fiberfill: Affordable, hypoallergenic, and easy to maintain. This was my go-to for everyday use.
- Memory Foam: Offers firm support but can be heavy and less fluffy.
I personally preferred polyester fiberfill because it balanced comfort, price, and ease of care.
Checking for Quality and Durability
I looked for inserts with double-stitched seams to prevent the filling from escaping. A high-quality fabric cover, like cotton or a cotton blend, also made a difference in durability. After all, I wanted my pillows to last through frequent use and washing.
Considering Loft and Firmness
The loft (height) and firmness of the insert affect how the pillow looks and feels. I chose a medium loft because it gave my pillows a nice, plump appearance without being too stiff or too flat.
Maintenance and Care
Since pillow inserts can collect dust and allergens, I checked if they were machine washable or if they required spot cleaning only. I found that inserts with removable covers or easy-care materials saved me time and effort.
Budget and Value
Price varied widely depending on the fill and brand. I set a budget but was willing to spend a little more for better quality. Sometimes, investing in a durable insert meant I didn’t have to replace it frequently.
Final Thoughts
Buying a 12 x 20 pillow insert isn’t just about size—it’s about comfort, quality, and matching your style. By paying attention to these details, I found inserts that made my pillows look inviting and feel cozy. I hope my guide helps you find the perfect pillow insert for your home!
