Why 18 By 18 Inch Pillow Inserts is Necessary
As someone who loves to decorate and constantly update the look of my living space, I have come to realize the importance of having 18 by 18 inch pillow inserts. At first, I used to think that any size of pillow insert would do as long as it fit into the pillow cover. However, after some trial and error, I have come to understand why the 18 by 18 inch size is necessary.
Firstly, the 18 by 18 inch size is considered a standard size for throw pillows. This means that most pillow covers are designed to fit this specific size. Using a smaller or larger insert can result in an ill-fitting and unappealing appearance. With an 18 by 18 inch insert, you can easily find a variety of stylish covers that will fit perfectly.
Another reason why 18 by 18 inch pillow inserts are necessary is for achieving a fuller and plusher look for your pillows. A larger insert will fill out the corners and edges of the pillow cover, creating a more visually appealing shape. On the other hand, a smaller insert will result in a flatter and less inviting appearance.

My Buying Guide on ’18 By 18 Inch Pillow Inserts’
When it comes to decorating your home, one of the easiest ways to add a pop of color and personality is by using throw pillows. And while there are endless options for pillow covers, finding the right pillow insert is equally important. As someone who has spent countless hours researching and trying out different pillow inserts, I have compiled this buying guide to help you make an informed decision when purchasing 18 by 18 inch pillow inserts.
What are 18 by 18 inch pillow inserts?
Before diving into the buying guide, let’s first understand what exactly are 18 by 18 inch pillow inserts. These are square-shaped inserts that measure 18 inches by 18 inches, making them a standard size for most decorative throw pillows. They are filled with either synthetic or natural materials such as polyester, down feathers, or foam.
Types of Pillow Inserts
There are three main types of pillow inserts based on the filling material – polyester-filled, down-filled, and foam-filled.
1. Polyester-filled: These inserts are made with synthetic fibers that mimic the softness and fluffiness of down feathers. They are budget-friendly and hypoallergenic, making them a great option for those with allergies.
2. Down-filled: These inserts contain natural down feathers from ducks or geese. They provide a luxurious feel and tend to be more durable than polyester-filled ones. However, they can be expensive and may trigger allergies in some individuals.
3. Foam-filled: These inserts use foam as the filling material and provide firm support for your pillows. They do not require frequent fluffing like other types of inserts but may not be as comfortable as down or polyester ones.
Factors to Consider
When looking for an 18 by 18 inch pillow insert, here are some factors to keep in mind:
1. Filling Material: The type of filling material will determine the softness, durability, and price of the insert.
2. Fill Power: For down-filled inserts, look for ones with a higher fill power (600-800) as they tend to be more plump and long-lasting.
3. Cover Material: The cover material should be made from a breathable fabric such as cotton or microfiber to prevent overheating.
4. Weight: The weight of the insert will affect its firmness and support. If you prefer a soft and fluffy feel, go for lightweight options while heavier ones offer more firmness.
5. Care Instructions: Look for inserts that come with easy care instructions such as machine washable or dry clean only depending on your preference.
Where to Buy
Pillow inserts can be found at most home decor stores such as Bed Bath & Beyond or online retailers like Amazon or Wayfair. Be sure to read reviews from previous buyers before making a purchase to ensure quality.
Budget
The price of an 18 by 18 inch pillow insert can range from $10-$30 depending on the filling material and brand. It is essential to set a budget beforehand to narrow down your options.
Conclusion
When it comes to choosing the right pillow insert for your throw pillows, understanding the different types available along with considering factors like filling material, cover material, weight, care instructions, and budget will help you make an informed decision that meets your needs and preferences best.
