How to Choose the Best 21x21 Cushion Covers for Your Patio

Having comfortable, stylish outdoor furniture can transform your patio, deck, or balcony into an inviting oasis for relaxation and entertainment. One easy way to update the look of your existing patio seating is by investing in new cushion covers. But not all cushion covers are created equal.

Cushions exposed to the elements can become faded, stained, and weathered over time. Protecting them with fitted cushion covers will extend their lifespan and keep them looking fresh. Covers can also allow you to change up colors and patterns to match your style. Read on for tips to select durable, well-fitting 21x21 cushion covers that enhance your furniture while sheltering the cushions inside.

Measure Your Existing Cushions

The first step when shopping for new covers is to carefully measure your current cushions. This allows you to order covers tailored to properly fit them. Standard 21x21 inch cushion covers are designed for square cushions measuring 21 inches on each side.

Use a soft tape measure to check both the width and length. Measure across the front and back of the cushion, then side to side. For the most accurate sizing, measure in multiple spots and use the largest dimensions. Round up to the nearest whole number if your cushion size falls between standard sizes.

If your cushions are an odd shape or oversized, you may need to size up or custom order covers. Manufacturers usually provide sizing charts to help you select the right cover dimensions for a great fit.

Tips for Measuring Oversized or Irregular Cushions

• Add 1-2 inches if cushions are overstuffed
• Size up for loose back pillows
• Select rectangular covers for elongated cushions
• Consider custom covers for unique shapes/sizes

Consider Materials and Construction

Outdoor cushion covers are made from solution-dyed acrylic, polyester, vinyl, or olefin fabrics. Each material has unique properties to weigh when making your choice.

Solution-dyed acrylics provide vivid, fade-resistant colors that withstand sun and water exposure. Polyester blends offer strength and stretch, while vinyls are waterproof and easy to clean. Olefins are mildew-resistant, quick-drying, and breathable in hot weather.

Look for covers made with UV-treated fabrics that block harsh sun rays. Backings coated in water-resistant finishes prevent moisture from seeping in. Tightly woven fabrics repel stains from dirt, food, and grease.

Double-stitched seams add structural integrity. Piping helps edges hold their shape. Straps with plastic buckles allow you to tighten covers for a snug fit. Zipper closures should glide smoothly and be made of rust-resistant metal.

Key Construction Features

• Fade and mildew resistant fabrics
• UV protection
• Waterproof coatings and backing
• Reinforced, double-stitched seams
• Durable, rust-resistant zippers
• Adjustable, click-close straps

Evaluate Weather Resistance

Since cushion covers live outside and endure sun, wind, rain, and dirt, they must be engineered to withstand the elements. Look for durable performance features when comparing cushion cover options.

Waterproof vinyls and acrylics with a high concentration of pigment provide optimal sun protection. Make sure any fabric you choose blocks UV rays to prevent fading. Backings treated with water repellants prevent rain and snow from soaking into cushions.

Choose covers with ventilation eyelets if you live in a hot, humid climate. This allows air to circulate and moisture to escape. Fully waterproof materials can trap condensation inside.

Check product details to confirm covers can tolerate sun exposure, rainfall, wind gusts, and other weather conditions in your region. Covers that endure the elements will keep your cushions protected.

How to Assess Weather Resistance

• Look for UV protection specifications
• Confirm waterproof and stain guard coatings
• Check for ventilation eyelets
• Read product testing details
• Choose covers suitable for your climate

Choose Colors and Patterns

An easy way to update your patio's look is by switching your cushion covers to new colors and prints. Choose hues and patterns that coordinate with your existing furniture and outdoor decor.

Solid colors in neutral shades like tan, gray, and brown are versatile pairings for any style. Bold tones like turquoise or crimson make your cushions stand out. Or opt for two-toned reversible covers to enjoy a new color combo.

Vivid patterns and prints work well for cushions. Florals, geometrics, stripes, and abstract prints infuse personality and style. Mix and match colors and designs for a collected look.

Keep maintenance in mind too. Darker colors like navy blue help hide dirt and stains that inevitably find their way onto outdoor cushions. Lighter cream or white looks pretty but requires more frequent washing.

Tips for Selecting Colors and Patterns

• Choose colors that complement your decor
• Mix and match solids, prints and textures
• Consider darker colors to disguise dirt
• Add pops of color with bold patterns
• Opt for reversible two-toned covers

Assess Ease of Use

From securing the covers to removing them for cleaning, convenience factors are important for cushions used daily. Evaluate how easy covers are to access, adjust, and maintain when making your selection.

Zipper closures make it simple to put covers on and take them off as needed. Straps that click and lock into place allow you to adjust and ensure a custom fit.

Zipper garages keep closures hidden and prevent scratches when closed. Piping with mesh backing adds structure while improving airflow. Handy features like these make covers more user-friendly.

Check the product label for care and washing guidelines. Many covers can be spot cleaned or machine washed. Proper maintenance keeps them looking fresh season after season.

Usage and Care Considerations

• Secure zippered access
• Adjustable straps for custom fit
• Ventilation piping
• Zipper garages protect furniture
• Spot clean and machine wash options

Compare Brands and Prices

Once you have identified the ideal fabric, features, and sizing, it's time to compare options and prices. Outdoor cushion covers range from budget-friendly to premium designer.

Well-known brands like Montlake, Highland Dunes, and Pillow Perfect offer good quality at reasonable price points. Higher end brands like Pendleton and Sunbrella come at luxury prices but last for years.

Better quality materials and construction warrant higher prices but also equate to longer-lasting covers. Consider lifetime cost versus upfront cost when evaluating different covers.

Many retailers sell covers individually or in complete cushion sets. Peruse consumer reviews to learn how specific covers wear over time. Opt for brands that back their products with warranties.

Factors to Weigh

• Price differences by material used
• Durability of budget vs. premium covers
• Quality and length of warranties
• Individual covers or full sets
• Consumer reviews on performance

Be Sure of Proper Fit

With an abundance of sizing options like 20x20, 22x22, and 24x24, it can get confusing finding the right cushion cover dimensions. To ensure a tailored fit, double check your exact measurements before purchasing.

Covers sized too small will be tight and strained. Oversized covers can look sloppy and saggy. Measure carefully for the best fit. Keep in mind square and rectangular cushions require matched cover shapes.

If your cushions are slightly overstuffed, add an extra inch or two to the covers for a bit more wiggle room. You can always tighten straps for a snugger fit. But covers too tight won't properly enclose cushions.

Avoid These Pitfalls

• Not measuring accurately
• Buying the wrong shape
• Sizing too small
• Purchasing oversized covers
• Forgetting about fill

Investing in a set of tailored, weather-resistant cushion covers lets you enhance your patio, porch, or deck with updated style and comfort. Follow this guide to select durable covers that add beauty and protect your cushions.

Measure precisely for a custom fit. Compare materials and features that make covers durable and easy to use. Choose colors, patterns, and textures that coordinate with your existing decor. And be sure to match the right cover dimensions to your cushions.

You'll enjoy comfortable outdoor seating for a long time with high quality cushion covers. Your open air living room will become a true oasis you love lounging in.
