Gray outdoor throw pillows can add neutral color to patio seating, but the right choice depends on whether you need complete pillows, replacement covers, or inserts. The FUNHOME set is best for shoppers wanting two gray striped pillows with inserts, while Unimatta suits buyers who need four water-repellent pillows. MIULEE and NiNi ALL are cover-only options; Atarashi provides white inserts rather than gray pillows.
| Product | Best For | What’s Included |
|---|---|---|

| FUNHOME Gray Stripe | Ready-to-use striped accents | Two pillows with inserts |
| Unimatta Gray Stripe | Furnishing several seats | Four pillows with inserts |

| NiNi ALL Grey Covers | Waterproof solid covers | Two covers; inserts not included |
MIULEE Light Grey Outdoor Covers

These 18-by-18-inch MIULEE covers are a straightforward option for a light gray patio color scheme. The 100% polyester fabric is described as waterproof and designed to resist water and moisture. Their solid color can pair with common outdoor furniture finishes such as beige, white, wood, and rattan.
Best for: Buyers who want simple, light gray covers to coordinate with existing patio cushions. The solid design is the reason to choose this set over a striped style.
Keep in mind: The listing describes pillow covers, not complete pillows. The supplied details do not specify whether inserts are included, so check the package listing before ordering if you need filled cushions.
FUNHOME Gray Stripe Pillow Set

This set includes two 18-by-18-inch gray striped pillows with soft PP cotton filling. The spun polyester fabric is described as durable and water resistant against splashing. The covers have a hidden zipper for inserting or removing the filling, and the listing states that the fabric has 500-hour UV protection to help resist fading.
Best for: Buyers who want two filled, patterned pillows rather than separate covers and inserts. Choose this set for striped styling and the stated UV-protection feature.
Keep in mind: The filling arrives vacuum-packed and needs time to expand. The product description refers to resisting splashes; it does not establish that the pillows are fully waterproof.
Unimatta Four-Pillow Gray Stripe Set

Unimatta’s set provides four 18-by-18-inch pillows with gray stripe styling. The 100% polyester fabric has a water-repellent coating intended to help protect against splashes and water blotting. The listing describes the pillows for both outdoor and indoor spaces, including patios, gardens, balconies, beds, and sofas.
Best for: Buyers furnishing multiple chairs or a larger seating area who want a coordinated set of four filled pillows. It offers more pieces than the two-pillow options in this guide.
Keep in mind: The stated protection is water repellent, not a guarantee of complete waterproofing. The seller also notes that hand-cutting and sewing may result in a 1–2 cm size deviation.
Atarashi Waterproof Pillow Inserts

Atarashi sells a set of two 20-by-20-inch inserts, not gray finished pillows. Each insert has a waterproof cover and polyester filling. The listing describes the inserts as soft, fluffy, and supportive, with elasticity intended to provide back support. It recommends pressing and squeezing them to restore their shape.
Best for: Buyers who already own 20-inch gray outdoor covers and need inserts. Choose these when you want to fill covers separately rather than buy a complete pillow set.
Keep in mind: The inserts are white and do not include gray decorative covers. Confirm your cover’s dimensions before buying; these are 20 inches, not 18 inches.
NiNi ALL Grey Waterproof Covers

This set contains two 18-by-18-inch solid gray covers. The listing describes the material as waterproof and says its coating creates a water-beading effect. A hidden zipper at the back allows the cover to be removed for inserting or taking out a cushion, while the zipper design is intended to avoid scratching.
Best for: Buyers who want solid gray covers with a stated waterproof coating and already have suitable inserts. The hidden zipper makes the covers easier to put on and remove.
Keep in mind: These are covers only; inserts are not included. The seller notes a possible 1–2 cm measurement deviation from hand-cutting and sewing.
Buying Guide: How To Choose Gray Outdoor Throw Pillows
Do you need complete pillows or covers?
Complete pillows include both the outer fabric and filling. FUNHOME and Unimatta are listed as pillow sets with inserts. MIULEE and NiNi ALL are cover options, so plan to use or purchase compatible inserts. Atarashi supplies inserts only and requires separate covers.
Should you choose waterproof or water-resistant fabric?
Check the exact wording in the product description. MIULEE and NiNi ALL describe their covers as waterproof, while FUNHOME describes water resistance against splashing and Unimatta specifies a water-repellent coating. These terms do not mean the same thing, and the listings do not promise protection in every weather condition. Bring pillows inside or protect them when not in use if weather exposure is a concern.
What size should you buy?
Match the pillow or insert dimensions to the cover and furniture. Four options here are sized at 18 by 18 inches, while the Atarashi inserts measure 20 by 20 inches. Check the product measurements before ordering, especially when replacing existing cushions.
Is solid gray or gray stripe better?
Solid light gray covers provide a simple neutral accent, while striped sets add a visible pattern. Consider the color and pattern of your outdoor furniture and other textiles. A solid cover can be easier to coordinate; a stripe can create more contrast.
Frequently Asked Questions
Which option includes the most pillows?
Unimatta includes four 18-by-18-inch gray striped pillows, making it the largest complete pillow set listed here.
Which products include pillow inserts?
FUNHOME and Unimatta are listed as complete pillows with filling. Atarashi includes two inserts but no decorative covers.
Are the MIULEE and NiNi ALL products complete pillows?

Can I use 20-inch inserts in an 18-inch cover?
The product details do not confirm a fit. Match insert and cover measurements, or check the cover maker’s guidance before combining different sizes.
Are these pillows suitable for leaving outside in all weather?
The listings describe water-resistant, water-repellent, or waterproof materials, but do not establish that every complete pillow can remain outdoors in all weather. Follow the product care instructions and limit prolonged exposure when appropriate.
