Match the cover size to your furniture's actual measurements
The most common mistake is buying a cover that looks big enough in the store or online, then finding it won't stretch over your chair or table. Before you shop, measure your furniture in three directions: width, depth, and height. For a dining table, measure the tabletop itself plus the height from ground to the underside of the top. For chairs, measure the seat width, the depth from front to back, and the height from ground to the top of the backrest. Write these numbers down—do not rely on memory.
When you look at a cover listing, the dimensions should be given in the same order. A cover marked "60 x 40 x 30" means 60 inches wide, 40 inches deep, and 30 inches tall. Check that the cover's dimensions are at least as large as your furniture in all three directions. Many covers come in a range of sizes—small, medium, large—rather than exact measurements, so look for the size chart that shows the actual inches. If your table is 48 inches wide and the "large" cover fits up to 50 inches, that is tight but workable. If it fits up to 45 inches, it will not close properly.
Key Takeaways
- Measure your furniture in width, depth, and height before shopping, and compare those numbers to the cover's actual dimensions, not just the size label.
- Fabric weight matters more than price: a 300-denier cover will last two to three seasons, while a 600-denier cover often lasts five or more years in most climates.
- Waterproof does not mean breathable—trapped moisture under a non-breathable cover can rot wood and cause mildew, so look for water-resistant fabric with ventilation.
- Ties, straps, or weighted hems keep covers from blowing off in wind, which is the main reason covers fail in the field.
- Your climate determines how much protection you need: a cover in a dry climate can be lighter than one in a wet or snowy region.
Understand fabric weight and what it means for durability
Fabric weight is measured in denier, a unit that tells you how thick and durable the material is. A 200-denier cover is thin and lightweight—it blocks some sun and light rain but tears easily and may not survive a full season of wind and weather. A 300-denier cover is the practical minimum for most patios; it resists tearing, sheds water reasonably well, and typically lasts two to three seasons. A 600-denier cover is heavy-duty and can last five years or longer, even in harsh climates.
The trade-off is weight and ease of handling. A 600-denier cover for a large table is genuinely heavy and awkward to fold and store. If you live in a mild climate with little wind and you plan to remove the cover in winter, a 300-denier cover is usually enough. If you live somewhere with strong winds, heavy rain, or snow, or if you leave the cover on year-round, step up to 400 or 600 denier. Check the product description—reputable manufacturers list the denier number. If a listing does not mention it, the cover is probably thin and not worth the money.
Choose water-resistant fabric with ventilation, not fully waterproof
A cover that is completely waterproof sounds like the right choice, but it creates a problem: water that gets trapped underneath has nowhere to go. Moisture collects under the cover, promoting mildew on the fabric itself and rot on wood furniture. A water-resistant cover sheds rain and snow but allows air to circulate, so any moisture that does get in can dry out.
Look for covers made from polyester or polypropylene with a water-resistant coating—these materials shed water while still breathing. Some covers have vents or grommets built in to allow air flow. If the product description says "100% waterproof" or "completely sealed," it is likely to trap moisture. The label should say "water-resistant" or "water-repellent." Test this yourself: if you can see light through the fabric when you hold it up, air can move through it, which is what you want.
Check for find fastening systems to prevent wind damage
A cover that blows off in the wind is useless, and wind is the number one reason covers fail in real use. Look for covers with one or more of these features: elastic hems that grip the furniture legs, drawstring closures that tighten around the base, straps with buckles or velcro, or weighted hems with sand pockets. The best covers have multiple attachment points—for example, corner ties plus a drawstring—so the cover stays put even in gusts.
If you live in a windy area, avoid covers that rely only on their own weight to stay in place. Test the fastening system by hand before you buy if possible. Pull on the straps or elastic to make sure they are sturdy and do not slip. Cheap velcro wears out after a few seasons, so if the cover uses velcro, check whether it is industrial-grade or standard. Ties should be sewn on securely, not glued.
Consider your climate and how long you will leave the cover on
A cover that works in Arizona may not work in Seattle, and a cover you remove every fall needs different features than one you leave on all winter. In dry climates with little rain or snow, a lighter, thinner cover is sufficient because the main threat is UV damage and dust. In wet climates, you need a heavier, more water-resistant cover because moisture is the enemy. In snowy climates, the cover must support weight without sagging or tearing.
If you remove the cover in winter and store it indoors, you can use a lighter-duty cover because it is not exposed to the harshest weather. If you leave the cover on year-round, choose a heavier denier and make sure the fastening system is very find—wind and snow load are both stresses a seasonal cover does not face. Some manufacturers make regional versions of the same furniture cover; a "winter" version is thicker and more robust than a "summer" version. Check whether the cover you are looking at is designed for your season and climate.
Look for reinforced seams and UV-resistant coating
Seams are the weak point in any fabric cover. A cover with single-stitched seams will split along the seams before the fabric itself tears. Look for double-stitched or triple-stitched seams, especially at the corners where stress concentrates. Some manufacturers reinforce seams with binding tape, which adds durability. The product description or photos should show this detail; if seams are not mentioned, assume they are standard single-stitched.
UV coating protects the fabric from sun damage and fading. Polyester and polypropylene are naturally somewhat UV-resistant, but a cover with added UV protection will last longer and maintain its color. This is most important if your patio gets full sun all day. The label may say "UV-resistant," "UV-protected," or "fade-resistant." This feature adds a small amount to the price but extends the cover's life by a year or two.
Compare covers for your specific furniture shape
Furniture comes in different shapes, and a generic rectangular cover does not fit everything. A round table needs a round cover, not a square one that bunches up. A sectional sofa needs a cover designed for that shape, or you may need multiple covers. Lounge chairs, benches, and oddly shaped pieces often have covers made specifically for them. Before you buy, confirm that the cover is designed for your furniture type, not just your furniture size.
Some manufacturers sell covers in sets—for example, a set that includes covers for a table, four chairs, and a bench. These sets are usually cheaper per piece than buying covers individually, but only if you need all the pieces. If you only need a table cover, buying the set wastes money. Check what is included in any bundle before you commit.
Frequently Asked Questions
Can I use the same cover for different furniture if the size matches?
Not reliably. A cover designed for a round table will not fit a rectangular one even if the dimensions are similar, because the shape is wrong. A cover for a chair may not work on a bench because the height and proportions are different. Use a cover made for your specific furniture type to may support it fits properly and stays find.
How often should I clean my patio furniture cover?
Rinse the cover with a garden hose two or three times a year to remove dust and debris. If you see mildew or stains, scrub gently with a soft brush and mild soap, then rinse thoroughly and let it dry completely before putting it back on. Do not use bleach or pressure washers, which can damage the fabric and coating.
Should I remove the cover in winter or leave it on?
If you live in a snowy climate, removing the cover in winter protects it from heavy snow load and ice damage. If you live in a mild climate with little snow, leaving the cover on year-round is fine as long as it is rated for that use. Check the manufacturer's instructions—some covers are designed for seasonal use only and will degrade if left on in harsh winter weather.
What is the difference between a cover and a storage bag?
A cover stays on the furniture outdoors and protects it from weather. A storage bag is used when you remove the furniture and store it indoors or in a shed. Storage bags are usually thinner because they do not need to resist weather, and they are designed to compress for compact storage. Do not use a storage bag as an outdoor cover.
Do I need to remove the cover to use the furniture?
Yes. A cover protects furniture when it is not in use. Remove it before you sit down or eat at the table. Leaving the cover on while using the furniture traps moisture and can damage both the cover and the furniture. Put the cover back on as soon as you are done.
