As autumn turns towards winter, many UK homeowners start thinking about how to protect their gardens, patios and outdoor seating areas. Rain, cold temperatures, fallen leaves and long periods without use can all make outdoor furniture harder to maintain.
Garden sofas, rattan chairs, patio tables and outdoor cushions can be particularly vulnerable if they are left exposed without suitable preparation.
The good news is that preparing your garden furniture for winter does not have to be complicated. A combination of proper cleaning, dry storage, suitable furniture covers and occasional inspections can help keep your outdoor space in better condition until spring.
In this guide, we explain how to prepare different types of garden furniture, choose suitable winter covers, prevent moisture from becoming trapped and avoid common storage mistakes.

1. Clean Your Garden Furniture Before Winter
Before putting furniture away or covering it for the colder months, give it a proper clean.
Leaves, soil, dust, bird droppings and other outdoor debris can collect around furniture frames and joints. Covering furniture without removing this dirt may make cleaning more difficult later.
The cleaning method should depend on the material.
Wooden Garden Furniture
Wooden garden furniture may benefit from cleaning and suitable outdoor wood treatment before winter storage.
Remove loose dirt using a soft brush and clean the surface with a product suitable for the particular type of wood.
Hardwood furniture, including teak and eucalyptus, may benefit from an appropriate outdoor wood oil, following the manufacturer's instructions.
Rattan and Wicker Furniture
For synthetic rattan furniture, use a soft brush or cloth to remove dirt from the woven sections.
Pay attention to corners and underneath the seating area, where leaves and dust can collect.
Avoid aggressive cleaning methods unless the furniture manufacturer confirms they are suitable.
Metal Garden Furniture
Inspect metal frames for scratches, loose fittings and damaged protective finishes.
Clean the surfaces using an appropriate mild cleaning method and allow them to dry fully.

2. Store Outdoor Cushions and Fabrics Separately
One of the simplest ways to prepare a garden seating area for winter is to remove cushions and other soft furnishings.
Outdoor sofa cushions, chair pads and decorative textiles can retain moisture if they are left outside for extended periods.
Before storing them\:
- Remove loose dirt and debris.
- Clean according to the manufacturer's care instructions.
- Allow the cushions to dry completely.
- Store them in a dry, sheltered location.
- Avoid placing them directly on damp floors.
A garage, dry shed or suitable indoor storage area can be useful.
If you have limited storage space, consider a suitable outdoor cushion storage box. The important point is to keep the contents dry and avoid sealing damp textiles inside.
JYSK also recommends storing garden cushions and textiles in a dry, sheltered place before the off-season. jysk.co.uk
3. Choose the Right Winter Garden Furniture Covers
If your garden furniture cannot be moved indoors, a suitable outdoor furniture cover can provide an additional protective layer.
However, not every cover is suitable for every type of furniture.
Think about the following features before choosing one.
Waterproof or Water-Resistant Materials
Outdoor furniture covers are available in different materials and constructions.
Some use coated polyester or Oxford fabric, while others use lighter protective materials.
Check the individual product description carefully to understand its stated water-protection level.
Do not assume that every cover described as water-resistant will provide the same protection as a fully waterproof design.
Heavy-Duty Construction
For furniture that remains outside throughout winter, consider the fabric construction, stitching and overall suitability for outdoor use.
A thicker material may be useful in exposed garden areas, although thickness alone does not guarantee better performance.
Ventilation
Ventilation is an important consideration.
A cover that allows some air circulation can help reduce the risk of moisture becoming trapped underneath.
Look for air vents or other ventilation features, particularly if the furniture will remain covered for long periods.
Secure Fastenings
Wind can catch loose fabric and cause the cover to move.
Elasticated edges, adjustable drawstrings, straps and buckles can help keep the cover in position.
The individual design matters, so check which fastening features are actually included.
4. How to Measure Outdoor Furniture Covers Correctly
Choosing the correct dimensions is just as important as selecting the material.
A cover that is too small may not reach the lower sections of your furniture. An excessively large cover may flap in the wind or gather around the base.
Use a flexible tape measure and record the dimensions in centimetres.
Measuring an Outdoor Sofa
Measure\:
- Overall width from the outside of one armrest to the other.
- Overall depth from the front to the back.
- Height from the ground to the highest point.
- Additional sections such as chaise extensions or unusual arm shapes.
Measuring Garden Chairs
For individual garden chairs, record the overall height, width and depth.
If the chairs have arms or unusually shaped backs, include these in your measurements.
Measuring a Complete Patio Set
For a combined dining or seating arrangement, decide whether you want one cover for the entire set or separate covers for individual furniture pieces.
Measure the overall arrangement, including any table extensions or projecting chair sections.
Leave enough room for fitting and removal, but avoid choosing a size so large that the cover becomes difficult to secure.
SofaCoverUK offers different outdoor cover shapes and size options, so compare your measurements against the actual product specifications before ordering.
5. Why Ventilation Matters During Winter Storage
One common mistake is assuming that a completely sealed cover is always the best choice.
Moisture can collect underneath a cover, particularly when furniture is covered while damp or when there is insufficient airflow.
This can contribute to condensation, mould and mildew.
To reduce this risk\:
- Always clean and dry furniture before covering it.
- Look for suitable air-vented cover designs.
- Avoid allowing fabric to sit tightly against flat wooden surfaces.
- Check underneath the cover occasionally.
- Remove standing water where it has collected.
- Allow furniture and covers to air when conditions are suitable.
For wooden furniture, maintaining some space between the cover and flat surfaces can be particularly useful.
Harbour Lifestyle's furniture-cover care guidance also recommends breathable, air-vented covers, correct sizing, secure fastenings and completely dry furniture before covering. help.harbourlifestyle.co.uk
6. Prevent Water from Pooling on Your Furniture Cover
Another problem during winter is standing water.
When rain collects in a dip in the cover, the additional weight can pull the material down further and create an even deeper pool.
This is particularly relevant for large garden sofas and rectangular patio furniture.
Consider these practical steps\:
- Choose a cover that matches the overall furniture shape.
- Avoid excessive loose material around the top.
- Where appropriate, use a suitable support structure to create a gentle slope.
- Check the cover after heavy rainfall.
- Remove accumulated water safely rather than allowing it to remain for long periods.
Do not place sharp objects or unsuitable supports underneath the cover, as these could damage the material.
A well-positioned cover should help rainwater drain away rather than allowing it to collect in one area.
7. Secure Your Garden Furniture Covers Against Wind
Winter weather can be unpredictable, especially in open gardens and exposed patio areas.
A loosely fitted cover may move around during windy conditions, exposing furniture or rubbing against its surfaces.
When fitting a cover\:
- Position it evenly over the furniture.
- Check that the corners are properly aligned.
- Fasten all available buckles or straps.
- Tighten the drawstring where provided.
- Check the lower edges for excessive movement.
- Inspect the fastening points after particularly windy weather.
Avoid attaching straps to fragile furniture components.

8. Different Furniture Needs Different Types of Covers
The best cover depends on the furniture you want to protect.
Outdoor Sofa Covers
Garden sofas and larger patio seating arrangements need covers that accommodate their full dimensions.
An ordinary indoor sofa slipcover is not a substitute for a purpose-designed outdoor furniture cover.
Explore the Outdoor Sofa Cover collection for available options.
Garden Chair Covers
Individual garden chairs may require smaller covers with suitable backrest and seat dimensions.
If you have several chairs around a dining table, consider whether separate covers or a combined patio-set cover would be more practical.

Garden Sofa Covers
For larger garden seating arrangements, check whether the cover accommodates the complete shape, including any corner or extended seating sections.

9. Winter Furniture Cover Maintenance Checklist
Putting a cover on once does not mean you can forget about your furniture until spring.
Occasional checks can help you identify problems before they become more serious.
Use this simple maintenance routine\:
| Frequency | Recommended task |
|---|---|
| Before winter | Clean and dry furniture |
| Before covering | Remove outdoor cushions and textiles |
| After heavy rain | Check for standing water |
| After strong winds | Check straps and fastenings |
| During winter | Inspect for trapped moisture |
| Every few weeks when practical | Check cover condition and fit |
| Before spring | Remove covers and inspect furniture |
The schedule should be adapted to the exposure of your garden and the manufacturer's care instructions.
If you notice damage, repair or replace the cover as appropriate rather than relying on a damaged covering throughout the season.
