How to Fix Sagging Patio Chairs

Common Causes of Sagging Patio Chairs

Spending warm summer evenings on the patio with family and friends is one of life’s simple pleasures. But there’s nothing enjoyable about sagging patio chairs with lump cushions that provide little comfort or support. Before you can revive your worn outdoor furniture, it’s important to understand what’s causing it to sag in the first place.

Prolonged Exposure to Weather

Since patio chairs live outdoors year-round, they are subjected to harsh sun, rain, and fluctuating temperatures that can gradually degrade materials and cause sagging.

Sun Damage

The sun’s intense UV rays can fade and dry out fabric chair cushions and cause them to stretch and lose their shape over time. Prolonged sun exposure also deteriorates plastic strapping and makes wood frames crack and warp.

Moisture Damage

Rain, humidity, and dampness from morning dew leads to mildew buildup and moisture retention in cushion fillings. This added weight strains fabric and causes the fillings to compress permanently. Puddling water can also lead to rust and corrosion of metal chair frames.

Temperature Fluctuations

Frequent expansion and contraction of materials due to shifts between warm days and cool nights places stress on furniture. Sudden temperature drops can make plastic straps brittle so they snap under pressure. Big swings in humidity causes wood frames to swell and shrink.

Improper Cushion Care

If patio chair cushions aren’t properly maintained on a regular basis, they’ll eventually start to sag. Neglecting cushions shortens their usable lifespan.

Insufficient Filling

Cushions need to be well-filled and plump to provide comfort and support. Understuffed cushions that lack enough polyfill, foam, or other cushion materials compress too easily under body weight. This leads to permanent indentations and an uneven, sagging surface.

Poor Quality Cushion Materials

Cheap, low-density foam and polyfill cushion fillings get crushed down quickly with use. They permanently compact and can’t spring back to maintain cushion shape. Low quality fabric is also less resilient and prone to stretching out.

Failure to Flip/Rotate Cushions

Rotating cushions helps distribute wear evenly and extend their life. But leaving cushions in one position without flipping or turning them causes accelerated breakdown in those areas. The spot where you regularly sit will get compressed and concave first.

Normal Wear and Tear

With frequent use, patio chair cushions and frames gradually wear down even with proper care. Material breakdown is inevitable over time.

Loss of Elasticity in Fabric

The fibers in cushion fabric stretch out with prolonged use, causing the surface to sag. Over time, the material loses its ability to bounce back. Harsh weather and sun exposure speeds up loss of elasticity.

Compression of Cushion Fillings

Interior cushion fillings like foam and polyfill get compacted with the force of people sitting. They permanently flatten and can no longer provide adequate support. Soft fillings like down compress fastest.

Stretching of Straps and Webbing

The plastic strapping or fabric webbing on chair frames weakens and stretches from the cumulative effect of weight bearing down. This allows cushions and seating surfaces to sink lower.

Keeping your patio chairs out of the elements when not in use and practicing proper cushion care can slow wear and tear. But after seasons of use, sagging from age and deterioration is inevitable. Knowing what leads to sagging can help you determine the necessary fixes and refurbishments to revitalize worn patio furniture.

Quick Fixes for Sagging Patio Chairs

After years of use, it’s common for patio chairs to start sagging as cushion fillings compress and frames weaken. While sagging is inevitable, there are some easy DIY solutions to temporarily revive your worn outdoor furniture without fully refurbishing or replacing it. Quick fixes help extend the usable lifespan of aging patio chairs for another season or two.

Add Additional Cushion Filling

Plumping limp, flat cushions with extra fillings is a fast way to restore fullness and support. Just make sure to use fill materials suitable for outdoor use that won’t absorb moisture.

Open Seams and Add Polyfill, Foam Pieces, or Beans

Carefully rip open fabric seams on the underside of cushions using a seam ripper. Do this in an inconspicuous area that won’t be visible.
Stuff the interior with additional polyester fiberfill, cut up foam pieces, or polystyrene beans using a funnel or stuffing tool.
Polyfill adds softness while foam and beans provide firmer support. Use existing cushion fillings as a guide.
Once it’s filled sufficiently, hand sew the opening closed or use fabric glue.

Insert Cushion Inserts for Extra Support

Slice open an inconspicuous underside seam of the cushion cover.
Insert a fiberfill pillow or foam wedge cushion insert. This adds an extra interior layer of support.
Sew up the slit or use fabric glue to close the opening.

Use Furniture Lifters

Lifters placed under chair legs raise the overall height, taking pressure off of strained frames and cushions. This helps sagging seats until more permanent repairs can be done.

Place Lifters Under Legs to Raise Overall Height

Felt pads, plastic caps, or adjustable metal risers can be affixed to the bottom of chair legs to lift them. Start with a 1″ lift and increase if needed.

They must be uniformly sized to keep the chair level. Measure to determine necessary lift height.
Follow manufacturer instructions for attachment based on leg material (wood, metal, plastic).

Help Redistribute Chair Weight and Reduce Strain

The slight lift takes pressure off of tortured joints and materials by improving weight displacement. It helps alleviate strain that was causing loosening and sagging.

Tighten Loose Hardware

Checking for loose bolts and reattaching detached components provides more support to prevent sagging.

Tighten Bolts on Frame Joints

Inspect the underside of the chair. Use a socket wrench to tighten any loose bolts at frame joints.
If bolts are missing, replace them with new hardware of the same size.

Reattach Any Loose or Detached Webbing/Straps

Look for areas where plastic/fabric strapping has detached from the frame and reattach using outdoor-rated adhesive or ties.
For broken straps, remove damaged portions and knot intact areas together.

These quick and easy sagging solutions help extend the life of your patio chairs for a while longer before they require more intensive repairs and replacements. Use them to buy some extra summertime with your aging outdoor furniture.

Long-Term Solutions for Sagging Chairs

Quick fixes provide temporary relief, but sagging patio chairs eventually require more intensive repairs and replacements to fully restore them. Investing some time and money into long-term refurbishing lets you revive worn outdoor furniture and enjoy properly supportive seating for years to come.

Replace Cushions

Over time, even well-cared for cushions compress and sag. Replacing with new cushions restores fullness and comfort.

Measure Dimensions and Order New Cushions

Remove the old cushions and accurately measure length, width, and thickness.
Order replacement cushions in the same size from an outdoor furniture company. Provide them the dimensions.
For a custom fit, have new cushions made-to-measure by a fabricator.

Select High Density, All-Weather Cushion Materials

Look for cushions constructed with materials that resist weathering and permanent compression:

High density foam – Dense foam has fewer air pockets so it compresses less under body weight.
** Hollow polyfiber** – Hollow synthetic fibers provide cushioning without flattening.
Outdoor fabric – Acrylic or polyester fabric resists fading, staining, and mildew.
Waterproof liners – Liners prevent moisture absorption leading to mold and rot.

Repair Frame and Support Structures

Fixing loose joints and replacing corroded components repairs the underlying chair structure so it can properly support new cushions.

Reinforce Joints and Attach New Brackets

Tighten any wobbly joints and secure with weatherproof wood glue or epoxy.
Add support by attaching corner brackets and additional cross braces with rust-resistant screws.

Replace Any Broken or Rusted Components

Swap out broken wood or plastic pieces with new matching hardware.
Sand and repaint metal frames stripped by rust. Replace excessively corroded sections.

Refurbish Cushion Covers and Fabric

Protect refreshed interior cushions by recovering or replacing faded, brittle exterior fabric.

Sew New Covers or Replace Fabric as Needed

Make tailored new cushion covers if the old fabric is still intact enough to reuse as a pattern.
Completely recover cushions by removing old fabric and stapling on new material if existing covers are too far gone.

Use Marine Grade, UV-Resistant Outdoor Fabric

Outdoor acrylic or polyester fabric is durable and resists sun damage.
Some marine grade fabrics like Sunbrella are warrantied for 5+ years against fading.
Water-resistant fabric coatings prevent mold growth.
Match new fabric patterns/colors to existing patio furniture for a cohesive look.

Thoroughly restoring sagging patio chairs with new cushions, strengthened frames, and refreshed covers revives the furniture so it looks and functions like new again. The repairs should last for many more years of use.

Preventing Patio Chair Sagging

While some sagging over time is inevitable, you can prolong the life and comfort of your patio chairs by taking preventative measures. Practicing proper maintenance, storage, and choosing high quality materials to begin with reduces wear and tear so your outdoor furniture stays structurally sound.

Regular Maintenance

Making patio chair care a part of your regular routine helps nip sagging issues in the bud before they escalate into bigger problems.

Inspect Hardware and Joints

Periodically check for loose bolts, nuts, and screws at joints. Tighten any that are loose.
Look for wobbly armrests or rocking legs that indicate loose connectors. Reinforce with brackets.
Sand and touch up paint on metal frames to prevent rust corrosion that weakens integrity.

Check/Replace Straps and Webbing

Examine plastic/fabric strapping for stretching, cracking, brittleness, or tearing.
Swap out worn straps for new outdoor-rated strapping. Knot any frayed spots.

Follow Cushion Care Instructions

Read and adhere to manufacturer directions for cleaning cushions to prevent deterioration.
Routinely flip and rotate cushions to distribute wear and compression evenly.

Proper Outdoor Storage

Safeguarding chairs when not in use protects from elements that degrade materials faster.

Cover When Not in Use

Use tightly fitted waterproof covers specifically sized for your chairs.
Breathable fabric allows airflow and prevents mold. Polyethylene sheds rain.

Keep Cushions Dry and Flip Regularly

Store cushions on edge instead of flat to avoid moisture collection.
After rain or morning dew, stand cushions on end to dry out before replacing.

Avoid Direct Sun Exposure

Keep chairs and cushions out of direct sunlight when not in use to limit UV damage.
Store in a shaded area like a covered patio or invest in a protective furniture cover.

High Quality Materials

Sag-resistant patio chairs start with investing in durable, weather-tolerant construction.

Look for Rust-Resistant, Powder Coated Frames

Powder coated aluminum and galvanized steel resist chipping, peeling, and rust corrosion that weakens frames.
Wrought iron or epoxy-coated wrought iron is another durable outdoor frame option.

Choose Fade and Weather Resistant Fabrics

Acrylic, olefin, and solution-dyed polyester fabrics resist UV fading and deterioration.
Performance treatments like Sunbrella fabric offer guaranteed UV protection.

Select Dense, Sturdy Cushion Fillings

High density foam, synthetic down, and hollow fill polyfiber maintain cushion shape and support.
Inner support batting adds an extra layer so cushions rebound after compression.

With vigilant preventative maintenance and weather-tough materials, you can enjoy properly supportive patio chairs that don’t sag season after season.
