Key takeaways
- Solution-dyed acrylic: Sunbrella is the most widely known brand; color is in the fiber, so fade resistance is high. Breathable and cleanable with diluted bleach for many colors. This is the most common premium choice for custom cushions.
- Solution-dyed polyester or olefin: Lower cost, quick drying, decent fade resistance. Olefin feels slicker.
- Printed polyester: Cheapest, widest pattern range; fades faster in full sun.
- Performance indoor-outdoor fabrics: Some makers offer textured weaves and boucle-style outdoor fabrics, which are comfortable but can snag on rough wicker.
Custom made cushions for outdoor furniture are worth ordering when your frames are a non-standard size or shape, when you want a specific fabric grade such as solution-dyed acrylic, or when stock cushions keep sliding, bunching or flattening; expect to pay roughly two to four times the price of off-the-shelf cushions and wait about 2 to 6 weeks for production. The process comes down to three decisions: exact measurements or a template, the foam core, and the fabric and finishing details.
Custom vs Standard: When Each Makes Sense
| Factor | Standard cushions | Custom made cushions |
|---|---|---|
| Typical price, deep seat cushion (seat + back) | $60–$150 per chair | $180–$450+ per chair |
| Lead time | In stock | About 2–6 weeks |
| Sizes | Fixed (e.g. 20 x 20, 24 x 24 in) | Any dimension, often to 1/4 or 1/2 in |
| Shapes | Squares, rectangles, a few T-shapes | Trapezoids, curves, cutouts, round, L-shapes |
| Foam | Fiberfill or basic foam | Choice of density, quick-dry, wrapped |
| Fabric | Limited, often printed polyester | Hundreds of options, solution-dyed acrylic |
| Returns | Usually easy | Often non-refundable once cut |
Custom is usually the better choice for older frames where replacement cushions are no longer made, built-in benches and window seats, sectional pieces with unusual depths, and high-use furniture where cheap cushions flatten within a season.
Measuring for Custom Cushions
The single biggest source of disappointment with custom cushions is measurement error. Take each of these:
- Width: Across the seat at the front and again at the back. Many chairs taper, often by 2 to 4 inches, which needs a trapezoid cushion.
- Depth: From the front edge of the frame to the back frame or backrest, at seat level.
- Thickness: Measure the old cushion, or decide based on how far the seat should sit above the frame. Deep seating usually uses 4 to 6 inch seats.
- Back cushion: Width at the top and bottom, plus height from seat surface to the top of the frame or desired height.
- Cutouts: Note any posts or arm supports. Measure their position from the back corner and their size.
- Curves and odd shapes: Make a paper or cardboard template, mark “top” and “front”, and either photograph it on a grid or mail it if the maker accepts templates.
Compare your measurements against the old cushion, but do not copy a sagged or shrunken cushion. Ask whether the maker adds or subtracts for fit; most expect the frame’s actual dimensions and adjust for seams themselves.
Choosing the Foam Core
| Fill | Feel | Drains water? | Typical use | Expected lifespan |
|---|---|---|---|---|
| High-density polyurethane (1.8–2.5 lb/ft³) | Firm to medium | No, unless wrapped | Covered patios, deep seating | 5–8 years |
| Polyurethane wrapped in polyester batting | Softer, rounded edges | Slowly | Lounge comfort, covered areas | 4–7 years |
| Reticulated (open-cell) quick-dry foam | Firm, springy | Yes, in minutes | Pool areas, uncovered decks, boats | 7–10 years |
| Polyester fiberfill | Plush, soft | Poorly | Back pillows, throw cushions | 2–4 years |
| Dual layer (firm core + soft top) | Supportive with a soft surface | Depends on layers | Daily-use sofas and sectionals | 6–10 years |
For uncovered furniture, quick-dry foam paired with a mesh or breathable bottom panel is the most effective combination; water passes through rather than soaking the core. For covered porches, a wrapped high-density foam feels closer to indoor furniture.
Fabric Grades and What They Mean
- Solution-dyed acrylic: Sunbrella is the most widely known brand; color is in the fiber, so fade resistance is high. Breathable and cleanable with diluted bleach for many colors. This is the most common premium choice for custom cushions.
- Solution-dyed polyester or olefin: Lower cost, quick drying, decent fade resistance. Olefin feels slicker.
- Printed polyester: Cheapest, widest pattern range; fades faster in full sun.
- Performance indoor-outdoor fabrics: Some makers offer textured weaves and boucle-style outdoor fabrics, which are comfortable but can snag on rough wicker.
Request fabric swatches before committing. Colors shift between screens and real sunlight, and the hand feel varies widely between brands.
Construction Details to Specify
- Edge style: Knife edge (two panels, thin edge) for thin pads; box edge (separate side strip) for 3 inch and thicker cushions.
- Welting or piping: Adds definition and protects seams but can trap water if the cord is not outdoor-rated.
- Zippers: Removable covers with outdoor-grade nylon or plastic zippers allow washing and foam replacement.
- Ties and straps: Specify placement to match your frame, typically at the back corners, or hook-and-loop tabs on metal frames.
- Tufting or buttons: Keeps fill from shifting; adds cost and spots where water can collect.
- Thread: UV-resistant polyester or PTFE thread outlasts standard thread, which can rot in sun within a few years.
Custom Covers for Outdoor Furniture
Custom furniture covers follow the same logic: measure the width, depth and height of the piece, including arms and any umbrella hole, and add 1 to 2 inches for ease. Look for breathable fabrics with vents to avoid trapping condensation, elastic hems or drawstrings to resist wind, and reinforced corners. Custom covers often cost $80 to $300 depending on size, versus $30 to $100 for standard ones. They are most valuable for sectionals and odd-shaped pieces that standard covers do not fit.
Ordering Checklist
- Measure every cushion position separately, even on matching chairs; frames vary by up to an inch.
- Draw a simple sketch with dimensions, front edge and tie positions.
- Order swatches and view them outdoors.
- Choose foam based on whether furniture is covered or exposed.
- Confirm lead time, shipping, return policy and warranty on fabric and foam.
- Consider ordering one cushion first if you have many chairs, to confirm the fit.
DIY or Local Upholsterer?
Online custom cushion services are usually cheapest for straightforward rectangles and trapezoids. A local upholsterer can come measure, handle curved or built-in seating, and adjust on site, but often charges more per cushion. A DIY approach using replacement foam and a sewn cover can halve the cost if you are comfortable sewing box-edge cushions with zippers; expect 3 to 6 hours per deep seat cushion for a first attempt.
