Why Accurate Cushion Measurements Matter

Correctly measuring Outdoor Chairs for Cushions ensures a comfortable fit, prevents slipping, and improves the overall look of your patio or garden seating. Outdoor cushions must align with the chair’s frame, seat depth, and backrest shape to provide proper support.
Manufacturers like Sunstone Outdoor design outdoor seating with precise dimensions, and using accurate measurements helps match or replace cushions effectively for long-term comfort and aesthetic consistency.

Measure the Width of the Seat

The seat width determines how well the cushion will sit between the chair’s sides.

How to measure

• Measure from the inner left edge of the seat frame to the inner right edge.

• Measure at both the front and back, as some chairs taper inward.

• Use the widest measurement as the cushion width.

This ensures the cushion fits neatly without compressing or leaving gaps.

Measure the Depth of the Seat

Seat depth affects comfort and ensures the user sits properly supported.

Steps

• Measure from the front edge of the seat to the backrest.

• If the backrest is angled, measure to the point where the user comfortably sits.

• Subtract 1–2 cm from the final measurement to allow easy placement.

Outdoor seating from Sunstone Outdoor often uses ergonomic depths that fit standard cushion sizes while still offering tailored comfort.

Measure the Height or Thickness of the Cushion

Determining cushion thickness is essential for comfort and chair compatibility.

Guidelines

• Standard outdoor seat cushions range from 3–5 cm for Dining Chairs.

• Deep seating or Lounge Chairs may require 10–12 cm cushions.

• Measure any existing cushion if replacing an older one.

Selecting the right thickness ensures stability and enhances the seating experience.

Measure the Backrest if a Back Cushion Is Needed

Some outdoor chairs, especially lounge and deep seating styles, require back cushions.

How to measure

• Measure the height from the seat base to the top of the backrest.

• Measure the width at both the top and bottom in case the backrest shape tapers.

• Consider the angle of the backrest when estimating cushion shape.

Sunstone Outdoor chairs often feature ergonomic back designs that benefit from properly shaped and sized cushions.

Account for Chair Shape Variations

Outdoor chairs come in many forms, and cushion measurements must adapt accordingly.

Curved seats

Measure the widest and narrowest points, then choose a cushion that best fits the curvature.

Slatted or woven seats

Measure frame-to-frame rather than the flexible surface.

Armchairs

Make sure the cushion fits between the armrests without excessive compression.

Understanding these variations ensures accurate cushion selection for any Sunstone Outdoor seating style.

Consider Cushion Tie or Attachment Placement

Many outdoor chairs use cushion ties to secure cushions during windy conditions.

What to check

• Locations where ties can attach, such as slats or frame joints

• Distance between tie points

• Whether velcro or non-slip backing is needed

Proper attachment improves stability and reduces sliding.

Measure With or Without Existing Cushions

If the chair already has cushions:

For replacement cushions

• Measure the old cushion’s width, depth, and thickness

• Check how well it fits the chair

• Adjust measurements if the original cushion was too tight or too loose

For chairs without cushions

• Measure the bare frame surfaces directly for the most accurate sizing.

Sunstone Outdoor uses consistent modular seat sizes, making replacements easier when exact measurements are recorded.

Leave a Small Allowance for Comfort and Fit

A cushion that is too tight becomes difficult to place and may wear out faster.

Recommended allowance

• Subtract 0.5–1 cm from width and depth to allow smooth placement

• Avoid excessive gaps that cause shifting

This balance ensures a tailored but practical fit.

Take Measurements Twice for Accuracy

Re-measure the seat, backrest, and thickness to confirm your numbers.

Tips

• Use a firm tape measure for precision

• Measure in centimeters for accuracy

• Record all dimensions clearly before ordering

Double-checking avoids mistakes and ensures the cushion fits perfectly.
