How to Measure Replacement Cushions for Deep Seating Furniture

If your outdoor cushions are worn out or flattened, replacing them can make your furniture look brand new. The most accurate way to measure replacement cushions for deep seating furniture is to measure the inside of the furniture frame, not the old cushions.

Because cushions change shape over time, measuring the frame helps ensure your new replacement cushions fit beautifully and comfortably.

Important: Always remove the old cushions before measuring. This gives you a much more accurate starting point for ordering custom replacement cushions or standard-size outdoor cushions.

What You’ll Need

• A tape measure
• A notepad or phone to record measurements
• Your furniture frame

If your measurements are unusual or do not match a standard size, you may want to explore custom outdoor replacement cushions for the best fit.

Step 1: Measure the Inside Width of the Seat Frame

The seat width is the distance from the inside left arm to the inside right arm of the chair, loveseat, or sofa.

1. Remove the seat cushion.
2. Place your tape measure on the inside edge of one arm.
3. Measure straight across to the inside edge of the opposite arm.

Example: 24 inches wide.

If you are measuring a single chair, you may also want to browse chair replacement cushions, deep seating chair replacement cushions, or custom chair cushion sets.

Step 2: Measure the Inside Depth of the Seat Frame

The seat depth is the distance from the front inside edge of the frame to the inside back of the frame.

1. Place the tape measure at the front inside edge of the seat frame.
2. Measure straight back to the inside back of the chair frame.

Example: 26 inches deep.

Correct depth measurements are especially important when ordering wicker furniture replacement cushions and outdoor wicker replacement cushions.

Step 3: Choose the Cushion Thickness (Height)

Cushion thickness refers to how thick the seat cushion will be from top to bottom.

Most deep seating outdoor furniture uses cushions that are:

• 4–5 inches thick for standard seating
• 5–6 inches thick for extra comfort

Example: 5 inches thick.

If you are replacing cushions on a full seating group, you can also compare sizes across replacement sofa cushions and wicker sofa cushions.

Step 4: Measure the Back Cushion Area

For deep seating furniture, you also need to measure the back cushion area.

1. Measure the inside width between the arms.
2. Measure the back height from the seat base to the top of the frame.

Example: 24 inches wide × 20 inches high.

Measuring both the seat and back area helps you choose the right deep seating replacement cushions for chairs, loveseats, and sofas.

Taking a few extra minutes to measure carefully can help you order the right replacement cushions the first time. If your furniture is from a premium brand, you may also want to explore Lane Venture replacement cushions and other brand-specific cushion options.

Frequently Asked Questions

Should I measure the old cushions or the furniture frame?

Always measure the inside of the furniture frame. Old outdoor cushions can flatten, stretch, or lose shape over time, which makes them less accurate than the frame itself.

What if I need custom-size replacement cushions?

If your furniture has unusual dimensions, shop custom replacement cushions for a made-to-order fit.

What thickness should deep seating cushions be?

Most deep seating replacement cushions are between 4 and 6 inches thick, depending on the look and comfort level you want.
