• A tape measure

    Use a flexible tape measure. Record width, depth and height in the same unit before opening any product page.

  • Your object in view

    Keep the furniture or equipment in front of you. Product names do not confirm fit. Measurements do.

  • A place to record

    Write down W / D / H before comparing. You will need all three numbers to match against the product fit range.

  • Step 1 — Define coverage

    Identify the object type — chair, sofa, dining set, air conditioner or other. This determines which product category applies.

  • Step 2 — Measure W / D / H

    Measure at the widest, deepest and highest point. Record all three numbers in the same unit before proceeding.

  • Step 3 — Compare construction

    Review material, seam type, fastening and ventilation on the individual product page — not on a category page.

  • Step 4 — Match use conditions

    Consider seasonal, year-round, high wind or appliance use. Check the product page for applicable conditions.

  • Step 5 — Confirm care & policy

    Review cleaning instructions, storage guidance and the return policy before purchasing.

  • Step 6 — Open the exact product page

    Confirm all fit, construction and use details on the specific SKU you intend to buy before adding to cart.

Avoid these common mistakes

  • Shopping by name alone: compare the full width, depth and height with the selected cover size.
  • Assuming every product has the same features: check the material, construction and fasteners on the product page.
  • Skipping use instructions: confirm how and when the cover should be used.
  • Choosing without measuring: measure your item at its widest, deepest and highest points before selecting a size.

Your buying checklist

  1. Identify the item or complete arrangement you want to cover.
  2. Record width, depth and height using the measurement guide.
  3. Compare the available sizes in the size guide and on the product page.
  4. Review material, construction and use instructions for that product.
  5. Confirm color, package contents, delivery details and the return policy before ordering.

Need help with an edge case?

My measurements fall between two sizes. Which should I choose?

Review the product page for guidance on that specific SKU. When in doubt, contact COSFLY support before purchasing.

My furniture has an irregular shape. Can I still use a standard cover?

Some products note shape compatibility on the product page. If your furniture has an unusual shape, confirm compatibility on the specific product page or contact support.

I cannot find a product that matches my measurements.

If no product fits your recorded W/D/H, do not purchase a cover that does not match. Contact COSFLY support with your measurements for guidance.

The product name matches my furniture but the dimensions do not.

Product names are not a reliable fit indicator. Always use the W/D/H fit range on the product page. If dimensions do not match, the product is not the right fit.
