Replacing Day Bed Cushions and Covers

Bed Kingdom guide · Updated October 2026 · 3 min read

If your day bed cushions have become worn, stained or simply no longer match your décor, targeted day bed cushion replacement lets you refresh the look and comfort without replacing the entire frame. Many owners find that new cushions and covers, chosen to the correct UK sizes, can transform a tired day bed into a smart, inviting piece again.

Why Day Bed Cushions Wear Out and When to Replace Them

Day beds receive heavy use as both seating and occasional sleeping space. Seat and back cushions flatten, fabric pills or fades, and piping can fray. Replace when foam no longer springs back, covers cannot be cleaned effectively, or the colour no longer suits the room. A practical checklist: sit on each cushion for 30 seconds – if it stays compressed, it needs renewal. Check seams and zips; if they split, new covers alone may not be enough.

Measuring for Correct Cushion Replacement

Accurate measurements prevent expensive mistakes. Use a tape measure to record length, width and thickness of each existing cushion in centimetres. Most UK day beds use seat cushions around 120x50cm or 135x50cm for small double or double widths, with back cushions typically 40-50cm high. Note that EU sizes differ from standard UK sizes such as small single 75x190cm (2ft6), single 90x190cm (3ft), small double 120x190cm (4ft), double 135x190cm (4ft6), king 150x200cm (5ft) and super king 180x200cm (6ft). Write down thickness. Always measure twice and record the orientation (seat versus back).

Choosing Replacement Cushion Fillings and Firmness

Foam, fibre or feather fillings each behave differently. High-density foam offers longest life for day beds used daily; fibre is softer but needs regular plumping. Decide firmness by use: firmer for seating, medium for lounging. Decision rule: if the day bed also serves as an occasional bed, choose a filling that compresses to no more than half its depth under body weight. Check product pages for exact specifications as these vary by model.

Fabric Covers – Practical Choices and Fire Safety

UK upholstered furniture and mattresses must meet the Furniture and Furnishings (Fire) (Safety) Regulations 1988; replacement covers should comply with BS 7177 where applicable. Chenille, velvet, linen and cotton are popular. Chenille hides wear well and is family-friendly. For a quick update consider washable covers with zips. Match texture and colour to existing curtains or duvet covers and sets. If your day bed has a trundle, ensure replacement cushions for the pull-out section match the main seat depth exactly.

Where to Buy Replacement Cushions and Covers

Specialist retailers and online soft-furnishing shops stock standard and made-to-measure options. At Bed Kingdom you can browse complementary items in the soft furnishings section. For complete day bed refreshes, the day beds range includes models that demonstrate current cushion styles. Consider pairing new cushions with matching throws from the new soft furnishings collection at New Soft Furnishings. If you decide a full replacement is better, the next day beds section offers fast delivery options.

Refreshing Your Existing Day Bed on a Budget

Beyond full cushion replacement, simple steps can extend life. Rotate cushions weekly, vacuum weekly with an upholstery attachment, and use fabric protector spray on clean covers. For a new look without sewing, add a fitted cushion cover over the old one. If the frame is sound but the look dated, a fresh coat of paint on wooden elements plus new cushions can modernise the piece. Always follow the maximum mattress depth stated by the bed maker if your day bed has a top bunk option; UK bunk beds must meet BS EN 747 with the guard rail rising at least 16cm above the mattress surface, and top bunks are not recommended for children under 6.

Day Bed Cushion Replacement Checklist

  • Measure every cushion: length, width, depth in cm
  • Photograph the current fabric and note colour references
  • Decide on foam density or fibre fill based on daily use
  • Choose fire-safe, washable or spot-clean fabrics
  • Order at least one spare cover for quick changes
  • Test sit for comfort before finalising
  • Check trundle section measurements separately if fitted

Following this list avoids common errors such as ordering the wrong thickness or non-matching fabric.

Frequently asked questions

Can I use standard pillow inserts for day bed cushion replacement?

Standard pillows are usually too soft and the wrong shape. Day bed cushions need firmer foam or high-loft fibre cut to precise dimensions. Measure your existing cushions and order custom or ready-made replacements that match the exact length, width and depth for proper support and neat appearance.

How do I know if my day bed uses UK or EU sizing?

UK single mattresses are 90x190cm (3ft) while EU singles are often 90x200cm. Check the frame label or measure the base exactly. Day bed cushions must fit the seating area, not the sleeping mattress size. If the frame was bought in the UK it is almost always built to UK sizes such as 135x190cm for a double.

Are replacement covers available separately from the cushion inserts?

Yes. Many suppliers sell zip-on covers alone so you can keep existing foam if it is still supportive. Look for covers with at least 5cm overlap on all sides and matching fastening style. This is the most economical way to refresh colour or pattern without buying new foam.

What fire safety rules apply to replacement day bed cushions?

All upholstered furniture and mattresses sold in the UK must comply with the Furniture and Furnishings (Fire) (Safety) Regulations 1988. Replacement covers and fillings should carry the appropriate labels. When buying, confirm the product meets BS 7177 for mattresses or equivalent for cushions to remain legally compliant.

Can replacement cushions improve the sleeping comfort of a day bed?

Yes. Upgrading from flattened fibre to high-density foam or a combination filling can add support. Choose a medium-firm filling for dual seating and sleeping use. Pair with a suitable single or small double mattress from the next-day range if the day bed has a trundle.
