Custom 3-Part Sun Lounger Cushion Covers – Full-Length Comfort, Built in Three Smart Sections

When you’re lying back to soak up the sun, the last thing you want is a cushion that bunches, slides, or folds awkwardly. And if your lounger folds into three segments — for the back, seat, and leg rest — then you know: finding a cushion cover that fits properly is next to impossible off the shelf.

That’s exactly why we make 3-part sun lounger cushion covers to order, shaped around your lounger’s exact frame, dimensions, and movement.

So whether you’re upgrading your patio, decking out your yacht, or refreshing your holiday rental — this is the cover that’ll do the job properly.


Three Sections, One Seamless Fit

Split-frame loungers are great for adjusting to the perfect position — but only if the cushion can keep up. A poorly fitted pad will fold in the wrong place, wrinkle at the hinge, or slide down when you recline.

That’s why we tailor your cushion cover in three parts, carefully measured and constructed with clean joins, flexible hinges (where needed), and the right amount of give. The result? A cushion that bends where it should, stays in place, and looks sharp from every angle.


Choose a Style That Matches the Setting

Comfort is key — but style matters too. That’s why we offer a range of design options to suit your space, whether you’re poolside, on deck, or relaxing in the garden:

  • Wrap Style – smooth, fitted, and minimal

  • Box Style – sharp corners and clean lines

  • Box with Piping – a tailored finish with classic detail

  • Box Pleat Style – adds structure and a more traditional feel

Every cushion cover is made to order in the UK, using upholstery-grade materials and stitched with care by professionals who know their way around a sun lounger.


Fabric Options That Work Hard So You Don’t Have To

Outdoor cushions need more than good looks — they need to take a beating from the elements and still hold up. That’s why we offer a full range of indoor/outdoor fabrics to suit your space:

  • For outdoor and marine use, opt for UV-stable, water-resistant, mildew-proof fabrics that can handle sun, spray and spills

  • For shaded patios or indoor loungers, choose from soft-touch velvets, breathable cottons, or classic woven blends

Want versatility? Go reversible — choose a different fabric on each side and flip your cushion to match your mood or the season.

Not sure what to pick? We’ll send you free fabric samples so you can compare in person.


Need Foam Inserts Too? We’ll Cut All Three Parts to Match

Old foam can flatten fast — especially with three-panel loungers that see a lot of action. If you’re starting fresh or replacing worn-out pads, we’ll cut custom foam inserts for each section of your lounger.

Options include:

  • High-density foam – firm and supportive, ideal for upright or structured loungers

  • Reflex foam – softer, springier, and better for all-day lounging

To top it off, we offer Dacron or Stockinette wrapping to smooth the fit and give the cushion a plump, full shape.


Smart Extras That Make Life Easy

You don’t just want it to look good — it has to work. That’s why we include a range of practical features to keep your 3-part sun lounger cushion functional:

  • Choose your zip position for easy removal and refitting

  • Add a non-slip base to prevent sliding on metal or wood frames

  • Include Velcro tabs, ties, or fasteners to hold each section securely in place

And yes — all covers are removable and washable, so you can keep them looking sharp season after season.


Refresh What Works – No Need to Replace It All

There’s no need to buy a whole new lounger just because the cushion’s seen better days. With our custom-made covers and foam options, you can bring your sunbed back to life — for a fraction of the cost.

It’s more sustainable, more affordable, and a lot more satisfying than making do with a sagging or ill-fitting cushion.


How to Order Your 3-Part Sun Lounger Cushion Cover

We’ve made it easy — no guessing, no fiddling. Just follow these steps:

  1. Choose your units — mm, cm or inches

  2. Enter the length, width, and thickness for each of the three sections

  3. Pick your style, fabric, and any add-ons

  4. Add special instructions — like where the hinges are, zip position, or tie locations

  5. Click “Add to Cart” — and let us do the rest
