Custom Pool Cushions: Waterproof, Fast-Drying and Chlorine-Resistant
A poolside cushion has it harder than any other outdoor cushion. It gets wet every day, is exposed to full-strength UV radiation, comes into contact with chlorine, and gets covered in sunscreen on top of it all. That's exactly why standard cushions from DIY stores fail fastest here – after one season they're discoloured, mouldy or flattened. In this guide we show what a genuine pool cushion has to withstand, which fabric and thickness actually work by the pool, and which measuring points matter for pool daybeds and sun loungers.
What sets pool cushions apart from ordinary outdoor cushions
A garden lounge on the patio might get properly wet twice a season. A pool cushion experiences that every day. Anyone stepping out of the water and sitting down on the lounger brings water with them. Anyone applying sunscreen and lying down transfers oil onto the fabric. Anyone who has just chlorinated the pool spreads chlorine residue with their feet. On top of that, UV radiation hits at full intensity, because pool areas are rarely shaded.
Three factors are therefore permanently elevated by the pool: moisture, chemical exposure and UV. Standard outdoor cushions usually aren't built for that. They're designed for covered patios or gardens that get a chance to dry out in between. A pool cushion has to be a level better on all three counts.
That comes down to three technical properties: the cover fabric must be made from a material that's chemically stable – meaning it doesn't react to chlorine or oily sunscreen. The foam must dry quickly and not retain water. And the workmanship must be such that seams and zips still hold up after seasons in a damp environment.
Olefin by the pool: why material properties matter here
Lulu-Belle uses 100% olefin as the cover fabric on all its cushions. By the pool, the difference from classic polyester fabrics really shows. Olefin is naturally water-repellent, UV-stable and chemically resistant – these properties come from the material itself, not from a chemical impregnation that washes out after 2–3 seasons.
In concrete terms for the pool: chlorinated water doesn't attack olefin. Sunscreen doesn't leave a permanent stain if it's wiped off within the first few days. UV radiation doesn't fade the colours as quickly as it does with polyester. And water beads off instead of soaking into the fabric.
Olefin properties that matter most by the pool:
- Water-repellent by nature – chlorinated and salt water bead off
- Chemically resistant – sunscreen, care products and chlorine don't react with the fibre
- UV-stable – barely any fading even in direct sun by the pool
- Mould-resistant – olefin provides no breeding ground for mould
- Fast-drying – the fibre doesn't retain water, the surface dries within minutes
For pool cushions we recommend the premium olefin quality, because its slightly denser weave performs even better by the pool. Anyone unsure can order free fabric samples and drip water on them before ordering – the effect is instantly visible.
Foam and drying: the real pool issue
The fabric is the visible side of a pool cushion. The foam is the invisible worry. If water gets into the foam through a poorly sealed seam or through repeated use while wet, it becomes damp. If it stays damp, it develops mould on the inside. You can't see mould from the outside – but it makes a cushion unusable after 1–2 seasons.
Lulu-Belle uses PUR foam in mattress quality. It's open-cell, so it absorbs air but doesn't retain water permanently. That means: if moisture does get in, it dries back out relatively quickly once the cushion is stood up. With denser foams (e.g. inferior PE variants in DIY-store products), water stays trapped – the cushion stays damp inside for weeks.
Practical tip: no matter how good the foam is – water shouldn't get in in the first place. The most effective pool care routine is therefore: after every pool session, **stand the cushion upright** so water can run off the outside instead of seeping into the padding. A two-minute habit that adds years to its lifespan.
| Foam type | Water absorption | Pool suitability |
|---|---|---|
| Open-cell PUR (Lulu-Belle standard) | Dries quickly | Very good |
| PE foam (DIY store) | Retains moisture | Limited |
| Closed-cell foam (premium) | Absorbs almost no water | Optional for float/pool daybeds with permanent water contact |
Which thickness for which pool use
By the pool, people lie down for longer than on a garden bench. Hours of sunbathing, reading, dozing – that's typical pool use. A cushion that's too thin starts to feel uncomfortable after 30 minutes, while one that's too thick becomes heavy if it needs to be put away after every session.
Recommendation by pool furniture type:
- Classic pool sun lounger: 8 cm thickness, the proven sweet spot for lying down for several hours
- Pool daybed (140×200 cm and larger): 10–12 cm, since longer and deeper lounging is typical
- Lounge island or XXL daybed by the pool: 12 cm – but keep in mind that the cushion will then weigh 15–20 kg and shouldn't be put away every day
- Wellness lounger without an adjustable backrest: 6–8 cm is enough for occasional use
Two Lulu-Belle models are particularly well suited to pool and daybed cushions: the Marocco outdoor mattress, with its mattress-like firmness, is the robust choice for the pool – available up to 14 cm thick. The Miami lounger cushion is the more elegant option for classic wooden loungers by the pool. Which size makes sense for which daybed is explained in detail in the complete size table from 90×200 to 200×200.
Pool furniture and its typical dimensions
Pool furniture comes in a surprisingly wide range. From narrow sun lounger sets to generous pool daybeds with a canopy – here are the most common formats we see in orders.
| Pool furniture type | Typical length | Typical width | Recommended thickness |
|---|---|---|---|
| Classic pool sun lounger | 190–200 cm | 60–75 cm | 8 cm |
| Premium pool lounger (teak/aluminium) | 200 cm | 80–95 cm | 8–10 cm |
| Single pool daybed | 200 cm | 100–120 cm | 10 cm |
| Double pool daybed | 200 cm | 140–160 cm | 10–12 cm |
| Bali-style pool daybed with canopy | 200 cm | 140–180 cm | 12 cm |
| XXL lounge island by the pool | 200–220 cm | 180–200 cm | 12 cm |
| Pool bar seat cushion | 120–200 cm | 40–50 cm | 6–8 cm |
If you want to fit out a classic pool sun lounger, you'll find the step-by-step measuring guide in Custom sun lounger cushions: how to take the right measurements. For pool daybeds there's a dedicated guide at Daybed cushions for outdoor sleeping comfort.
Seven measuring and buying mistakes with pool cushions
We see a few mistakes with pool cushions again and again. The following seven are the most common – and all of them avoidable with a bit of preparation.
- Measuring the frame instead of the lying surface. Pool loungers often have raised edges or a backrest section. You measure the inner lying surface, not the outer frame.
- Choosing a thickness that's too conservative. By the pool, people lie down longer than on a bench. 6 cm feels like a hard mattress after an hour. 8 cm is the minimum, 10 cm the comfort sweet spot.
- Ordering standard fabric for heavily used pool areas. With daily pool use, premium olefin is worth it – the lifespan increases by years, and the extra cost is manageable.
- Choosing a light colour despite intense sun exposure. Light colours are pleasant because they heat up less. But: sunscreen stains show up far more clearly on white and light grey than on sand or light beige. Medium tones are often the better pool choice.
- Not standing the cushion up after a pool session. Water then doesn't drain off but seeps in at seams and zips. A two-minute habit for years of extra lifespan.
- Storing it overnight in a damp plastic box. Sounds protective, but it's actually a mould risk. If the cushion got wet during the day, leave it open overnight rather than shutting it away.
- Rushing the cushion inside during a short spell of rain. Wet cushions need air. Better to stand it upright outside than lay it wet in the garage.
Care by the pool: chlorine, sunscreen, sand
Pool cushions don't need special treatment – but they do need consistency. The three most common pool stresses can be handled with simple routines.
Chlorine
Chlorinated water doesn't attack olefin. Still: if chlorinated water dries on the cushion, salt residue is left behind, which can stress the fabric over the long term under UV radiation. Routine: once a week, wipe the cushion down with clear water and a damp cloth. That's all it takes.
Sunscreen
Sunscreen is pool cushion killer number one – but only if you leave it to sit too long. Fresh sunscreen stains can be removed with a damp cloth and a little mild washing-up liquid. Dried-in stains take more effort. Routine: wipe the cushion down after every pool session in which sunscreen was used.
Sand and dirt
Anyone with a beach-style pool or garden knows the problem. Lulu-Belle cushions can simply be shaken off or rinsed with a garden hose – the water-repellent olefin fibre is robust enough. Important afterwards: let it dry upright, don't put it away wet.
A more detailed care guide with all the tips on cleaning, stain treatment and winter storage can be found in the care guide How to care for outdoor cushions properly – so they last forever.
Pool lounge setup: what you actually need
A perfectly set-up pool area is more than just a cushion. Three components make the difference between "a pool with loungers" and "a pool lounge you want to stay at all day."
1. The lying surface
Whether sun lounger, daybed or lounge island – that's the foundation. Recommendation: one wide, high-quality lounger is better than two narrow ones. On a 140×200 cm Marocco cushion, you can read books, doze off together, and still have room for a side tray.
2. Bolster cushions
A Milano bolster cushion turns a pool lounger into a proper reading spot. Ordered in the same fabric as the main cushion, it creates a coherent set. Our recommendation for the pool: two bolster cushions, one at the head end, one at the foot end.
3. A side tray or small table
Book, drink, phone, sunscreen – everything needs a place. A flat side tray or a small pool table is enough. It also stops drinks from being spilled on the cushion.
If you want to expand the pool area into a lounge zone (seating by the pool for guests), you'll find tips on combining seat cushions, back cushions and outdoor pillows in the guide Lounge furniture cushions: the complete guide.

Frequently asked questions about custom pool cushions
Does olefin permanently withstand chlorinated water?
Yes. Olefin doesn't react chemically with chlorine. Salt residue left behind after drying can simply be wiped off with clear water. That makes olefin one of the few fibres genuinely suited to a pool environment.
What thickness for a pool sun lounger?
At least 8 cm, because you lie down longer by the pool than on a bench. If you spend several hours a day on the lounger, you'll benefit from 10 cm.
How do I clean sunscreen stains out of a pool cushion?
Wipe fresh stains with a damp cloth and a little mild washing-up liquid. Dried-in stains need a bit more scrubbing, but can usually still be removed. Important: let it dry thoroughly after cleaning.
Can I leave the pool cushion outside permanently?
In summer, yes, as long as you stand it upright after every pool session so water can drain off. In winter it should be stored dry – garage, basement or garden shed.
Which colour works well by the pool?
Medium tones like sand, light beige or mid-grey are practical by the pool: they heat up less than anthracite, show sunscreen stains less clearly than pure white, and look good next to water.
What does a custom pool cushion cost?
The Marocco outdoor mattress starts at €137 for standard configurations. A typical pool daybed cushion in 140×200 cm with 10 cm thickness in premium fabric costs more – the exact price is calculated by the configurator depending on size and fabric choice.
How long does delivery take in the height of summer?
In July and August, production time can increase to 3–4 weeks. If you want your pool area ready in time for peak season, it's best to order in spring.
Conclusion
Pool cushions are the most demanding discipline in the outdoor category – water, UV, chlorine and sunscreen hit the fabric every single day. Investing in a custom cushion made from 100% olefin and mattress-quality PUR foam gets you a piece of furniture that withstands these conditions for many seasons, instead of needing to be replaced after one summer.
If you want to set up your pool area properly, combine a Marocco outdoor mattress with two Milano bolster cushions and stand the cushion up to dry after every pool session. That's really all it takes.
