Summer sheets with freshness, design and 100% cotton for your bedroom

Happyfriday summer sheets are designed to turn your bedroom into a fresh retreat full of personality during the hot months. Made in Spain from 100% cotton, each piece combines exclusive digital printing with breathable fabrics that help regulate temperature on the warmest nights of the year.
 
From watercolour and floral prints to geometric and minimalist designs, our collection includes sheets in every bed size: from 90 to 180 cm. Each design is unique and created by our design team in Spain. If you're not sure where to start, find out how to choose summer sheets with our complete guide.
 

 

Types of summer sheets

Not all sheets are the same. Fabric is the factor that most affects how they feel on your skin in summer. At Happyfriday we work with the most valued finishes in the textile industry. 150 or 200 thread count? Discover the differences between 150 and 200 threads to choose wisely.
 


100% cotton percale sheets

Percale is the most popular fabric for summer. It's 100% cotton with a plain weave that gives it a crisp, fresh texture to the touch, like a freshly ironed shirt. Percale softens with use.
 
Its fabric density of between 150 and 200 threads ensures excellent breathability. Air circulates between the threads and body heat escapes easily, making it the go-to fabric for warm nights. At Happyfriday our percale sheets have a maximum of 200 threads, the perfect balance between freshness and softness.


100% cotton sheets

The whole Happyfriday collection is made from 100% cotton. Cotton is the most recommended material for the hot months because it absorbs moisture, helps regulate temperature and feels soft and pleasant on the skin. It stands up well to washing.


Summer sheets to suit your decorating style 

Your bedroom is where you start and end every day. At Happyfriday we design collections to suit different looks and personalities. Looking for inspiration? See our ideas for dressing the bed in summer with seasonal colours and prints.

The star colours are dusty pink, sage green, sky blue and off-white. Perfect for Provençal, boho or Mediterranean-style bedrooms.
 

Minimalist and Nordic style

For those who prefer a clean, functional bedroom, our collections of geometric lines and colour blocks are the perfect choice. Fine stripes, subtle checks and symmetrical compositions in reduced palettes of two or three colours. White, grey and earthy tones dominate. Find out more about summer bedroom decor trends.

Materials that look after your rest

100% cotton, the most refreshing fabric

Cotton is the natural fibre par excellence and remains the go-to material for summer bedding. Its hollow tubular structure acts as a natural temperature-regulating system: it absorbs body moisture, carries it to the surface of the fabric and lets it evaporate, keeping a continuous feeling of freshness on the skin. 
Cotton stands up well to washing.
 

Made in Spain

Happyfriday designs all its bedding in Cocentaina (Alicante) and prints and makes it in workshops in Spain.

How we work

Every print is created in our studio in Cocentaina (Alicante) and printed and made in workshops in Spain. Digital printing works like a large-format printer: it applies the ink directly onto the fabric. That's why it allows prints with many colours, gradients and fine details. All our textiles are certified OEKO-TEX® STANDARD 100 Class I: AITEX, an independent laboratory, tests them for substances harmful to health.

How to care for my sheets in summer

Follow these washing instructions to keep their colour and feel for longer. Read our full guide on how to wash your summer sheets to get the most out of your bedding.
 
• Machine wash at 40 degrees maximum
• Use a neutral liquid detergent. Don't use bleach or too much fabric softener, which reduces the breathability of cotton.
• Always separate whites from colours, especially in the first washes.
• Do not dry clean; tumble dry on a short cycle and do not soak.
• Iron at medium temperature (120–150 degrees) with the fabric slightly damp.
• Store in a dry, ventilated place away from direct light. Rotate between two or three sets to spread the wear.




What are summer sheets and how do they differ from winter ones?

Summer sheets are made from light, highly breathable fabrics designed to keep you cool in the warmer months. Their more open weaves allow better air circulation and help heat and moisture escape, unlike winter fabrics such as flannel, which hold in body heat.


What is thread count (TC) and what number is best for summer?

TC indicates how many threads there are in the fabric, adding weft and warp. The higher the TC, the denser and softer the fabric. For summer, the ideal range is between 150 and 200 TC: dense enough for softness, but open enough to let air circulate.


What size sheet do I need for my bed?

The sheet adds between 80 and 120 cm to the width of your bed, leaving 30–45 cm of overhang on each side. For a 150 cm bed, a 240x270 cm flat sheet is the ideal size. See our sheet size guide for a complete reference by bed size.


How many sets of sheets do I need for summer?

We recommend at least three sets in rotation: one on the bed, one clean in the cupboard and one being washed or dried. In summer, with the heat and more sweating, it's common to wash sheets every 5–7 days, so three sets mean you always have clean bedding. With children at home, or if you tend to sweat at night, four sets give you extra peace of mind.


Can summer sheets also be used in spring and autumn?

Yes. 100% cotton sheets aren't just for summer: their temperature-regulating ability makes them comfortable all year round in most climates in Spain. In spring and autumn they work perfectly as in-between-season sheets, especially in areas with mild temperatures.


How do I wash summer sheets properly?

To wash summer sheets properly, use a normal machine programme at a maximum of 40 °C and a neutral liquid detergent. Avoid bleach and too much fabric softener to better preserve the fibres and softness of the fabric. Whenever possible, dry the sheets outdoors. Read all the details in our guide on how to wash your summer sheets.


Why is cotton better than microfibre for summer?

Cotton has a natural structure that helps regulate temperature and lets the skin breathe. It absorbs moisture, carries it to the surface and helps it evaporate, creating a continuous feeling of freshness. Synthetic fabrics, on the other hand, can trap moisture on the surface and feel stickier and hotter. Cotton also doesn't build up static.


What's the difference between a fitted sheet and a flat sheet?

The fitted sheet covers the mattress and is held in place with elastic. The flat sheet covers the body and protects the comforter from direct contact with the skin; in summer it can also be used on its own as the only cover. More details in our guide to the difference between fitted and flat sheets.


Do Happyfriday sheets shrink in the wash?

All 100% cotton sheets can have some natural residual shrinkage in the first washes. At Happyfriday we compensate for this shrinkage during manufacturing, so our sheets keep their nominal sizes once stabilised. To minimise it, wash at a maximum of 40 °C for the first few uses and air dry instead of tumble drying. High-temperature drying is the main cause of excessive shrinkage in cotton fabrics.
