Care

How do I wash my SJUMO bedding?

Silky Smooth  

  • Wash at 40°C with a mild detergent, without bleach. 60°C is also possible.
  • Air drying is the most sustainable option, but a short, low-heat tumble dry setting works too. Good to know: it dries in no time.
  • No need to iron (and not suitable for it either).

TENCEL™ Sateen

  • Wash at 30°C with a mild detergent, without bleach.
  • Turn inside out and wash with soft items only.
  • Air drying is both the most sustainable and the gentlest for the fabric. TENCEL™ naturally dries quickly.
  • Iron, if needed, on the inside only, using a low temperature.
  • Note: TENCEL™ is a 100% natural and delicate material. This gives it its exceptional softness, but also makes it more prone to creasing and friction than our Silky Smooth fabric. The subtle natural sheen may fade slightly with time.
Which detergent should I use?

Use a liquid, mild detergent without chlorine or (oxygen) bleach to protect the fabric and its colours.

Can I iron my SJUMO bedding?

Silky Smooth
Ironing is neither necessary nor possible. This collection is designed to remain wrinkle-free after washing, allowing you to enjoy a perfectly made bed right away.

Tencel™ Sateen
Ironing is possible, though often not needed. The natural TENCEL™ fibres and sateen weave help reduce wrinkles. If you prefer an ultra-sleek finish, a light iron on low heat on the inside only, works well.

Can I tumble dry my SJUMO bedding?

Silky Smooth
Air drying is the most sustainable option, but a short, low-heat tumble dry setting works too. Good to know: it dries in no time.

TENCEL™ Sateen
Air drying is both the most sustainable and the gentlest for the fabric. TENCEL naturally dries quickly.

How long does SJUMO bedding last?

With proper care, our bedding will last for years, retaining its vibrant colours even after frequent washing.

How often should I wash my bedding?

A clean bed is the ultimate comfort! We recommend washing your bedding at least once a week. Tip: For an extra fresh feeling, consider ordering additional pillowcases so you can swap them more frequently without washing the entire bedding set.

How often should I wash my pillowcases?

It’s important to wash your pillowcases regularly, at least once a week. Tip: Replace your pillowcases without washing your entire bedding set by ordering extra pillowcases for fresh nights anytime!
