5. Care and maintenance

After purchasing your ideal Suilong 20cm Hybrid Mattress, proper maintenance and care is key to ensuring that your mattress remains comfortable and supportive over time. Here are some useful maintenance tips:

  • Rotate regularly

To evenly distribute signs of use and extend the life of your mattress, it is recommended that you rotate your mattress every three to six months. This is especially important for mattresses that are used on both sides.

  • Keep it clean

Regular cleaning of your mattress will prevent dust and allergens from building up. Dust and fine particles can be removed by gently cleaning the surface with a hoover, and stains can be gently wiped away with a mild detergent and a damp cloth.

  • Use a mattress protector

A good mattress protector not only protects the mattress from stains and liquids, but also adds an extra layer of comfort. Make sure you choose a breathable material to keep your mattress airy and dry.

  • Avoid jumping

As tempting as it sounds, jumping on your mattress can damage its internal structure, reducing its support and longevity.

  • Air circulation

Ensure that your mattress is in an environment with good air circulation, which helps to prevent moisture build-up and mould growth. It's a good habit to open windows regularly for ventilation.

By following these simple but effective maintenance and care tips, your Suilong 20cm Hybrid Mattress will be able to provide you with optimum comfort and support for a long time.
