4. Care and Maintenance

After purchasing a high-quality Suilong 20cm Hybrid Mattress, proper care and maintenance is essential to extend the life of your mattress and keep it comfortable. Below are some practical maintenance and care tips:

1. Turn and rotate regularly

Whilst Suilong's premium materials are designed to minimise indentation and wear and tear, rotating the mattress on a regular basis (every 3 to 6 months) can help to evenly distribute the pressure of use, thereby extending the life of the mattress. For mattresses designed for double-sided use, turning is equally important.

2. Keep it clean and dry

Keeping your mattress clean and dry is important to prevent dust mites and other allergens from building up. Regular gentle cleaning of the mattress surface with a hoover will remove dust and dead skin cells. If the mattress is soiled, you can spot clean it with a mild detergent and a damp cloth, but make sure the mattress is completely dry before using it again.

3. Use a mattress protector

Using a breathable, waterproof mattress protector is an effective way to protect your mattress from spills and stains. Covers also prevent dander and dust mites from penetrating the inside of the mattress, helping to keep it hygienic and clean.

4. Avoid jumping

Although mattresses may look sturdy, frequent jumping and heavy pressure may damage the internal structure of the mattress, affecting its support and comfort. Teaching children not to jump on the bed is an important measure to protect the mattress.

By following these simple maintenance and care guidelines, your Suilong 20cm Hybrid Mattress will be able to provide you with a long and comfortable sleep experience. Remember, good maintenance habits will not only prolong the life of your mattress, but will also ensure that you enjoy a quality night's sleep every night.
