It's essential to wait until your mattress/upholstery is completely dry before using it again. It typically takes 4-6 hours for it to dry completely. Once it's dry, you may use it as you usually do. Turning on the air conditioning system or opening windows is recommended to help with ventilation and speed up drying. This will also ensure that no moisture is trapped in the fibres, which may lead to mould or mildew build-up.
