Topper HR is a mattress made of HR foam. The firmness level of the mattress is H2 and the height is 5 centimetres. The HR topper is light and comfortable because the HR foam has an irregular structure and high porosity. HR foam has excellent ventilation, which ensures a high level of hygiene during sleep. HR foam returns to its original shape twice as quickly, supporting the spine when it changes position during sleep. The mattress has hypoallergenic properties. The anti-allergenic quilted cover does not absorb allergens, which is an advantage for allergy sufferers. The cover can also be washed in the washing machine at 40 degrees Celsius, which makes it easier to maintain sleep hygiene. The cover has a zip so that it can be easily removed and put on.
