After measuring your mattress, we advise you to add 2 cm to the measured height for safety.
Among the ranges offered, we invite you to choose the next highest one.
Example: If your mattress is 21 cm thick (19 cm + 2 cm safety margin), we recommend choosing a cover with a thickness closest to 21 cm (available thicknesses vary depending on the range). For the Noxaalon® , choose a 27 cm cover, and for the Texaal® , choose a 28 cm cover. For the length and width, simply choose the dimensions of your mattress.
If your mattress cover seems a little too big, don't worry: it won't affect its protective effectiveness. The important thing is that the mattress is completely covered to isolate you from dust mite allergens.
Information – Texaal® Cotton: To account for the natural shrinkage of cotton, an extra margin is added during the manufacturing of anti-mites (1.5% to 6% depending on the fabric batch). Upon receipt, these covers will be larger than the ordered size; they will reach their final size after a few washes.
