Mattress extension compatible with the Seaside Lille+ basic mattress, measuring 68 × 130 cm, allows for expansion to 68 × 168 cm, fitting seamlessly with all other beds from the Seaside Lille+ series. Thanks to its design, dust and dirt struggle to settle into the mattress. Its easily washable cover ensures a high level of hygiene, making it suitable for allergy sufferers. In case of accidents, the top part of the two-piece cover can be washed separately using the attached zip-off zipper, ensuring convenient maintenance and cleanliness.

Product Information

The mattress core is made of Oeko-Tex certified European HR cold foam, which is very comfortable, breathable, and hypoallergenic, easily recovers its shape after use and has a high carrying capacity. Volume weight 28.5-33 kg/m3.
The cover is made of GOTS-certified organic herringbone cotton, quilted with a layer of Oeko-Tex certified recycled PET fibres.
The removable cover is machine washable (max. 40°).
The mattress is manufactured in Europe and complies with European safety standards and norms. The mattress is tested according to the safety standard EN 16890 and in compliance with the European fire safety standards EN 71-2 and BS 7177.
