KYMDAN mattresses come in many sizes and are usually made from single pieces of material according to standard specifications in widths of 0.8m, 0.9m, 1.0m, 1.2m, 1.4m, 1.5m, 1.6m and 1.8m. For oversized mattresses having non-standard specifications, attached pieces are connected with glue to make mattresses of specified sizes. The quality of such attachments is assured by the use of special adhesives that are produced by KYMDAN. Though extra-large mattresses are not truly comparable to those made of a single piece of material, seams are hidden by covers. Quality is still assured because KYMDAN applies the same warranty policy to extra-large mattresses as to mattresses made from a single piece of material.
KYMDAN Deluxe mattresses are designed with large square holes at the mattress base and small holes on the top surface that are evenly and widely distributed. The result is increased aeration due to increased surface contact area.
