Dear , I'm looking for an mattress protector with a smooth surface. The surface of the material must be smooth so that the users/partners can slide on this bed sheet. The sheets (without elastic of, for example, 220 x 200 cm) and fitted sheets (160 x 200, 180 x 200 cm bedsize) will be used by consumers who want to do a slippery Nuru Gel or Oil massage in their own bedroom. After the massage the sheet goes directly into the washing machine! So it is in principe the sheets are not meant for sleeping but as protection of the mattress during the mentioned very wet massages! The intention is that the Nuru Gel stay on both bodies and therefore not being absorbed in any way by the bed sheet! For you information the Nuru Gel is very smooth and thick in structure and is used for a body-to-body massage. If we can find the right product then we sell through our webshops and Amazon EU and US If you want I can send you some small pieces of the Polyurethane bed sheet material I have here to see what I mean and to test with the Nuru Gel which I will send too.
