It is a memory foam, you can check in a bed store near Ain Khaleed roundabout, I forgot the name of the store.. it is in Salwa road heading to Ain Khaleed roundabout and then you take U turn, the store then on your right hand side one of those stores on the first block. I think you can recognize its sign on the store saying memory foam.

Or you also can check latex pad in The One at Villagio.
