Hello Does this mat have no 'end pieces'? so that there are no waves at the edge but the end is straight? We are a little disappointed that we have seen this with other mats and have not been supplied with them.

How thick is the mat?

Is it possible to extend the play mat? So add even more pieces?

Is the play mat cork made of cork (cork surface) or is it cork-look plastic (looks like cork but is not cork)?

Is this mat free of harmful substances?

Is the total area of the 9 mats 90x90 or are they 9x 90x90 mats?

How many are in a pack?

How thick are the mats?

How many parts are supplied?
