In the description, is can be seen filling and add. But it is so little capacity there that removing not come for us in question. One would have definitely still buy capacity. But as I would want to have the same though, that possibly becomes difficult and also more expensive again. It is, as the pad is delivered, quasi despite the pad directly on the mattress. In addition, it kinda smells funny. But that was after one to two days aired fine. The edge is sewn so that there is a margin of about one cm, which I also do not like. Due to the given weight of the capacity to find the right pillow I find very difficult. Better I would find when a height would be indicated. This cushion I would tap under 10 cm (when the head is not it of course), I do not have, however measured. The delivery arrived quickly.
Since I have already been threatened because of a poor rating to take legal action and claims for damages, here to point out that I hurt with the rating not someone who still want someone discredit and are exclusively about my personal experiences and my personal opinion.
