Ultrabounce! That’s a joke! There’s not even a tiny bounce or any support in this bed at all. Our dog is only 9kg and sinks to the very bottom of the bed with no comfort at all-he may aswell sleep on the carpet which he is more or less doing with this bed. It’s a misleading advert and offers no comfort. Very disappointing for a silent night, was thinking of ordering one of their mattresses for humans but don’t think I fancy it now!
