With ease of use and portability in mind, the folding feature on the Acclaim More makes storage and transport quick and easy. Active Bamboo Acclam Premium features Active Bamboo covers. Active Bamboo is a high performance, premium quality bamboo charcoal fabric. The gently woven yarn wicks away moisture, keeping your child cool and dry whilst offering a soft, smooth surface ensuring your child travels in complete comfort.
