The Bottom LinePurple offers superior cost-based value than Intellibed. The cooling, pressure-relief, and durability expectancy for both mattresses is comparable. Intellibed is bit more supportive and has better conforming ability. Both have flexible sleep surfaces and adapt to different body structures cozily. However, the Intellibed is far more pricier than Purple. Purple is better at isolating motion and hence, more suitable for bed sharing.
