Both raise the head and foot independently, and the Sino Luban adds a zero-gravity position meant to spread body weight. The Irvine adds massage, which some shoppers find soothing. Neither is a medical device.

Is the Irvine worth the extra $185?

Only if you want massage and USB charging. The Sino Luban covers the core adjustable functions, plus night lighting, for less.

Which has the higher weight limit?
