The Nighthawk is a premium "pocket on pocket" spring mattress which means there are two levels of pocket spring mattresses. You only have to feel the weight of the Nighthawk mattress and you will know the quality.
The advantage of a pocket on pocket design is that you are getting 3 different feel sensations from the mattress (instead of 2 in a normal mattress). This mattress is excellent for couples with a notable difference in body weights.
It features a 5 zone pocket spring unit to meet your needs for comfort and a good night sleep without disturbance.
