Faq's

How do I know whether a 78 x 72-inch mattress will fit my bed?

Take the length and width of your bed frame instead of just using the advertised size. Then compare those numbers to the size and add the thickness of the mattress you want.

Should I choose a firm or extra-firm mattress?

Pick the firmness that feels right for you, your weight and how you sleep. A medium-firm mattress gives you both cushion and support while an extra-firm mattress feels harder.

What is the difference between a GRID mattress and a hybrid mattress?

GRID mattresses use SmartGRID with foam whereas the hybrid mattress mixes SmartGRID foam with individual springs. The hybrid may bounce differently so look at how each's built and how firm it feels before making a choice.

Do air channels mean a mattress will always stay cool?

No air channels help air move but they do not guarantee that the mattress will stay cool.
