The Mainstays 8 in Pocket Spring Hybrid is a bed-in-a-box mattress that pairs a quilted cover and 1 inch of support foam with 7 inches of individually wrapped pocket coils. It is a medium-firm mattress, so it leans toward support rather than plush cushioning. The pocket coils are meant to cut motion transfer, which helps if you share the bed. At 8 inches it is a thin mattress, so it suits guest rooms, kids' rooms and tight budgets more than shoppers who want a deep, pillow-top feel.

This Mainstays King mattress is an 8 in hybrid with a medium-firm feel. It ships compressed and rolled in a box, which makes setup easier to manage.
It has a soft quilted cover over 1 in of support foam and 7 in of individually wrapped pocket coils. The design combines cushioning with steady support.
The pocketed coils help minimize motion transfer, so movement on one side is less likely to disturb the other. The medium-firm feel suits back, side, and stomach sleepers.
