Seasonal is a 25 cm connected-spring mattress with a layer of natural cotton among its layers.

The cotton makes a difference to airflow. It draws off moisture and keeps the mattress cooler, which you notice in summer.

It flips, and the feel is steady and even, like all connected-spring mattresses.

If you want the same mattress taller, Seasonal Extra at 30 cm. And if two of you share the bed and one moves, this will not isolate the movement.
