Is the SureCool actually cooling?

The gel-infused foam helps a little compared with basic memory foam, but it is still an all-foam bed. Hot sleepers should expect it to sleep warmer than a hybrid with coils and breathable covers.

Which firmness should I choose?

Side sleepers usually do best with plush or medium, back sleepers with medium, and stomach or heavier sleepers with firm. The soft options sink more, so pick firm if you dislike that hug.

Does it need a box spring?

No. It works on a platform bed, slatted frame, box spring or adjustable base. A solid, supportive base matters more than the type.

How long does it take to expand?

Most of the expansion happens within a few hours, and the mattress reaches full height in about 24 to 48 hours. The new-foam smell usually fades in a few days with the room aired out.

Is it good for couples?

It absorbs motion well, so a partner's movement is less noticeable. The trade-off is weak edge support and a deep sink that some find hard to roll out of.

How does it compare with a hybrid mattress?

It costs less and gives a deeper foam hug, but hybrids with coils offer better edge support, easier movement and more airflow. Choose this one if you want maximum sink-in comfort.
