Which is better for side sleepers?

The Avenco. Its medium-firm feel cushions shoulders and hips more than the Zinus firm feel, which some side sleepers find too hard.

Which is better for back and stomach sleepers?

The Zinus. A firm surface keeps the spine straighter for back and stomach sleepers, and its cooling top helps hot sleepers.

Is the Zinus worth $9 more than the Avenco?

For most shoppers, yes. You get a stated 10-year warranty and a 4.3 rating from 7,396 buyers instead of 3.5 from 12, for about $9 more.

Do both need a box spring?

No. Both are hybrids with pocket coils and work on a platform bed or slatted frame. The Zinus listing says a box spring is not required.

Neither maker publishes a lifespan figure. The Zinus states a 10-year limited warranty; the Avenco listing states no warranty term, so the Zinus gives you more recourse if it sags.

Are both good for hot sleepers?

The Zinus is the better bet. It has a cooling Airflow memory foam top aimed at hot sleepers. The Avenco is a standard memory foam hybrid with no cooling feature listed.
