Our Verdict

Leesa Original

Novaform Serafina Pearl

The Novaform Serafina Pearl is more versatile than the Leesa Original. It offers decent support regardless of your weight and has a satisfactory performance for a range of back and stomach sleepers. It's also a little better for lighter side sleepers. The Leesa isn't as supportive for lighter people, but its good support for heavier people makes it a better option for back and stomach sleepers in that category. It's also a better option for hot sleepers.
