Our Verdict

Tempur-Pedic TEMPUR-Adapt

Novaform ComfortGrande Plus

You may prefer either the Tempur-Pedic TEMPUR-Adapt or the Novaform ComfortGrande Plus. The Novaform is a firmer mattress that uses better-quality foam, making it more durable. The Tempur-Pedic is a similar all-foam mattress, but it has a less responsive feel, which can make you feel stuck in place. It's also more contouring, and you might prefer it if you want a mattress that feels like a hug.
