Our Verdict

Novaform Legacy

SweetNight CoolNest Pro

The Novaform Legacy and the SweetNight CoolNest Pro are both good options, but they're each best-suited to different types of sleepers. The Novaform is more supportive, making it a better choice for back and stomach sleepers, while the SweetNight provides more pressure relief, making it a better choice for side sleepers. Both options do an excellent job of dissipating motion, which can help couples sleep more peacefully. The Novaform is more responsive, making it easier to move around on, but the SweetNight is more cooling, so it's a better choice if you often wake up overheated.
