A soft mattress can be an excellent choice for some sleepers, but an uncomfortable bed for others. If you’re a petite sleeper or a side sleeper, a soft mattress can be just what you need for a good night’s sleep. However, if you’re a back sleeper, stomach sleeper, or a heavy sleeper, you might wake up with a bad back because your soft mattress doesn’t provide the support you need. That said, there are a few soft mattresses that have extra support features, such as responsive transition layers or targeted back support. These soft yet supportive mattresses are better suited for a wide range of sleepers.
