8 of the Best Soft Mattresses of 2025 Tested by CNET Sleep Experts

1 month ago 19

There are a couple of great beds that you simply can’t sleep on. Or at least, you won’t sleep well if you’re a side sleeper or someone who values soft beds. I like many of these beds, but I think those who want a soft bed should avoid these mattresses because of how firm they are:

  • Avocado Green: Avocado is one of the best brands for organic beds. That said, it’s extremely firm. The only way you should buy this bed is by spending up and adding the $500 pillow top.
  • Dreamfoam Doze: Though it’s a budget bed, the Dreamfoam Doze is a firm mattress. I’d say about a medium to medium-firm. 
  • Plank Firm Luxe: As the name suggests, the Plank Firm Luxe feels like… well, a plank. It’s one of the firmest beds I’ve tested. So if you like the softer side of things, I’d stay far away from Plank beds.

":"What kind of mattress is the softest?","answer":"

How soft your mattress is depends on the materials it’s made with. The softest beds tend to have memory foam, polyurethane foam, or a blend of the two as their comfort layers. These materials offer excellent pressure relief and can be manufactured to be ultra-plush and soft. On the other hand, latex hybrid mattresses tend to be the firmest.

Generally, softer mattresses are not better for your back because they don’t provide adequate spinal support. If a bed is too soft and you sleep on your back, you can sink in at uneven points, resulting in back pain. That said, that doesn’t mean you need a truly firm mattress, just one with enough support to keep your spine aligned.

If you live with joint pain, sleeping on a softer mattress with enough pressure relief to cushion your pressure points can be better. However, it’s not a hard rule. The ideal firmness for you depends on your preferences and sleeping positions. For example, I don’t recommend soft mattresses to people who sleep on their back because they often lack the proper spinal support. Though I always recommend them for people who sleep on their side.

Generally, you do not need a softer mattress as you age. Ultrasoft mattresses allow you to sink into them, which not only can be harmful if you sleep on your back but can also become difficult to get out of, especially if it’s slow-moving memory foam. Most people opt for firmer beds as they age.
