The Leesa Original Foam 10" Mattress is right in that sweet spot between soft and firm. It's got a balanced feel that works for a variety of sleepers.

The mattress is made up of three foam layers: a breathable top layer to help keep you cool, a memory foam middle layer for pressure relief, and a dense core support base. This combo is particularly good for side sleepers but also offers decent support for back and stomach sleepers.

According to our research, it suits different body types and sleep styles quite well, with most folks saying it feels medium-firm, around 5 to 7 on the firmness scale. This balance makes it a popular choice for back and side sleepers who need both contouring and support without that sinking feeling.

If you weigh over 230 pounds, though, you might want something a bit firmer or maybe a hybrid mattress for better support. The mattress does have a breathable top layer for cooling, but some people mentioned it can get warm over time. This can depend on your body heat and how you sleep.

Also, there's an off-gassing smell when you first unbox it, but that goes away after a few days. One thing that's pretty great is its motion isolation. If you share the bed, you're less likely to wake each other up with movements.

Pros:

  • Great support with good pressure relief, especially for side sleepers.

  • Effective motion isolation, which is perfect if you share a bed.

  • Comes with a 100-night trial, so returns are easy.

Cons:

  • Some people find it can sleep hot over longer periods.

  • Edge support might not be enough if you sit or sleep right at the edge a lot.

  • There are reports that it softens over time, which could affect long-term support and firmness.

So, the Leesa Original Foam 10" Mattress gives you a nice mix of comfort and support and comes with a generous return policy. Just keep an eye out for the potential issues with heat retention and edge support if those are important to you.
