How firm or soft should my king mattress in a box be?

Back and stomach sleepers, on the other hand, tend to prefer a firmer mattress that supports their spine and keeps them from sinking too deeply.
It's important to note that a mattress in a box may feel firmer initially due to compression during shipping, but it should soften up within a few days of being unpacked and aired out.

What are the differences between memory foam, latex, and hybrid king mattresses in a box?
Memory foam, latex, and hybrid king mattresses in a box are popular types of mattresses that offer different benefits to consumers. Memory foam mattresses are made from viscoelastic foam that conforms to the body's shape, providing pressure relief and support. They are known for their ability to isolate motion, making them a good choice for couples who have different sleep patterns.
Latex mattresses, on the other hand, are made from natural or synthetic latex and offer a firmer feel than memory foam. They are also hypoallergenic and resistant to dust mites and mold, making them a good choice for those with allergies.
Hybrid mattresses combine the features of memory foam and latex with the support of a coil system. They typically have a layer of memory foam or latex on top of a layer of pocketed coils, providing the best of both worlds in terms of support and comfort.
When choosing between these three types of mattresses, it ultimately comes down to personal preference and sleep needs.

Hybrid mattresses are a good choice for those who want a balance of support and comfort.
