Pros & Cons

Q1. Who would you recommend a Allswell Supreme Cooling Mattress to?


  • It’s a good choice for side sleepers who need pressure relief.
  • The mattress provides a balance of comfort and firmness.
  • Suitable for hot sleepers.

Q2. Who should avoid Allswell Supreme Cooling Mattresses?


  • Not suitable for people who prefer extra firmness
  • It may not be a budget-friendly option.


I often wondered why I feel sometimes like I’m sleeping on the floor and sometimes like on a cloud. Later, I discovered that it was all because of the concept of mattress firmness!

Mattress firmness only describes how supportive a mattress is. It refers to the materials utilized in it. This involves the way they are stacked inside the mattress. Your sleep quality is greatly impacted by this. Let us have a look at some of the impacts:

  • Spine Alignment: Back discomfort might result from your spine sagging. This occurs due to soft mattress. On the other hand, a firm mattress won’t support your curves. It can strain your pressure spots. Hence, achieving the good firmness is important. It guarantees your spinal neutrality.
  • Pressure Relief: Lower back, hips, and shoulders often experience a little pressure from a comfortable mattress. Particularly for side sleepers, softer mattresses typically relieve pressure points. Although firmer mattresses may not relieve pressure points. They can give good support in general.
  • Mobility and Comfort: You can move around easily while you sleep on a mattress. If this is the case then that is the right firmness for you. Soft mattresses might cause you to feel trapped. Extremely firm mattresses can limit your range of motion.

On the basis of your choice, you can choose the suitable firmness.

In this mattress review, let us discuss the firmness of Allswell Supreme Cooling Mattress.
