What is the Best Soft Mattress 2024?

Buying a mattress is not something that we do regularly. Since you’re here, the chances are you’re either replacing an old and worn-out mattress or buying your first. Either way, you’re likely overwhelmed by the various brands available today. But what you’ll find even more confusing are the different mattress technologies and the jargon used in the market. In this ultimate mattress buying guide, we’ve highlighted some critical tips to guide you when choosing the best mattress to buy today.

Medium-firm mattresses are the most popular primarily because they accommodate lots of people. But some beds stray more towards being either noticeably firmer or softer. We’ve created this quick guide for people who prefer softer mattresses. 

What is the Best Soft Mattress 2024?

What is a Soft Mattress?

This may sound like an obvious question, but there’s more to it. Feel, commonly known as firmness, is subjective and mainly depends on your weight, sleeping style, and personal preferences. That suggests that what one person perceives as a soft mattress may not be as soft for someone else, depending on their weight. 
Firmness in mattresses relates to the rating on the 1-10 mattress firmness scale, where one is feather soft, and 10 is rock hard. Soft mattresses are rated around 2-3. 

What Makes Soft Mattresses Soft?

Soft mattresses are characterized by a depth of between 30 and 35 centimeters. The comfort layers make up 5 to 10 centimeters of this thickness.

This thick comfort section means there’s extra cushioning filling up all the spaces that would otherwise be left between your body and the mattress. The foam material also quickly conforms to your body curves, leaving you sleeping ‘in’ the mattress. In addition to more support, this hugging feeling also eases pressure points keeping your joints happy.

Types of Soft Mattresses

Memory Foam

This is a favourite material for most people because of its comfort factor. Memory foam is known for its ability to mould to the sleeper’s body to reduce pressure and soothe aching joints. It also returns to its original shape when you wake up, a feature that significantly boosts its durability. 

Polyfoam 

Polyfoam is an inexpensive alternative to memory foam. Unlike memory foam, polyfoam mattresses are less dense and less viscous, meaning sleepers feel like they are sleeping “on” the mattress. Besides affordability, the potential benefit of polyfoam mattresses is that they sleep cooler than memory foam. 

Latex 

Latex mattresses are another major player in the sleep industry partly because they are sourced from natural materials. Latex mattresses are typically set up as memory foam competitors. But it’s important to note that latex is denser than memory foam, making it more responsive and bouncier. Go with a latex mattress if you fancy sleeping on an eco-friendly and less toxic mattress. The flipside of latex mattresses is their higher price tags though there’s an option to go synthetic. 

Hot Sleepers Beware

Soft mattresses are prone to sleeping hot because they tend to encourage excess sinking. By hugging your body, the foam may create pockets that trap heat around you, causing excessive sweating. This does not happen with all mattress brands. But if you overheat at night, it’s crucial that you consider a mattress with cooling technology, for instance, gel or PCM infusion.

Lastly, this mattress will make an incredible purchase for a guest room.
