Best Soft Memory Foam Mattresses


Our review process

No more trying to get through confusing articles and infographics to try to decide which soft memory foam mattress to get! By reading this guide, you'll have an excellent understanding of what types of mattresses are available on the market, so you can confidently purchase a mattress that will ensure comfortable sleep for years to come.

Before deciding on your next soft memory foam mattress, there are important things you'll want to know about. Providing pressure-point relief, these mattresses will soothe any tension in your joints. Featuring various foams, they offer the right amount of cushion. However, they can smell a bit like chemicals initially, sometimes lasting up to a couple of weeks before wearing off. Another drawback is that they aren't waterproof, so any interaction with moisture can cause degeneration and decrease their usable life.

Soft mattresses give you extra support, helping to alleviate any back problems or joint pain. They are built with a 19-21 pound indentation load deflection rating and are suitable for people who sleep on their sides. These contouring support mattresses adjust to your body for enhanced comfort. However, they may be problematic if different people will be sleeping in the bed, causing the surface to sink if there is a drastic weight difference. Moreover, the surface will become softer over time, so you'll have to replace them more often.

The Sizes Available for Soft Memory Foam Mattresses

If you like having lots of room in your bed, you will want to look at a king-size mattress. King-size mattresses are perfect for couples, offering plenty of space for you to move around. They are great for master bedrooms and measure 76" X 80". However, they are not suitable for areas with limited room, making small rooms look somewhat cluttered. Another drawback is that they are heavy and large, making them difficult to transport and flip.

Trying to find a good full-size mattress? This comfortable soft memory foam mattress might be right for you. These mattresses are suitable for couples, offering a cozy fit between the two sleepers. They are suitable for studio apartments and measure 54" X 75". Something to keep in mind is that they are short in length, so they might not be a convenient option if you're 6'3" or taller. Another downside is that they have a narrow width, which makes them less than ideal for those who prefer having extra space while sleeping.

They are built to comfortably fit couples, providing enough space for two people. However, they are not suitable for areas with limited room, since they can make the area look somewhat cluttered.
