Best Soft Innerspring Mattresses


Our review process

We've already done all the heavy lifting researching soft innerspring mattresses. That way, you don't have to pour over confusing articles about selecting the right one for you. By reading this guide, you'll have an excellent understanding of what kinds of mattresses are available on the market, so you can confidently purchase a mattress that will ensure comfortable sleep for years to come.

If you're a side-sleeper, a soft innerspring mattress may be a better choice for you. Featuring firm edges, innerspring mattresses will maintain their even surface for ideal support over time. They are good at dissipating heat to help you maintain a cool body temperature. These innerspring mattresses are designed with different types of coils, so you can choose what's right for you depending on your needs. They are made with various materials, so you can choose from a range of foam densities. These breathable mattresses will provide proper ventilation and airflow, preventing any moisture build-up. However, they have poor motion isolation, making them a bad fit for light sleepers. Additionally, they sometimes make a lot of noise, potentially interrupting your sleep every time you move.

Soft mattresses are perfect for people who sleep on their sides. They have contouring support, adjusting to your body's natural curves for maximum comfort. Providing additional support, they are great for people who have back problems or joint pain. However, they provide less support than other mattresses, so you should search for a harder mattress if you have back problems. Moreover, soft mattresses can become lumpy or sag with extended use, so it's likely that they'll be less supportive and comfortable since your body won't be aligned properly.
