There are 5 criteria you should look for when searching for a quality mattress: Materials used, support, pressure relief, resilience, and breath-ability.
When choosing a bed be sure to research the brand and find out what materials are used. Are they quality materials? Are they safe, organic, and eco-friendly? Using cheap materials means the mattress will not hold up over time and it will start to sink in. Do not buy a mattress that does not disclose what materials are used, and where the materials are sourced from. A high-quality material that is also eco-friendly is latex.
If you suffer from mid or lower back pain, or are a back sleeper then pay extra attention. You need a responsive and supportive material that pushes up into the lumbar spine and allows the low back to de-stress. This allows the muscles to relax and gives your discs and other joints time to decompress throughout the night. In my opinion, latex mattresses offer the best support.
3. Pressure Relief
If you suffer from shoulder or hip pain, or are a side sleeper then pressure relief is very important for you. Pressure relief is necessary for the parts of your body that stick out (shoulders and hips). Taking pressure off these areas will allow those ball and socket joints the relief from the constant stress they are under all day. Memory foam mattresses offer great pressure relief.
As humans, everything starts with our core, and this is the same with mattresses. If you want a resilient mattress that has longevity then your mattress needs a strong core. This is why hybrid mattresses have gained so much popularity over the last few years. Hybrid mattresses have a strong multi-coil core that is typically layered with several types of memory foam, latex, or other material. These new types of pocket coils allow the bed to be resilient and helps preserve the life of the mattress.
You can have a quality mattress but if it’s too dense it wont be breathable. The bed will trap heat leaving you sweaty and uncomfortable throughout the night. I sleep hot so it is important that I have a breathable mattress. Having a quality, light weight, open celled mattress will keep you cool and dry at night.
