Your second consideration should be support and comfort for your weight and build. Good and proper support is determined by the coil springs inside the mattress and should be conducive to proper spine alignment. You must be able to try out the beds by lying on them for at least 10 minutes, getting a feel of how firm the mattress is. When you lying sideways, your spine should be straight and when you lie on your back, your spine should maintain its natural curve. Do as Goldilocks did and choose a mattress that is not too hard, not too soft but just right and according to orthopedic experts, that should mean the firmest and most supportive mattress you feel comfortable in. Try your usual sleeping positions as well as a few tosses and turns. If it is going to be a bed for two, you should go for something larger and one that minimizes partner disturbance and should enable you to lie side-by-side, with your arms behind your head and elbows out but not touching.
First of all you need to know why you want a new bed to begin with. Is it for a health issue? Are you looking to replace the entire bed or just the mattress? Whatever your reasons are, remember that it is best to consider your purchase as a whole and not as individual components since the mattress and the base work together. When choosing a bed due to issues with back pain, it is all the most important that you prioritize support as the bed you buy must be able to adjust to your body shape and support your correct posture. Depending on the severity of your back problem, you may need to use those memory foam mattresses that are so popular nowadays because they actually conform to your body shape and give you the proper support you need.
