Hi there -- Thanks for your question. Many people would give you a blanket response that if you have back pain, you must need a firmer mattress. Those people would be wrong. The correct answer is that unfortunately there is not enough information here to answer this question one way or another.

Back pain is generally a result of your spine not being held in proper neutral alignment while you are sleeping. This means that your spine should be in the same shape and position that it has when you are standing. In order to provide this proper alignment, a mattress has to be the right fit for YOUR particular spinal alignment needs. This will be a function of your weight, preferred sleep position(s), body shape, etc.

Having a mattress that is too firm for your particular needs can certainly cause your spine to be in a funky twisted position. For example, a curvy person sleeping on their side on a rock hard mattress would likely result in back pain. By the same token though, a mattress that is too soft — again, relative to your particular needs — can also cause back pain. An easy example here would be that a heavier stomach sleeper on a fluffy pillow top will usually wake up with back pain.

So, even if I knew what mattress you have, depending on what your particular needs are, that same mattress could be EITHER too firm for you OR too soft for you.

Net, choosing a mattress that will give you proper spinal alignment can be tricky because it is highly personal. That's a key reason why the shopping experience on GoodBed is so personalized, and why it's so important for every mattress shopper to take the GoodBed Quiz (https://www.goodbed.com/mattress-finder/), since it will assess your individual needs and help you search across brands and stores to identify options that will work for your full array or requirements.

I'm sorry we couldn't be more helpful on this one, but I hope that background information was at least somewhat useful in better understanding how to answer this question.
