Is the Origins Pocket Reflex 1000 suitable for side sleepers?

Hello. We are currently looking for a new mattress. I have a chronic back pain condition and my wife has intermittent shoulder pain. I weigh around 14 stone and my OH is around 10 stone. We are both side sleepers and in our 50s. Unfortunately, we do have a budget . Would the Origins Pocket Reflex 1000 (double) be suitable?

Kind regards

Tony
