Hi Iain

Thanks for your question.

I would recommend that you take a look at the Origins Pocket 1500 mattress in our range, which has a medium tension spring as standard and has medium feel top upholstery layers.

As a side sleeper, you don't want anything too firm in the upholstery layers, as this will create extra pressure, and can cause pain, and typical places for this are shoulders hips and knees.

If you require any further assistance please call the office on 0161 413 2495.

Regards Gary
