Did you know that a significant proportion of the human population is a side sleeper? Resting on your side means that you should take care to find the correct mattresses for this position. There are certain mattresses best suited for side sleepers. If you have been picking your mattresses randomly without considering your sleeping position, it is time you rethink this.

Many side sleepers opt for a softer mattress because the shoulders and knees are cushioned, necessary for proper alignment. Heavier people, though, may choose a firmer mattress that will not change shape with pressure. Another important factor is the product quality, as some mattresses for side sleepers provide more cushioning and better support than others. The right mattress will provide pressure relief and optimal spinal alignment for you, no matter your body weight.

Choosing a great mattress is not a straightforward task. That is why we compiled our choices for the best mattress for side sleepers in the UK listed below to help you decide. If you are a side sleeper, it will benefit you to go through this review to know the appropriate mattresses available for you.
