1000 Pocket Springs - Why Pocket Springs?
Since pocket springs work independently from each other, pocket sprung mattresses support your body weight to a greater degree than an open coil spring system (also known as standard sprung). This body-reactive design can help you to feel comfortable and well-supported as you sleep, offering even pressure distribution to reduce the risk of pressure point build-up.
Why Memory Foam?
Memory foam layers provide comfort and support to your shoulders, back and hips, and works in harmony with your body to ensure that you are sleeping in the correct anatomical position, meaning you can wake feeling refreshed and free of any minor aches and pains.
Memory foam also offers relief for your pressure points which encourages healthy blood circulation, as well as reducing the need to toss and turn during the night, meaning a deeper and more restful sleep.
Density/Comfort Rating - What's Best For You?
Each type of mattress varies by comfort grade, from soft to firm. Our density ratings (provided by the manufacturer) are to be used as a guide. Every comfort grade has its advantages, and the right one for you depends on your personal preferences but also your favoured sleeping position.
The SleepSoul Harmony Mattress is rated as Medium
| Soft | Offers the least resistance, providing a gentle support base, contouring to your natural body shape. Perfect for side sleepers. |
| Medium | Gentle support system, conforming to the shape of your body. Great if you sleep on your side or front. |
| Firm | Provides essential support to maintain natural spinal alignment. Ideal for back or front sleepers. |

What you're paying
The struck-through figure is what this piece sells for at other UK retailers — not a former price of ours. How our pricing works.
