Silentnight Hadleigh 800 Pocket Memory Mattress Reviews

The Silentnight Hadleigh 800 Pocket Memory Mattress is made in the UK and comes with 5 year guarantee.

The mattress has a layer of 816 pocket springs (inside the king size). Every spring is contained in its own unique pocket as part of the revolutionary Mirapocket support system. This ensures that your weight is distributed equally over the entire mattress, with edge-to-edge springs providing the most sleeping area possible.

With the body-molding memory foam layer that is built into the mattress, you’ll experience the highest level of comfort and support possible. This layer responds to your natural shape to relieve pressure while maintaining support and movement.

The Silentnight Hadleigh 800 Pocket Memory Mattress is 25.5cm (11 inches) deep and is rated as having “medium” comfort grade. It has the following layers inside:

  • Soft quilted fabric cover, for a smooth sleep surface.
  • A layer of “body hugging” memory foam (2cm deep), that conforms to the contours of your body for additional comfort and a restful night’s sleep.
  • Followed by a layer of 816 individual pocket springs, the mattress offers zonal support, which helps to improve spinal alignment as you sleep. Your body’s weight and movements are independently responded to by each spring, resulting in an even weight distribution. Additionally, this minimises “roll together” between sleeping partners.
  • On the bottom, there is a protective layer, which distributes pressure from each spring over the entire surface area of the mattress, increasing its lifespan. 

Keep in mind that the number of springs will vary according to the size you buy. For example the single size has 465 pocket springs, the small double has 589, the double has 682, king size has 816, and lastly the super king size has 960 pocket springs.
