Given its presence in retailer showrooms across the UK, my encounter with the Silentnight 800 Mirapocket Mattress took place in-store. As soon as I laid down, I could feel the core pocket spring technology contouring to my body - pretty ideal as a back sleeper like me usually prefers a firm mattress to maintain spinal alignment. The breathability of the Eco Comfort Fibres™ filling was a nice touch, which I presume would result in a fresher feeling throughout the night, especially for someone of my size. The 5-year guarantee is the cherry on top, almost entirely covering a mattress's typical lifespan, bringing peace of mind to heavier individuals concerned about durability.
