We purchased a king size Octasmart Deluxe Memory Foam Mattress last month, and to be honest we are wishing that we had purchased one of these years ago.
Extremely comfortable mattress, and a great nights sleep, the pillows are also fantastic, both offer great support, just a well made value for money product, that has transformed our sleeping patterns, I would seriously recommend this product for anyone that is experiencing a troubled sleep on their existing mattress.
