The simple answer is, the more the better! An entry-level mattress will have between 800 to 1,000 individually pocketed springs. While this provides a great night’s sleep and plenty of support, the greater the number of springs, the more diffused any movement becomes. That cuts down on the transference of those little movements during the night. So if your partner is a ‘wriggler’, a higher number of pocket springs in the centre of your mattress will make sure you’re not disturbed by their movement.Mid-range 2000 pocket-sprung mattresses are so-called because they have around 1,400 - 2,000 pocketed springs, while more complex designs will have between 2,000 – 3,000 pocketed springs of various sizes and in different designs. Some may even have an additional layer as part of a mattress topper.
