Without the right mattress, narrow spaces can feel unusable if space cannot be properly ultilised.

Reasons to ditch springs

We’re experts when it comes to small narrow mattresses, so we’re always asked what’s best, new age memory foam, or traditional springs? Given the huge advances achieved with foam technology over the past decade, it’s no surprise that we’d always pick a memory foam narrow mattress. Sprung mattresses can lose up to 16% of their support in the 1st year alone, not to mention that each spring pushes back into your body with equal force meaning pressure points are inevitable. A quality memory foam mattress on the other hand distributes body weight evenly and reduces pressure by up to 80%. Memory foam also offers no motion transfer or partner roll together helping you get a better nights sleep. When it comes to custom sizes for your small narrow mattress, memory foam wins again, with springs becoming somewhat problematic. You can’t have half a spring, so the size of your mattress has to be made in increments based on the size of each spring – not to mention that the added complexity results in higher production costs. Memory foam on the other hand can be cut to any size, and a simpler production process gives better value for money.

Wait 5-6 hours and your mattress will be ready for the perfect night’s sleep.
