Many customers will ask us to explain why memory foam mattresses are almost always much thinner than the more traditional mattresses. And without doubt there is a noticeable difference in the depth when you compare both types of mattresses. So what causes the difference in thickness?

There is a simple reason for this – the spring in the likes of “pocket sprung mattresses” take up space in the centre of the mattress – up to 12 or 14 cm in depth – the spring is encased to prevent it from bursting through into the softer cushions. The actual foams and cushion within the “pocket sprung mattress” may not be much greater than 8 or 10cm in depth. However when the depth of the spring area and the foams are combined, the overall thickness is usually noticeably greater than the memory foam mattresses to which I referred earlier.

Memory foam mattresses on the other hand combine layers of foams and cushions which mold to the shape of the body. For instance the PerDormire Duet 500 (available in 3ft, 4’6”, 5’ and 6’) has 6 distinct layers. The top layer is a Stretch polycotton fabric. The next layer is Visco Mind Quilting (2cm). There is a raw cotton layer followed by Visco Mind Superior Layer (3cm) and then a thick 12cm layer of waterfoamed expanded polyurethane interior. A layer of mixed fibre lining completes the bed. So despite this myriad of layers carefully placed on top of each other, the overall thickness is still less than the sprung mattress detailed above. And now the one million euro question: which is more comfortable?

The honest answer is that it depends on the type of comfort you enjoy! And, in the next blog, I’ll go into more detail on the type of comfort and support the two types of mattresses provide. Consumers can call in to the Drumbriston Furniture outlet on the Dublin Rd, Monaghan Town for a full selection of these and more products.
