A mattress is a surface used for sleeping. Mattresses typically consist of layering different materials and spring units, although foam can also be used.
Standard Mattress Sizes (UK) :
- Small Single 75cm x 190cm / 2’6″ x 6’3″
- Single 90cm x 190cm / 3′ x 6’3″
- Small Double 120cm x 190cm / 4′ x 6’3″
- Double 135cm x 190cm / 4’6 x 6’3″
- King Size 150cm x 200cm / 5′ x 6’6″
- Super King 180cm x 200cm / 6′ x 6’6″
Spring Units:
Open Coil – open coil (also known as Miracoil, Continuous Coil, Standard Coil, Bonnel Coil and Box Spring) are the most common types of mattresses, consisting of an interconnected spring system. Coils are measured in gauges which indicate the thickness of the wire used for the springs. The lower the number, the ticker the spring, which typically results in a firmer mattress. For this reason, many orthopaedic mattresses use an open coil structure.
Pocket Spring – Pocket sprung mattresses are made of a formation of springs that are housed in individual pockets, allowing them to work independently of each other. Pocket sprung mattresses offer high quality support.
Foam – Foam mattresses, including memory and reflex foam, use a different structure modified from visco-elastic polyurethane, foam mattresses provide a different feel.
Fillings:
Most mattresses consist of a combination of spring units and fillings. A range of materials can be used to fill a mattress, which help determine the overall quality of the product.
Borders:
All mattresses have a bordered edge to retain its structure.
Rod Edge – A rod edge is a type of structural edging found around both the top and bottom of the mattress, holding the structure in place. It is used most commonly on open coil structures for frame support, and prevents the mattress from tipping and losing shape.
Side Stitching – Some mattress borders are stitched on the sides for additional support and to prevent sagging. These can be machine stitched, although hand side stitching is a skilled and traditional technique still used on top quality mattresses.
Foam Encapsulated – Foam encapsulated borders are used as an alternative to rod edges, foam encapsulated sides are more commonly used on pocket sprung mattresses.
Styles & Finishes:
Pillowtop – A pillowtop mattress has an extra layer of padding or cushioning attached to the top to increase comfort. Pillowtop mattresses can help back pain by providing a softer sleeping surface.
Quilted – Quilting produces a smoother and flatter surface when compared with other finishes. This method is mostly used, but not limited to, open coil mattresses.
Handles – Handles are stitched to the sides of mattresses for ease of turning, and are often seen on higher-quality mattresses.
Vents – Vents are a sign of a quality mattress, embedded n the sides to promote airflow to reduce moisture and heat build-up.
