Super King Size Mattress

The lucky one. The Super King Mattress (203×203cm) is just 20cms wider than a King  – it’s indulgence at its best!

Essentially as massive square shape of endless relaxation.

The Super King Mattress is reserved for those that can accommodate the width whilst maintaining balance in the room.

King Size Mattress

The King Mattress (183×203cm) is just 30cms wider than a Queen – but a whole world of difference.

The King Mattress is essentially the width of two singles, yet longer. A King is also available as a split king (two long singles) when seperate feels are required (firm, medium, plush) or partner disturbance needs to be minimised.

Consider the benefits of a King at the outset before investing in your bed frame and linen – or upgrade from a Queen when changing your bed base.

Kings are most suited to couples that have the good fortune of additional space to rest well and parents with wandering kids and morning snugglers.

Queen Size Mattress

The most popular size of all. The Queen Mattress (153×203cm) is the same length as a King and both wider and longer than a Double.

The Queen Mattress is the size you generally find on showroom floors and is often the reference point for pricing.

Look for brands that offer the quality you would expect depending on your requirements, be it your primary mattress or guest room.

Queens are most suited to couples or teenagers and adults that appreciate the additional space.

Double Size Mattress

The one for specific uses. The Double Mattress (137×190cm) is the same length as a Single, but shorter than and not as wide as a Queen.

The Double mattresses are very close in price to Queen mattresses at the entry level.

Think about whether a Queen is an option or a King Single – that is longer and provides more space in the room.

Doubles are most suited to teenagers and adults that have restricted space, are not very tall or have a double bed frame they wish to keep.

King Single Size Mattress

As the largest of singles, the King Single Mattress (107x203cm) is both wider and longer than the Single, with the equivalent length of a Queen and King.

The King Single Mattress is available as a trundle bed (with a roll out and lift bottom mattress) and converts to a great option for overnight or visiting guests.

Look for great value in brands that specialise in King Single Mattress ranges and remember that most mattress ranges are also available as a King Single if required.

King Singles are fantastic for kids and parents that enjoy the additional space for bed time reading. Also well suited to growing teenagers and individuals of all ages who appreciate the full length and additional width whilst retaining precious living space.

Long Single Size Mattress

You guessed it, it’s a Single – but longer. The Long Single Mattress (92x203cm) is the same width as a Single, but the length of a Queen and King. It’s primary reason for existence is the Split King, as two Long Singles placed side-by-side are the exact dimensions of a King Mattress.

On some occasions, Long Singles are an option for individuals requiring additional length to a Single – but space restricts the choice of the wider King Single.

Look for brands with consistent mattress height across comfort levels (firm, medium, plush) when creating a Split King to suit individual partner needs.

Long Singles are ideal for Adjustable Split King Beds (as each side moves independently) and are also popular for couples with different comfort requirements.

Single Size Mattress

True to its name, the Single Mattress (92x190cm) is ideally suited to a single individual.  It’s the most cost effective option and also provides the most available recreational space for the room. A perfect size in the right circumstance.

The Single Mattress is available as a trundle bed (with a roll out and lift bottom mattress) and converts to a great option for overnight or visiting guests.

Look for great value in brands that specialise in Single Mattress ranges and remember that most mattress ranges are also available as a single if required.

Singles are enjoyed by kids as their first bed and individuals of all ages who value the overall space in their room and are comfortable with the compact size for sleeping.
