How to choose the right super king mattress
When choosing the right super king mattress, there are a few things to consider:
- The size of your room. Super king mattresses are the biggest standard size available – they measure 180 x 200 cm. So you need to make sure you have enough space for it.
- The firmness. Our super king mattresses are available in 4 different feels – soft, medium, medium-firm and firm. You can also browse our mattresses by firmness.
- The depth. The EASE® mattress is made in 3 depths: 20cm. 22cm and 25cm. The Pro® SmartCool™ is 21 cm deep, the Pro® Plus SmartCool™ is 25 cm, and the Pro® Luxe SmartCool™ is 30 cm. Typically, the deeper a mattress, the more support it provides.
Super king mattresses: FAQs
Is a super king the largest mattress size?
A super king mattress is the largest standard size available in the UK, measuring 180 x 200 cm. However, at TEMPUR®, we also offer the non-standard emperor mattress, which measures 200 x 200 cm.
Is a super king mattress the same size as two singles?
No, a super king mattress is not the same size as two standard singles pushed together. A super king size mattress measures 180 x 200 cm, while two single mattresses together measure 180 x 190 cm. However, two long single mattresses would fit side-by-side as they have a slightly smaller width.
Who would benefit from a super king size mattress?
A super king mattress is perfect for couples who want a little extra sleep space. As the largest standard UK size, it’s one of the biggest options you can choose from. They’re also ideal for tall people, as they provide a little extra length than other mattresses.
