Layer Details
- Cover. A graphite cool cover with graphene, which means heat is drawn away from your body rather than trapped at the surface. Hot sleepers should notice the difference most.
- Gel layer. StaycoolTM Gel provides body-sensitive pressure relief while keeping the sleep surface cool. It cushions shoulders and hips without the warmth some foams build up.
- Support layer. A high-density support layer sits beneath the gel, adding structure. This is where much of the firm, supportive feel comes from.
- Springs. Pocket springs at the base move independently, so your partner's tossing is less likely to disturb you. The king size uses 1,000 springs; other sizes aren't detailed.

- Leaves room for everything else: At 90cm wide, the UK single leaves space in a child's bedroom for a desk, wardrobe and toy storage, and we suggest at least 2.1m x 2.8m of floor.
- Cooler nights for warm teenagers: The graphite cover with graphene draws heat away from the body, which means a teenager who kicks off the duvet should wake a little less clammy.
- Firm support for a growing frame: A high-density support layer over pocket springs gives solid pushback, which back and stomach sleepers tend to find keeps them level rather than sinking.
- Two beds in a guest room: Two UK singles let a spare room sleep two friends or siblings separately, with the firm feel suiting most adult guests who dislike soft beds.
- Suits allergy-prone sleepers: The mattress is hypoallergenic, which helps a child or guest who wakes stuffy from dust or allergens.
This size suits you if...
You're buying for a child or teenager who sleeps warm and prefers a firm bed, you're furnishing a small spare room or study that needs to stay usable by day, or you sleep alone in a first flat and want cooling support without giving up the floor.
Consider another size if...
You're over six foot, or you share the bed with a partner or regularly with a child. We'd recommend the UK double instead; allow at least 2.6m x 2.8m for the UK double.

Will the SmartTemp Ortho UK single fit a mid sleeper or cabin bed?
The 90 x 190cm footprint matches a standard UK single frame, but the mattress is 25cm deep. Raised frames such as bunks, cabin beds and mid sleepers often set a maximum mattress depth so the safety rail stays high enough. Check the frame maker's guidance before buying, because a mattress that is too deep can make the top rail unsafe.
Is the SmartTemp Ortho UK single too firm for a child?
It may be for a light child who sleeps on their side. This is a firm mattress, and lighter bodies may not sink in enough for shoulders and hips to settle comfortably. Children and teens who sleep on their back or front, or who are heavier, are more likely to get on well with it.
How much floor space does a SmartTemp Ortho UK single need?
We suggest allowing at least 2.1m x 2.8m for a UK single, which leaves space to walk round the bed and open a wardrobe. If you're fitting two UK singles for siblings or guests, measure for both beds and a walkway between them before you order.
Is a UK single SmartTemp Ortho long enough for an adult?
The UK single is 190cm long, the same length as the UK double. Most adults fit, but taller sleepers may find their feet near the end. The UK king is 10cm longer, although it's a much wider bed. We suggest at least 2.7m x 2.9m of floor space for the UK king.
Should I choose a UK single or UK double SmartTemp Ortho for a spare room?
A UK single keeps a spare room that doubles as an office usable, needing at least 2.1m x 2.8m by our guidance. The UK double is 45cm wider and gives 67.5cm each for two sharing, so pick the UK double if couples stay over. We suggest at least 2.6m x 2.8m for the UK double.
