2ft6″ x 6ft3″ (76cm x 190cm)
Best for:
• Young children transitioning from a cot.
• Smaller guest rooms or box rooms where space is limited.
Considerations:
Ideal for compact spaces, but may feel cramped for teenagers or adults.
• Teenagers and young adults.
• Solo sleepers who want just enough space.
Great for narrow rooms, but may not provide enough room for taller individuals or those who toss and turn.
• Couples who don’t mind sharing a cosy space.
• Single sleepers who like extra room to stretch out.
A practical option for smaller bedrooms, though it might feel tight for two.
• Couples in standard-sized bedrooms.
• Single sleepers wanting more comfort.
The most popular size in the UK, offering versatility. However, larger couples may prefer more space.
5ft x 6ft6″ (150cm x 200cm)
• Couples who want extra width and length.
• Taller individuals needing additional legroom.
Works well in larger bedrooms but ensure your room has enough space to move around comfortably.
6ft x 6ft6″ (180cm x 200cm)
• Couples who prioritise maximum space and luxury.
• Families where children or pets occasionally share the bed.
The ultimate in comfort, but it requires a spacious bedroom to avoid feeling cramped.
1. Small Bedrooms
• Choose a Small Double or Single to maximise space without sacrificing comfort.
2. Taller Individuals
• Opt for King or Super King for extra legroom. A mattress length of 6ft6″ (200cm) ensures no dangling feet!
3. Couples Sharing a Bed
• Consider body size and sleep habits. A Double may feel cramped for two, especially if one partner is a restless sleeper.
4. Family Sleepers
• Super King is ideal if kids or pets join you in bed occasionally.
Quick Tips
• Always measure your bedroom space before buying. Leave at least 24 inches (60cm) of walking space around the bed.
• Don’t forget bed frames! The overall size, including the frame, can add extra bulk.

This mattress comes with a free 60-night comfort trial, just like all of our mattresses.
We encourage you to sleep on your new mattress for at least 30 nights, as it can take time for your body to adjust. If, after 30 nights, it’s not feeling quite right, simply get in touch — we’ll be happy to swap it for you.
Still not in love by night 60? No worries. The comfort trial gives you the flexibility to find the perfect fit.
