Which Size Should I Choose?
If you sleep alone, choose a Single or Small Double. If you are buying for a couple, look at Double or King. For extra space and a more luxurious feel, King or Super King is usually the best choice.
Sleep alone
Single is compact and practical. Small Double gives more movement space without taking over the room.
Buying for a couple
Double works for smaller rooms, while King is the preferred upgrade for everyday comfort.
Want extra room
King and Super King provide a more spacious sleep area, ideal for premium comfort and minimal disturbance.
Measuring access before delivery
Check the route from your front door to the bedroom before choosing larger sizes.
Larger bed sizes, tall headboards and ottoman bases may need more turning space during delivery. Measuring access early helps avoid delivery problems.
Access checklist
- Doorways: measure width and height, including trims
- Hallways: check narrow points and tight corners
- Stairs: measure around handrails and newel posts
- Landings: check ceiling height and turning space
- Lifts: confirm internal size and that the lift is working
- Bedroom route: make sure the room is clear before delivery
If access is tight
If your hallway, stairs or landing are tight, contact us before ordering. We can help advise whether the size and style you want is suitable.
For detailed guidance on tall headboards, split headboards, bases, storage and mattresses, use the Bed Buying Guide.
