Why This Comparison Matters
When you want more room to sleep freely without disturbing your partner, two options come up: Super King and Two Singles. Both offer generous width — but their benefits differ depending on comfort, room layout and budget.
UK Sizes Compared (Mattress Dimensions)
| Option | Size (cm) | Space per sleeper | Best for |
|---|---|---|---|
| Super King | 180 × 200 | Shared | Couples who want luxury space |
| Two Singles | 90 × 190 each / 180 × 190 total | Individual | Couples with different sleep needs |
Note: Frame sizing can be slightly wider due to headboards and side rails.

2) Super King — Cons

3) Two Singles — Pros
- Individual comfort: each mattress can suit different needs
- Easy transport upstairs (especially tight staircases)
- Can be separated when needed (guest flexibility)
4) Two Singles — Cons
- “Middle gap” — needs a wide fitted sheet, topper or zip-link

Storage bed options more limited
Access & Delivery Considerations

Who Should Choose What?
| You should choose... | If... |
|---|---|
| Super King | You both sleep lightly and love open space |
| Two Singles | One/both need different firmness levels |
| Two Singles | Tight or awkward access to upstairs rooms |
| Super King | You want the premium, unified look |
Final Recommendation
If access allows and both sleepers share similar comfort needs — go Super King.
If you want custom comfort for each person — choose Two Singles and get a zip-link mattress for the best of both worlds.
