Assessed from Komfi's product page, captured September 2026, and from regular price comparison across our UK retail partners.
Price is the main draw here. Starting from £112.32 and topping out at £154, the Unity Comfort costs less than many rolled mattresses, which makes it a reasonable option if you're furnishing a spare room or working to a tight budget. The size range covers smaller frames well, with Small Single and Small Double options alongside the standard Single, Double and King. The boxed format also means delivery is straightforward rather than a two-person struggle. That said, its layer construction and firmness aren't published, so treat this as a budget-first choice rather than one picked on specification.

Who's it NOT for?
If you want detailed reassurance about materials, firmness or support before spending, this model may frustrate you, as full specifications aren't confirmed in our data. Larger sizes are also limited: there's no Super King option, so couples wanting maximum space will need to look elsewhere.
Komfi Unity Comfort Mattress in a Box
How much does the Komfi Unity Comfort mattress cost?
Prices range from £112 to £154 depending on the size you choose, with the cheapest option starting from £112.32. That places it firmly at the budget end of the mattress market.
What sizes does the Komfi Unity Comfort come in?
It's available in five UK sizes: Small Single, Single, Small Double, Double and King. There's no Super King option, which is a slight limitation for couples who want extra width.
Is the Komfi Unity Comfort a bed in a box mattress?
Yes. It arrives rolled and vacuum-packed in a box, which makes it easier to get through doorways and up narrow staircases than a traditional flat-delivered mattress.
