Choosing a budget single mattress UK shoppers can compare properly starts with the bed size, not the price. The All Foam Budget Mattresses range includes a standard Single Eco Mattress, but you should still measure the frame, check the 6-inch depth and decide whether its medium-firm standard foam construction suits the intended use.
A Single mattress is often chosen for smaller bedrooms, guest rooms, children's rooms and one-person sleeping spaces. Those uses can have very different requirements, so the word Single only tells you the width and length category. It does not tell you the firmness, depth, material or comfort construction.
This guide focuses specifically on buying a lower-cost UK Single without repeating the broader budget mattress advice already covered elsewhere on the All Foam site.
What size is a standard UK Single mattress?
Quick answer
The All Foam standard Single mattress size is 90 cm x 190 cm. Measure the actual bed frame before ordering because older, imported, handmade or specialist frames may not match a standard UK size exactly.
A mattress should fit the sleeping platform correctly without being forced into a smaller opening or leaving an unexpected gap around the edges.
If the bed is genuinely non-standard, a standard Single may not be the right solution.
Is a 3ft mattress the same as a UK Single?
In UK mattress shopping, 3ft is commonly used to describe the standard Single width. The All Foam Single measures 90 cm wide by 190 cm long.
Retailer terminology can vary, especially when comparing imported or European sizes, so use the stated centimetre dimensions rather than relying only on the name.
Our UK mattress sizes guide explains the standard mattress dimensions across the wider range.
Measure the frame before buying
Do not measure only the old mattress if you are unsure whether it fitted correctly.
Measure the internal sleeping area of the bed frame or the top surface of the divan base. Check both width and length. If the frame has raised side rails, measure the space the mattress actually needs to sit within.
It is also worth checking access to the room. Narrow staircases, loft rooms and tight turns can matter even with a Single mattress.
If the measurements do not match 90 cm x 190 cm, stop before ordering and investigate the actual frame size.
Why choose a budget Single instead of a larger size?
Room space is often the main reason. A Single can leave more usable floor area than a Double, which may matter in a box room, guest bedroom or compact flat.
Do not choose a Single simply because it is cheaper if the sleeper genuinely needs more width. Size should suit the room and intended sleeper before the budget is considered.
What should a budget Single mattress include?
A lower-priced Single should still provide a clear specification.
Check:
- exact 90 cm x 190 cm dimensions where standard UK Single applies
- total mattress depth
- foam type or layer construction
- stated firmness
- cover included
- whether it is one-sided or double-sided
- warranty period
- current Single price
- delivery terms
The All Foam Eco Mattress lists these points directly. It uses a 6-inch premium medium-firm foam construction, a Coolmax cover, a double-sided design and a 3-year warranty.
Is the All Foam Single Eco Mattress memory foam?
No.
The Eco Mattress is a standard foam mattress. It does not contain a separate memory foam comfort layer.
That distinction is important because customers searching for an affordable Single can easily end up comparing very different materials under the same budget label.
If you specifically want the slower, contouring response of memory foam, compare the separate premium memory foam mattress range. If your priority is a simpler lower-cost medium-firm foam construction, the Eco Mattress is the relevant All Foam budget option.
Our budget foam vs memory foam mattress guide explains the material difference in more detail.
Is a 6-inch Single mattress thick enough?
It can be, but there is no universal answer.
The Eco Mattress has a 6-inch foam depth. That gives it a lower profile than the deeper premium All Foam mattresses.
Whether that is suitable depends on the sleeper, bed base and desired feel. Body weight, sleeping position and how the bed is used can all affect the experience.
For a more detailed explanation, read is a 6-inch foam mattress thick enough?.
Do not assume that every Single mattress should have the same depth simply because the width and length are standard.
Check the bed base in a small bedroom
Compact rooms often use space-saving bed frames, older divans or slatted bases. Inspect the base before blaming the mattress for an existing support problem.
Look for:
- broken or loose slats
- excessive gaps
- bowed boards
- damaged centre support
- fixings that allow the frame to move
- raised edges that reduce the usable mattress space
A new foam mattress needs an even, supportive foundation.
Replacing the mattress without correcting a damaged base can leave you with the same underlying problem.
Medium-firm is a useful starting point
The Eco Mattress is described as medium-firm.
That can suit customers looking for a balance between very soft and very firm foam, but firmness is still subjective. A lighter sleeper may experience the same mattress differently from a heavier sleeper, and sleeping position can change how pressure is distributed.
Think about the mattress feel you already prefer rather than choosing from the word budget alone.
A Single mattress for a guest room may also need to accommodate different visitors, while a mattress for one regular sleeper can be chosen around a more specific preference.
Match the Single mattress to the room and use
A standard Single is commonly chosen where floor space matters, including guest rooms and student accommodation. The mattress specification still needs to suit the actual bed and the person using it.
For occasional visitors, our budget mattress for a guest room guide covers shared-use considerations. For university or rented rooms, the budget mattress for students guide covers accommodation rules, moving and delivery access.
This guide stays focused on choosing the Single mattress itself rather than repeating those use-case articles.
Do not buy only from the headline price
A Single is often the lowest-priced size in a mattress range, so it is commonly used for from pricing.
That makes it important to confirm that the price you are comparing actually applies to the standard 90 cm x 190 cm Single and includes the specification shown on the product page.
At the time of writing, the All Foam Single Eco Mattress starts below £100. It remains a standard foam mattress, not memory foam, and its current price should always be checked on the live Budget Mattresses page before ordering.
If you are comparing several retailers, also check delivery charges and promotion thresholds rather than assuming every advertised starting price is the final delivered total.
Double-sided design and mattress care
The Eco Mattress is designed so either main face can be used as the sleeping surface.
That means it can be turned over as well as rotated as part of normal care. This differs from layered one-sided mattresses with a designated top comfort layer.
In a small room, make sure there is enough space to handle the mattress safely when turning it. Do not try to move or flip a mattress alone if its size or weight makes that unsafe.
Our double-sided foam mattress care guide explains the practical difference between turning and rotating.
What if a standard Single does not fit?
Do not squeeze, fold or permanently compress a standard mattress to force it into a non-standard frame.
If the sleeping area genuinely has unusual dimensions, measure carefully and consider whether a made-to-measure rectangular mattress is more appropriate. All Foam has a separate custom foam mattress builder for custom rectangular sizes.
Shaped mattresses and specialist furniture can require additional information, so contact All Foam where the standard online builder does not match the project.
Budget Single mattress checklist
Before ordering, confirm:
- the frame measures 90 cm x 190 cm if you are buying a standard Single
- the base is level and supportive
- the mattress depth works with the frame and room
- the foam construction is clearly described
- the stated firmness suits your preference
- the cover is included as expected
- the design is one-sided or double-sided as stated
- the warranty applies to the exact mattress
- the current Single price is clear
- delivery access is practical
This checklist is more useful than choosing the first product labelled cheap Single mattress.

Is a budget Single suitable for a small bedroom?
A Single can save floor space compared with wider mattress sizes, but suitability depends on the room layout, sleeper and bed frame rather than price alone.
What if my bed is smaller than 90 cm x 190 cm?
Do not assume a standard Single will fit. Measure the actual sleeping area and consider a custom solution if the frame is genuinely non-standard.
Final answer
A budget single mattress UK buyer should first confirm the standard 90 cm x 190 cm frame size, then compare depth, foam type, firmness, cover, warranty and final delivered price.
The All Foam Budget Mattresses page lists the Single Eco Mattress as a clearly specified standard foam option with a 6-inch medium-firm construction, Coolmax cover, double-sided design and 3-year warranty. Measure the frame first and choose the mattress because the specification suits the bed, not simply because Single is the lowest-priced size.
