Quick verdict
Komfi Unity Comfort Eco Foam Contract Mattress looks like a sensible value pick if you want a simple foam mattress with a medium feel and a low starting price. Mattress Online lists Single, Small Double and Double sizes, with tracked prices from £103 to £147, so the main question is whether the slim profile and medium firmness suit your frame and comfort preference. If you already know you want something noticeably softer or more substantial, it is worth comparing another model first.

Product page facts to verify
The Mattress Online listing gives the most practical buying details for Komfi Unity Comfort Eco Foam Contract Mattress. It shows reflex foam construction, dual layers of pressure-relieving eco foam, a 100-night comfort trial, a 10-year guarantee and free next-day delivery to most locations. The retailer also describes the foam as made from fully recycled materials, so this is a straightforward foam mattress with a clear value angle rather than a feature-heavy build.
What the research suggests
The wider context points to a budget-to-value mattress rather than a premium-priced model. Komfi’s Unity range is described as British-made, and the visible owner reviews is positive overall at 4.6 out of 5 from up to 24 reviews. That said, the support is still best read as shopper feedback, not proof of performance, and the slim 14cm depth remains an important caveat for bed-frame, topper and bedding compatibility.
Buyer trade-offs to weigh
The upside is clear: medium feel, a low tracked price and a 100-night comfort trial. The trade-off is that the mattress is only tracked in three sizes, and the trial is conditional rather than unconditional. Compare the medium feel against your sleep position, check whether the 14cm depth works with your base and bedding, and weigh the size options against any nearby alternatives before committing.
Price and value benchmark
At £103 to £147 across the tracked Single, Small Double and Double sizes, this sits in a budget-friendly bracket. That makes it strong on entry price, especially when paired with a 100-night trial and 10-year guarantee, but the value still depends on whether the medium feel and 14cm profile suit your setup. Treat the tracked range as a guide and confirm the current checkout price, delivery cost and stock status before you buy.
How it compares with nearby alternatives
Komfi Unity Comfort Eco Foam Contract Mattress is the simpler eco-foam option, while Komfi Unity Memory Deluxe Contract Mattress is the nearby Komfi alternative to compare if you want more size choice and a different specification. The Memory Deluxe is tracked in a broader size range and starts at a higher price, so it is useful if you want to trade up from this slimmer model. Nearby alternatives such as Contract Pro Mattress and Contract Comfort Pro Mattress are also worth checking if you want a direct price comparison in the same shopping journey.
How to read the review details
The visible rating is positive at 4.6 out of 5, based on up to 24 reviews, but it should be treated as supporting evidence rather than a final verdict. The feedback signal appears broadly favourable, yet firmness reactions seem mixed in the wider context, which matters more than the score if you are sensitive to feel. Use the rating as a helpful shortlist cue, then check whether the medium feel and slim depth suit the way you sleep.
Who it suits
This mattress is best suited to value-conscious shoppers who want a simple foam mattress with a medium feel and everyday comfort. It may also suit buyers who prefer a slimmer mattress and only need one of the tracked sizes from Mattress Online: Single, Small Double or Double. The combination of £103 starting price, reflex foam construction and a 100-night trial makes it an easy shortlist option for practical budget shopping.
Who should avoid it
Skip this model if you want a plusher or more substantial feel than a medium reflex-foam mattress, or if you need king size rather than the tracked Single, Small Double and Double options. It is also a weaker fit if you want stronger certainty on firmness, because the review details is positive but not uniform, and the 14cm depth may feel too slim for shoppers expecting a deeper premium mattress. If you want a more feature-rich alternative, compare Komfi Unity Memory Deluxe Contract Mattress or another model in a higher price band before buying.
Comfort and support
Komfi Unity Comfort Eco Foam Contract Mattress uses reflex foam support with dual layers of pressure-relieving eco foam, and the retailer describes the feel as medium. In practical terms, that usually points to a balanced surface rather than a plush or heavily engineered mattress. The 14cm depth suggests a slim build, so sleep-position fit matters: side sleepers may want to check whether the feel is supportive enough for them, while back or front sleepers may prefer the more straightforward, firmer character of a simple foam mattress. This is a comfort and support review, not a medical claim, so the safest approach is to match the feel to your normal sleep position and setup.
Value verdict
The value case is strong if you want a low-cost mattress with a clear trial and guarantee: £103-£147, a 100-night comfort trial and a 10-year guarantee. Add in the positive 4.6 review details and the medium-feel, reflex-foam specification, and this looks like a practical value buy rather than a premium feature mattress. Before checkout, still confirm the final size price, delivery details and whether the 14cm depth works with your bed base, topper and bedding.

Questions about this mattress
Is Komfi Unity Comfort Eco Foam Contract Mattress worth buying for the price?
It looks good value if you want a medium-feel foam mattress and a low entry price. With tracked prices from £103 to £147, plus a 100-night comfort trial and 10-year guarantee, the value case is strongest for practical budget shoppers rather than people looking for a premium build.
What size options are available and do prices change by size?
The tracked retailer sizes are Single, Small Double and Double, and the prices run from £103 to £147 depending on size. Because checkout pricing can change, it is worth confirming the exact size you need before you buy.
How firm does the mattress feel, and who is the medium feel likely to suit?
The retailer lists this Komfi mattress as medium firmness with reflex foam construction. That usually suits shoppers who want a balanced feel rather than something very soft or very firm, but it is sensible to think about your sleep position and whether you prefer a slimmer mattress.
Is the 100-night comfort trial unconditional?
No. The supplied trial wording is conditional, so it should not be treated as a simple no-questions-asked refund. Check the current terms at checkout so you understand the requirements, any exchange rules and how the mattress protector condition applies.
Does the 14cm depth matter for bed frame or bedding compatibility?
Yes, it can. A 14cm mattress is relatively slim, so it is worth checking your bed frame, topper and bedding before buying. That is especially important if you want a deeper mattress feel or if your setup has height-sensitive fittings.
