Quick verdict
This is a compare-first shortlist rather than a single-winner ranking. The main starting points are Komfi GelMed Comfort Mattress, KomfiMed Pro Medium Mattress and Komfi GelMed Ortho Mattress, but the right pick depends on the feel you want, the size you need and whether the current price justifies the specification. Current starting prices run from £103 to £1,055, so it is worth comparing the same size and similar firmness before deciding whether a higher price brings a meaningful upgrade.
Top picks to compare
Start with Komfi GelMed Comfort Mattress (£645-£1,055), KomfiMed Pro Medium Mattress (£504-£898), Komfi GelMed Ortho Mattress (£768-£874) because they give you a focused set of current retailer options to compare. The visible price range is £103-£1,055, so check whether the extra spend buys a useful specification difference rather than only a different brand or finish. The shortlist includes Komfi, which helps you compare familiar brands against specification, delivery and value.

What the shortlist evidence supports
The five mattresses on this page span three constructions: standard Mattress, Orthopaedic and Memory Foam. That matters because a foam-led Komfi Unity model will not compare like-for-like with a GelMed hybrid-style model or the firmer GelMed Ortho, even when the brand name is the same. The review picture is uneven: Komfi Unity Comfort Eco Foam Mattress has the clearest visible review volume at up to 24 reviews and a 4.6 average, while several higher-priced GelMed models show very limited visible feedback. KomfiMed Pro Medium Mattress and the GelMed models also show 100-night comfort trial wording and a 10-year guarantee on their product pages, but that should still be checked on the live listing before ordering.
Buyer trade-offs to compare before buying
The simplest firmness ladder in this set is Medium, Medium to Firm and Firm, so start by choosing how much support you want rather than chasing the lowest price. Komfi GelMed Comfort Mattress is the medium-feel starting point, KomfiMed Pro Medium Mattress sits in the medium-to-firm zone, and Komfi GelMed Ortho Mattress is the firmest option on the shortlist. Construction also changes the decision: Unity models are foam-led and lower cost, while the GelMed models mix more materials and sit higher in the range. Because the price spread is so wide, compare the same size and check whether the extra spend buys a better fit for your frame, room access and preferred feel rather than only a different model name.
Why these five Komfi mattresses made the shortlist
Komfi has enough current range depth at Mattress Online to make a focused brand shortlist useful, and these five picks cover the clearest feel and construction differences within the brand. They are not an exhaustive verdict on every Komfi mattress, but they do give shoppers a practical compare set: two medium-leaning GelMed options, one firm orthopaedic model and two lower-cost Unity foam routes. That makes the shortlist useful for comparing specification, price and size coverage without opening every product page first, while still keeping the advice cautious because the evidence is limited and not a head-to-head lab comparison.
What the shortlist shows at a glance
The visible starting price range is £103 to £1,055, with a median starting price of £504 across the current Komfi set. Komfi Unity Comfort Eco Foam Mattress is the lowest-priced option and has the strongest visible review details in the group, with a 4.6 average and up to 24 reviews. By contrast, most of the higher-priced GelMed and KomfiMed models show only a small number of visible reviews, so a bigger price tag does not automatically mean more shopper confidence. Size coverage also varies: Komfi GelMed Ortho Mattress is only shown in King Size and Super King, while the other shortlisted mattresses offer broader size ranges.
How to choose between these Komfi mattresses
If you want a medium-feel Komfi mattress, start with Komfi GelMed Comfort Mattress or KomfiMed Pro Medium Mattress and compare their exact size prices on the live product page. If you prefer firmer support, Komfi GelMed Ortho Mattress is the clearest match on the shortlist, but its limited size coverage means it suits fewer shoppers. For tighter budgets, Komfi Unity Comfort Eco Foam Mattress is the entry-level comparison route, while Komfi Unity Memory Deluxe Mattress gives you another lower-cost option to compare if you want to stay in the Unity range. Before buying, check the retailer’s stated firmness, the exact size you need, delivery access and whether the trial and guarantee wording still matches the listing.
Where the best value may sit
Value here is about fit plus confidence, not the lowest sticker price. The £103-£1,055 spread means a dearer mattress only makes sense if it gives you a clearly better feel match, a stronger construction preference or a size that fits your bed frame better. Komfi Unity Comfort Eco Foam Mattress looks strongest on price and visible review volume, while the GelMed models ask for a much bigger outlay and should be judged on whether the hybrid-style build and trial wording are worth the extra spend for your needs. As always, check the retailer for latest price and availability, because these figures can move by size and over time.

Buying questions
Which Komfi mattress is best for a medium feel?
The clearest medium-feel starting point is Komfi GelMed Comfort Mattress. KomfiMed Pro Medium Mattress is the other obvious comparison if you want something closer to medium-to-firm, so compare both by size and price before deciding.
Which shortlist option suits firmer support or an orthopaedic-style feel?
Komfi GelMed Ortho Mattress is the firmest option in the current shortlist and the only orthopaedic model shown here. It is also the least flexible on size, with only King Size and Super King visible, so check that fit before you commit.
Is the cheapest Komfi mattress automatically the best value?
Not necessarily. Komfi Unity Comfort Eco Foam Mattress is the lowest-priced option and has the strongest visible review volume, but the right value choice depends on the size you need, the firmness you want and whether a more expensive model adds a clear specification benefit.
Why do some higher-priced models have fewer visible reviews?
That can happen when a product is newer, narrower in size coverage or simply has less public feedback shown on the retailer page. In this Komfi set, several higher-priced GelMed models have only very limited visible review counts, so price alone is not a reliable confidence marker.
Do I need to check size, trial and guarantee on the live product page before buying?
Yes. Size availability, trial wording and guarantee terms can differ by exact model and may change over time. It is especially important for Komfi GelMed Ortho Mattress because its size range is limited, and for the GelMed and KomfiMed models because the trial and guarantee wording should be confirmed before purchase.
