At 17cm, the Komfi Unity Memory Deluxe is slimmer than many mattresses, so it suits lighter sleepers, children's rooms and guest beds particularly well. It's handcrafted in the UK, and Komfi is a National Bed Federation Approved Brand, which offers some reassurance at its budget-friendly price.

Why should you choose this mattress?
This is a sensible pick if you want memory foam comfort without spending a lot. The Neuform top layer is designed to lift pressure off joints and reduce heat, which means less of the warm, stuck feeling memory foam is sometimes known for. The reflex foam core absorbs movement, so if you share a bed you should feel less disturbance when your partner shifts. There's also an environmental angle: the base is Ecofoam made from recycled foam and is itself fully recyclable. Mattress Online lists a 100-night trial and a 5 year guarantee with it, which gives you a decent safety net, though those are that retailer's terms rather than Komfi's own.
Key features & layer details
Neuform Memory Foam
A specialised Neuform memory foam layer sits at the top, cushioning you and lifting pressure off joints and muscles. It's also designed to reduce heat, which means a slightly cooler night than traditional memory foam tends to give.
Reflex Foam
At the heart of the mattress, this soft, flexible reflex foam shapes around your contours. It absorbs movement and limits motion transfer, so a restless partner is less likely to wake you.
Ecofoam
The base layer is Ecofoam, made from recycled foam and fully recyclable. It's a modest but genuine plus if sustainability matters to you.

Best suited for?
Lighter sleepers
The slim 17cm depth suits lighter bodies, which means you are unlikely to press through the top layer to the firmer base.
Couples
A reflex foam core absorbs movement and limits motion transfer, so you should feel less disturbance when your partner shifts in the night.
Guest rooms
Slimmer than many mattresses and backed by a 100-night trial, it makes a sensible spare bed for occasional visitors.
Eco-conscious buyers
The base layer is Ecofoam made from recycled foam and is fully recyclable, which gives sustainability-minded shoppers a genuine green point.
Warm sleepers
The Neuform memory foam top layer is designed to reduce heat, so you should get a cooler night than traditional memory foam gives.
At 17cm deep, it's a little shallow for heavier adults, who may press through to the firmer base. If you love a plush, sink-in feel, the medium to firm rating will likely feel harder than you'd like, and some owners do describe it as very firm. If you prefer a springy, traditional pocket-sprung feel, this might not be the best choice either.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
How firm is the Komfi Unity Memory Deluxe mattress?
It's rated medium to firm. In practice the memory foam top gives some initial cushioning before you reach the firmer support beneath. Some owner reviews describe it as very firm, so lightweight side sleepers may find it a touch too solid for their liking.
Does the Komfi Unity Memory Deluxe come with a trial or guarantee?
Mattress Online lists a 100-night trial and a 5 Year Guarantee with this mattress. These are the retailer's own terms, so if you buy elsewhere, check what that seller offers before ordering.
What sizes is the Komfi Unity Memory Deluxe available in?
It comes in UK Single, Small Double, Double and King.
Is the Komfi Unity Memory Deluxe good for hot sleepers?
It should be better than average for a memory foam mattress. The Neuform top layer is designed to reduce heat for a cooler sleeping environment, though all-foam mattresses generally still sleep warmer than sprung ones, so very hot sleepers may want a hybrid instead.
How is the Komfi Unity Memory Deluxe delivered?
Mattress Online offers free next day weekday delivery, or free weekday or weekend delivery ordered up to 60 days ahead, with a two-hour slot and a call on delivery day. Room delivery and old mattress recycling cost extra. These are the retailer's services, not Komfi's.
