Why should you choose this mattress?
The top layer is designed to maximise airflow and regulate body temperature, which makes it a sensible pick if you often wake up too warm. Below it sits a cushioned layer for comfort and spinal alignment, then a responsive support layer that keeps your body well positioned. Medium firmness is a safe middle ground for many back and side sleepers. The cover is removable and washable, and the mattress is dust mite resistant, so it's easy to keep fresh. You rotate it rather than flip it, which keeps care simple. At 30cm deep, it should suit most standard bed frames.

Best suited for?
Warm sleepers
The breathable top layer is designed to maximise airflow and regulate body temperature, which means you should be less likely to wake up too warm.
Side sleepers
Medium firmness and a cushioned comfort layer below the top give a softer feel under you while the base layer keeps your body well positioned.
Back sleepers
A medium feel is a safe middle ground, and the responsive support layer underneath keeps your body evenly held without sinking too far.
Allergy sufferers
The mattress is dust mite resistant and has a removable, washable knitted cover, which makes it easy to keep fresh over time.
Budget buyers
It is described as affordable for a middle-of-the-road medium feel, and it still comes in five UK sizes with a 10-year warranty.
If you prefer sleeping on a firm mattress, this might not be the best choice. It's rated medium, so heavier sleepers who want a very supportive, rigid feel may find it gives too much. It's all foam, with no springs, so anyone who likes the bounce of a spring mattress may miss it.
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 Vitality Max?
It's rated medium, a balanced feel that suits many back and side sleepers. If you want a firm, rigid surface, or a very soft cushioned one, a different firmness would suit you better.
What sizes does the Komfi Vitality Max come in?
It comes in UK Single, UK Small Double, UK Double, UK King and UK Super King. That covers solo sleepers and couples, so you can match it to most standard UK bed frames.
How deep is the Komfi Vitality Max?
It's 30cm deep. That's a reasonable height for most standard bed frames, though if your frame has a shallow recess, check the measurements before you order.
Is the Komfi Vitality Max good for hot sleepers?
It's designed with sleeping warm in mind. Its top layer is built to maximise airflow and regulate body temperature, which should help reduce overheating, although how cool you feel will still vary from person to person.
Does the Komfi Vitality Max have a trial or guarantee?
Komfi gives a 10-year warranty. Archers Sleepcentre offers its own 60-night comfort guarantee, which requires a Purecare mattress protector to be bought. That trial is the retailer's offer, not Komfi's.
