Why should you choose this mattress?
A medium tension suits most sleepers, although lightweight side sleepers sometimes prefer something a touch softer and heavier back sleepers may want firmer support. The pocket spring construction should help with motion isolation, useful if you share a bed with a restless partner. Yes, the price is high, but Hypnos is a long-established British bedmaker and you're paying for that pedigree. If you buy through Mattressman, they list a 60-night sleep trial and free next day delivery, with a handling time of 0 to 1 day and transit of 1 to 3 days. Do check those terms still apply at your chosen retailer, as they're the shop's offer rather than the manufacturer's.
Key features & layer details
We’re still collecting information on this mattress. Unfortunately, we don’t have its key features yet.
Best suited for?
Couples
Pocket spring construction should help with motion isolation, so you are less likely to feel a restless partner turning over beside you.
Combination sleepers
Medium tension suits most sleepers, which makes it a sensible all-round feel if you move between positions through the night.
Back sleepers
A medium feel gives a balanced level of support for average-weight back sleepers, though heavier people may want something firmer.
Side sleepers
Medium tension should cushion the shoulders and hips for most side sleepers, although lightweight ones may prefer something a touch softer.
If you're on a tight budget, the starting price puts this out of reach when perfectly good mattresses exist for far less. Anyone who wants full transparency on materials and depth before buying may also feel uneasy, as detailed construction specs aren't published on the listing we reviewed.
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
Is the Hypnos Legacy 3 medium or firm?
It's listed as a medium tension, which suits most sleeping positions. Back and side sleepers generally get on well with a medium, although lighter side sleepers may find it slightly firmer than expected, as body weight affects how any mattress feels.
Does the Hypnos Legacy 3 come with a sleep trial?
Mattressman lists a 60-night sleep trial on this mattress. That's the retailer's own offer rather than a Hypnos guarantee, so if you buy elsewhere, check that seller's returns policy before ordering.
What sizes does the Hypnos Legacy 3 Medium come in?
It's available in UK Single, Double, King and Super King.
How quickly can the Hypnos Legacy 3 be delivered?
Mattressman lists free next day delivery, with a handling time of 0 to 1 day and transit of 1 to 3 days. These are that retailer's terms, so delivery may differ if you buy from another shop.
