The Emma Original Mattress and the Eve Original Mattress are both medium firm all-rounders with 200-night trials, but they take very different routes to get there.
You've narrowed it down to two of the most searched-for mattresses in the UK, and on paper they look close. Both offer medium firm support, a 200-night trial and a 10-year guarantee. The difference sits in what they're made of: the Emma Original is a 25cm hybrid with a 5-zone pocket spring core under its foam layers, while the Eve Original is all foam, with seven contour zones cut into its base layer.
Our verdict goes to the Eve Original. It resolves the cooling question more convincingly, with a moisture-wicking top cover and breathable evecomfort foam, and it comes in nine sizes to the Emma's seven, including everything from UK Single up to Emperor. If you sleep warm or need a less common size, the Eve is the stronger pick.
That said, the Emma is the clear winner on value. It sits well below the typical price for a hybrid, where the Eve costs noticeably more than most foam mattresses. If budget is your first filter, read on before deciding.
Our verdict at a glance: which mattress wins?
The Eve Original wins on the dimensions you feel nightly, resolving cooling with its moisture-wicking cover and breathable foam while offering nine sizes to the Emma's seven.
RUNNER UP
You want springs as well as foam
The Emma's 5-zone pocket spring core adapts to different parts of your body, which means your hips can sink slightly while your shoulders stay cushioned, with a bounce that all-foam designs can't replicate.
You care about value
The Emma sits well under half the typical price for a hybrid mattress, so you're getting a spring-and-foam build for less than most rivals charge.
You like practical touches
The cover is removable and washable, and a comfort foam edge around the springs firms up the perimeter, so you can sit or sleep near the side without feeling like you might roll off.
WINNER
You sleep warm
The Eve pairs a moisture-wicking top cover with breathable evecomfort foam, which means it's designed to keep clamminess at bay, and it won the cooling comparison here.
You need a wider choice of sizes
Nine sizes against the Emma's seven, running from UK Single up to Emperor plus EU options, so unusual bed frames are better catered for.
You want independent backing
The Eve carries a Which? Best Buy certification, which is reassuring if you'd rather trust independent assessment than brand claims alone.

On construction alone, this one is genuinely close and we don't call a winner. The Emma is a 25cm six-layer hybrid, foam over a 5-zone pocket spring core, while the Eve is a five-layer all-foam build with seven contour zones cut into its base. Neither approach is objectively better; springs give bounce and the Eve's zoned foam targets pressure at the shoulders and hips. Pick the feel you already know you like.

How firm are both mattresses?
Which mattress feels better?
Both sit in similar territory. Emma calls the Original medium firm, a balance of cushioning and support that suits most sleeping positions. Eve describes medium-firm support with a lightly cushioned feel, which means it holds you level while giving a softer first impression when you lie down. In practice, side sleepers should get on with either: the Emma's zoned springs let hips sink slightly while shoulders stay cushioned, and the Eve's memory layer plus contoured base eases pressure at the same points. If you like a properly firm, unyielding surface, the Eve's lightly cushioned top may feel a little too soft. If you want a distinctly soft, sink-in feel, the Emma may feel slightly too supportive.
Other important factors to consider before buying.
Beyond feel, the practical terms are unusually well matched here. Both brands offer a 200-night trial and a 10-year guarantee, so neither gives you a reason to rush the decision. The table below sets out the details side by side.

The Eve Original takes the win. Three dimensions separated these two, and the Eve claimed the ones that shape how the mattress actually feels night to night: cooling, thanks to its moisture-wicking top cover and breathable evecomfort foam, and choice, with nine sizes from UK Single to Emperor against the Emma's seven. The Emma Original wins convincingly on value, sitting well below the typical hybrid price where the Eve costs more than most foam mattresses, so it remains the sensible pick if budget leads your decision. Everything else, from construction quality to trial and guarantee terms, is too close to separate them. Yes, the Eve asks more of your wallet, but the cooling design, size range and Which? Best Buy backing are what you get for it. For most buyers weighing these two, the Eve is the one to order.
Decision helper
Consider your primary need: a cooler-sleeping mattress in a wider range of sizes, or a spring-based build at a much lower price.

Is the Emma Original or the Eve Original better?
The Eve Original comes out ahead in our comparison, winning on cooling and size choice. Its moisture-wicking top cover and breathable evecomfort foam give it the edge for warm sleepers, and it comes in nine sizes to the Emma's seven. The Emma Original wins on value, though, sitting well below typical hybrid prices.
Which is better for hot sleepers, Emma or Eve?
The Eve Original won the cooling comparison. It has a moisture-wicking top cover designed to stop you getting hot and clammy, plus ultra breathable evecomfort foam beneath it. Do bear in mind Eve's own guidance that foam generally runs warmer than sprung designs, so very hot sleepers should weigh that against the Emma's hybrid build.
Is the Emma Original cheaper than the Eve Original?
Yes, the Emma Original comes in considerably lower for a comparable size, and it sits well below the typical price for a hybrid mattress. The Eve costs more than most all-foam options. Prices change often, so check the live price tables on this page for today's figures in your size.
Do the Emma and Eve mattresses have the same trial and guarantee?
Yes, they match exactly. Both the Emma Original and the Eve Original come with a 200-night home trial and a 10-year guarantee, so neither brand gives you an advantage on peace of mind. That's a proper stretch of time to decide at home rather than in a showroom, whichever you pick.
What is the difference between the Emma Original and the Eve Original?
Construction is the big one. The Emma Original is a 25cm hybrid with foam layers over a 5-zone pocket spring core, giving a touch of bounce and a foam-reinforced edge. The Eve Original is all foam, with a memory layer and seven contour zones cut into its base to ease pressure at your shoulders and hips.
