The Eve Original Mattress and the Tempur Ease 20cm Mattress are both all-foam designs, but they feel and behave quite differently once you lie down.
On paper these two look similar. Both are memory foam mattresses with a 10-year guarantee, both sit at a comparable point in the market, and both offer a firmer-than-average feel. Look a little closer, though, and they take different approaches: the Eve Original layers springy, breathable evecomfort foam over a zoned base, while the Tempur Ease leads with Tempur's Adapt foam, which responds to your weight and body temperature for that signature slow-sinking feel.
Across the dimensions that separated them, the Eve Original comes out the winner. It has the more considered build, with five layers including a base cut with seven contour zones for shoulders and hips. It also handles heat better, with a moisture-wicking top cover and breathable comfort foam, where the dense Tempur foam draws mentions of warmth retention in owner reviews. Add a wider range of sizes and a longer trial, and the Eve is the one to buy for most people.
That said, the Tempur has a genuine pull of its own. If you specifically want that enveloping, body-moulding Tempur feel, nothing about the Eve will replicate it.
Our verdict at a glance: which mattress wins?
The Eve Original wins on cooling, layer design and choice, with double the at-home trial time as the deciding practical edge.
WINNER
It runs cooler than the Tempur
The Eve's moisture-wicking top cover and breathable evecomfort foam are designed to keep clamminess at bay, which means warm sleepers get an easier ride than they would on the Tempur's denser foam, where owner reviews mention warmth retention.
The zoned base targets pressure where it builds
The base layer has seven contour zones cut in to ease pressure from your shoulders and hips, so side and back sleepers get support shaped to where their body needs it.
You get more time and more sizes
A 200-night trial gives you twice as long at home as the Tempur's 100 nights, and nine sizes from UK Single up to Emperor mean unusual bed frames are better catered for.
RUNNER UP
You want the Tempur Adapt feel specifically
The 3cm Adapt layer has pressure-sensitive cells that respond to your weight and body temperature, so the surface gradually moulds around you rather than pushing back. The Eve feels lightly cushioned by comparison, never enveloping.
You share a bed with a restless partner
An 8cm memory foam layer sits beneath the surface purely to absorb motion, which means you're less likely to feel your partner turning over during the night.

Both are all-foam builds, and on construction alone this one is genuinely close. The Eve uses five layers, pairing springy evecomfort foam and a memory layer with a zoned base, while the 20cm Tempur keeps things simpler with three layers topped by its Adapt foam. Neither approach is wrong. They just produce different feels: the Eve is lightly cushioned and responsive, the Tempur slow-sinking and enveloping.

How firm are both mattresses?
Which mattress feels better?
The Eve Original offers medium-firm support with a lightly cushioned feel, which means it holds you level while giving a soft first impression when you lie down. That combination suits most sleep positions, and the seven contour zones in the base take pressure off shoulders and hips, a real help for side sleepers. The Tempur Ease is medium to firm, and its Adapt foam spreads pressure evenly across hips and shoulders, something side and back sleepers with aches tend to feel quickly. Lightweight sleepers hoping for a plush surface may find it firmer than expected, and anyone who likes a responsive surface may find the slow sink a little enveloping.
Other important factors to consider before buying.
Beyond feel, the practical terms deserve a look before you commit. Both mattresses carry a 10-year guarantee, but the trials differ, and that gap matters more than it sounds when you're buying unseen. The table below sets out how the two compare.

Prices and sizes for both mattresses
Both sit above the typical price for a memory foam mattress, the Eve slightly more so, though its trial, guarantee and Which? Best Buy backing go some way to explaining the gap. Check the live tables below for today's prices.
Eve Original Mattress
Tempur Ease 20cm Mattress
The Eve Original is the winner here, and the reasons are practical rather than dramatic. It took the layers dimension with a five-layer build that includes a zoned base for shoulder and hip pressure relief, and it took cooling thanks to its moisture-wicking cover and breathable comfort foam, where the Tempur's dense foam draws warmth complaints from owners. It also offers more choice, with nine sizes against seven and a 200-night trial against 100. The Tempur Ease is still a sound buy for one specific person: someone who wants the slow-sinking, body-moulding Adapt foam feel, especially a couple bothered by partner disturbance. If that's you, the Tempur delivers something the Eve doesn't. For everyone else, the Eve is the safer, cooler, more flexible pick.
Decision helper
Consider your primary need: a cooler, lightly cushioned foam mattress with a longer trial, or the slow-sinking, motion-absorbing Tempur feel.
WINNER
It runs cooler than the Tempur
The Eve's moisture-wicking top cover and breathable evecomfort foam are designed to keep clamminess at bay, which means warm sleepers get an easier ride than they would on the Tempur's denser foam, where owner reviews mention warmth retention.
The zoned base targets pressure where it builds
The base layer has seven contour zones cut in to ease pressure from your shoulders and hips, so side and back sleepers get support shaped to where their body needs it.
You get more time and more sizes
A 200-night trial gives you twice as long at home as the Tempur's 100 nights, and nine sizes from UK Single up to Emperor mean unusual bed frames are better catered for.
RUNNER UP
You want the Tempur Adapt feel specifically
The 3cm Adapt layer has pressure-sensitive cells that respond to your weight and body temperature, so the surface gradually moulds around you rather than pushing back. The Eve feels lightly cushioned by comparison, never enveloping.
You share a bed with a restless partner
An 8cm memory foam layer sits beneath the surface purely to absorb motion, which means you're less likely to feel your partner turning over during the night.
Is the Eve Original or the Tempur Ease better for hot sleepers?
The Eve Original is the better pick for hot sleepers. Its moisture-wicking top cover and breathable evecomfort foam are designed to stop you getting clammy, while owner reviews of the Tempur Ease mention warmth retention, a known trait of dense memory foam. Neither will feel as airy as a sprung mattress, but the Eve handles heat noticeably better.
Which is firmer, the Eve Original or the Tempur Ease?
The Tempur Ease is the firmer-feeling of the two. It's rated medium to firm, and lightweight sleepers may find it firmer than expected. The Eve Original is medium-firm underneath but has a lightly cushioned feel on top, so it gives a softer first impression when you lie down while still holding you level.
Do the Eve Original and Tempur Ease have the same trial and guarantee?
Both come with a 10-year guarantee, but the trials differ. The Eve Original gives you 200 nights at home to decide, while the Tempur Ease offers 100 nights through the manufacturer. If you're nervous about buying a mattress unseen, that extra time with the Eve takes more of the risk out.
Is the Tempur Ease good for couples?
Yes, partner disturbance is one of its strengths. The Tempur Ease has an 8cm memory foam layer specifically there to absorb motion as you move, so a restless partner is less likely to wake you. The Eve Original is an all-foam design too, but it doesn't have a dedicated motion-absorbing layer in its build.
Which comes in more sizes, the Eve Original or the Tempur Ease?
The Eve Original offers more choice, with nine sizes running from UK Single up to Emperor, plus EU sizes. The Tempur Ease comes in seven, from UK Small Single to Super King with an EU Single. If you have an unusual bed frame or want something larger than a Super King, the Eve is the one to look at.
