Eve Wunderflip Ultimate Hybrid Sleep Mattress
The Eve Wunderflip Ultimate Hybrid is a flippable mattress with two comfort levels: a softer, more squishy side and a firmer, more supported side, which means you can turn it over rather than guess your ideal feel before buying.

The Wunderflip Ultimate Hybrid is positioned by Eve as medium/firm overall. Inside sits a mix of latex, memory foam and 3,000 springs in total, combining 1,000 full height Reactive springs with 2,000 extra pocket and micro pocket springs. It comes in Double, King and Super King. It sits at the pricier end, but the two-in-one design and a 200-night trial give you room to get the choice right.

Why should you choose this mattress?
The strongest reason to choose the Wunderflip is flexibility. If you genuinely don't know whether you prefer a plush or a firm feel, flipping the mattress lets you try both at home during Eve's 200-night trial. The plant-based latex layer moulds to your body and helps keep your spine aligned, while the 30mm memory foam layer has an open cell structure that Eve says is 5 times more breathable than standard memory foam, so it should sleep cooler than older-style foam. The cover is treated with Purotex+, certified by Allergy UK, which reduces dust mites by up to 96.6%: useful if allergies disturb your sleep. Both sides have reinforced edge support, and a 10-year guarantee backs it all up.
Key features & layer details
Cover
A deep quilted fabric treated with Purotex+, certified by Allergy UK to reduce dust mites and nasties by up to 96.6%. It also has an Adaptive fabric treatment to regulate temperature and wick moisture, which means less clammy overheating on warm nights.
Latex layer
Plant-based, hypoallergenic latex that moulds to your body and relieves pressure. It also helps keep your spine aligned, which you'll feel as gentle contouring rather than sinking.
Pressure-relieving memory foam
30mm of memory foam with an open cell structure and 7 drill zones, which Eve says is 5 times more breathable than standard memory foam. The zones adapt to your body and encourage airflow.
Dual spring system
2,000 extra springs, a combination of tall pocket springs and shorter micro pocket springs. Together they add responsive, targeted support beneath the comfort layers.
Reinforced edge support (firmer side)
Reinforced edges on the firmer side, which means you can sit or sleep near the edge without feeling like you'll roll off.
Firmer foam
A firmer foam casing on one side for a sturdier, more supported sleep. This is the side to use if you like a solid, stable feel.
Reactive spring system
1,000 full height springs, softer at one end and firmer at the other, each wrapped in a breathable fabric pocket. The pockets help prevent motion transfer, so a restless partner is less likely to wake you.
Reinforced edge support (softer side)
Reinforced edges on the softer side too, so edge stability doesn't change when you flip the mattress.
Softer foam
A softer foam casing on the other side for a plushier, more squishy sleep. Flip to this side if you prefer to sink in a little.
Base
A base with handy handles on the sides, which makes flipping and moving the mattress noticeably easier.

Best suited for?
Allergy sufferers
The cover is treated with Purotex+, certified by Allergy UK to reduce dust mites by up to 96.6%, and the latex layer is hypoallergenic.
Warm sleepers
Open cell memory foam with 7 drill zones and an Adaptive cover that wicks moisture should mean less clammy overheating on warm nights.
Couples
Each of the 1,000 full height springs sits in its own fabric pocket, which helps prevent motion transfer so a restless partner is less likely to wake you.
Combination sleepers
Reinforced edges on both sides keep edge stability the same whichever way up it is, so shifting position near the edge feels secure.
Side sleepers
The plant-based latex layer moulds to your body and relieves pressure, which you'll feel as gentle contouring, with a softer side to flip to.
This isn't the mattress for tight budgets: it's a serious spend. There's no UK Single, so it won't suit children's rooms or narrow spare beds. And if you already know exactly what firmness you want, you may be paying for a flippable feature you'll never use.
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 Eve Wunderflip soft or firm?
Both, in a sense. Eve rates it medium/firm overall, but the mattress is flippable with a softer, plushier side and a firmer, more supported side. You choose the feel by turning it over, and you can switch again if your preference changes.
How many springs does the Eve Wunderflip have?
3,000 in total. That's 1,000 full height Reactive springs, softer at one end and firmer at the other, plus a dual spring system of 2,000 extra pocket and micro pocket springs, a mix of taller pocket springs and shorter micro springs.
Does the Eve Wunderflip come with a trial?
Yes. Eve offers a 200-night trial, which is longer than most brands offer, so you have time to try both the softer and firmer sides at home. It's also backed by a 10-year guarantee.
Is the Eve Wunderflip good for allergy sufferers?
It has credible credentials here. The cover's Purotex+ treatment is certified by Allergy UK and reduces dust mites by up to 96.6%, and the latex layer is hypoallergenic. That's reassuring, although no mattress can eliminate allergens entirely.
How is the Eve Wunderflip delivered?
It arrives vacuum-sealed in a box, delivered free to your doorstep, though some areas may be charged. Once unrolled it expands to full size within a few hours. Handles on the base make it easier to move and flip.
