Why should you choose this mattress?
The main reason to pick the Wunderflip is flexibility. If you're not sure whether you want a medium or firm feel, or you suspect your preference might change, the dual-sided design means you get both in one purchase, switched by removing and re-zipping the comfort layer. The memory foam layers use an open cell structure that Eve says is 5 times more breathable than standard memory foam, which means less of the heat build-up memory foam is known for. The cover's Purotex+ treatment is certified by Allergy UK, helpful if dust mites set you off. It isn't cheap, but the 200-night trial gives you a proper stretch of time to be sure.
Key features & layer details
Cover
A deep quilted fabric treated with Purotex+, made from 100% natural ingredients and certified by Allergy UK. Eve states it reduces dust mites and other nasties by up to 96.6%, which means a cleaner sleep surface if allergies bother you.
Pressure-relieving memory foam (soft side)
50mm of memory foam with an open cell structure Eve says is 5 times more breathable than standard memory foam. Its 7 drill zones let the foam adapt to your body and encourage air flow, which means contouring without quite so much warmth.
Softer foam casing
A softer foam casing on this side works alongside the softer full height springs. The result is a plusher, more squishy feel when you sleep on this face of the mattress.
Reactive spring system
1,000 full height springs, softer at one end and firmer at the other, each wrapped in a breathable fabric pocket. That pocketing helps prevent wobbles when you turn over, which means less partner disturbance.
Dual spring system
A further 1,500 springs, a combination of taller pocket springs and shorter micro pocket springs. These add an extra level of responsive support beneath the foam.
Reinforced edge support
Support runs all the way to the mattress edges. That means you can sit or sleep near the side without feeling like you might roll off.
Pressure-relieving memory foam (firm side)
The firm side gets its own 50mm of the same open cell memory foam with 7 drill zones. So you keep the pressure relief even when you flip to the sturdier feel.
Firmer foam casing
A firmer foam casing on this side pairs with the firmer full height springs. It gives a sturdier, more supported feel for those who want less sink.
Base
The base includes handles on the sides. A small touch, but it makes flipping and moving the mattress noticeably easier.

Best suited for?
Couples
Pocketed full height springs help prevent wobbles when you turn over, which means less disturbance from a partner, and edge support lets you use the full width.
Warm sleepers
Open cell memory foam that Eve says is 5 times more breathable than standard foam, with 7 drill zones, means contouring without quite so much warmth.
Allergy sufferers
The cover carries a Purotex+ treatment certified by Allergy UK, which Eve states reduces dust mites by up to 96.6%, so the sleep surface stays cleaner.
Side sleepers
Each side has 50mm of memory foam, which means pressure relief for your hips and shoulders whichever face you choose to sleep on.
Combination sleepers
Reactive springs with a dual spring system underneath add responsive support beneath the foam, which suits anyone who shifts position and wants the bed to keep up.
If you already know exactly what firmness you want, you're paying for a flippable feature you may never use, and simpler mattresses cost less. There's no Single size, so it won't suit children's rooms or guest singles. And flipping involves removing and re-zipping the comfort layer, a little more effort than a straight rotate.
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 mattress soft or firm?
Both, in a sense. It's a dual-sided design described by Eve as medium/firm: one side gives a firm feel, the other a medium feel. You switch between them by removing and re-zipping the comfort layer, so you can try both during the trial and settle on whichever suits you.
How many springs does the Eve Wunderflip have?
2,500 in total. That's 1,000 full height pocket springs, softer at one end and firmer at the other, plus 1,500 extra springs made up of taller pocket springs and shorter micro pocket springs.
Does the Eve Wunderflip come with a trial and guarantee?
Yes. Eve offers a 200-night trial, which gives you a generous stretch to try both firmness sides, and a 10-year guarantee on the mattress itself.
What sizes does the Eve Wunderflip come in?
Three sizes: UK Double, UK King and UK Super King. There's no Single option, which is worth knowing if you're shopping for a smaller bed.
Is the Eve Wunderflip good for allergy sufferers?
It's a reasonable choice. The quilted cover is treated with Purotex+, a technology certified by Allergy UK and made from 100% natural ingredients, which Eve states reduces dust mites and other nasties by up to 96.6%.
