After testing and reviewing hundreds of mattresses, I've seen my fair share of brands trying to stand out in an increasingly competitive market. Eve Sleep's Wunderflip Premium Hybrid Mattress makes a bold promise: two firmness options in a single mattress, allowing you to flip it depending on your preference. This kind of versatility is rare, but does it actually deliver a premium sleep experience? On paper it does for most sleepers, though plenty of owners find the firm side softer than they expected.
First Impressions - A Mattress with Options
The Eve Wunderflip Premium Hybrid is a lot of mattress on paper: 1,000 full height pocket springs, 1,500 more in a mix of pocket and micro pocket springs, and 50mm of memory foam. At 28cm deep, it's clear that Eve hasn't skimped on materials. The cover is a deep quilted fabric, and while it isn't removable (which is a downside for some), it does feature Purotex+ technology, which actively reduces allergens-something allergy sufferers will appreciate.
But the real selling point of this mattress is its flippable firmness levels. The firmer side is meant to provide extra support, while the softer side offers more pressure relief. Owners who've tried both sides do settle on a favourite, some on each, but the gap between the two is modest, and one calls the firm side "more medium". This flexibility could make it a fantastic choice for guest rooms or for those who aren't quite sure which firmness they prefer.
Key Features and Sleep Performance
This is a hybrid mattress, meaning it combines memory foam with pocket springs for a mix of contouring and support. Instead of using a single spring layer, Eve has gone with a dual spring system-both full-sized pocket springs and micro pocket springs. This results in:
-
Good pressure relief - The micro springs allow for finer contouring, particularly on the softer side.
-
Solid support - The deeper layer of full-sized pocket springs provides a strong foundation, especially on the firmer side.
-
Better motion isolation - If you sleep with a partner, you'll appreciate the way this mattress absorbs movement so you're not disturbed by their tossing and turning.
Two Firmness Levels - But Is It Enough?
One of the most exciting aspects of this mattress is that you get two options in a single purchase. Here's who I'd put on each side:
- Medium-Firm Side - Best suited for back and stomach sleepers who need extra spinal support. The firmer foam casing and the firmer end of the springs should give a more structured surface with less sinking.
- Medium Side - Offers better pressure relief for side sleepers, but isn't excessively soft. More than one owner who's settled on it says it's like sleeping on a cloud, while another who uses the firm side found it "a little too soft".
However, if you love ultra-plush or rock-hard mattresses, you won't find either of those extremes here. Eve has played it safe with two variations of medium comfort, which works well for most sleepers but might not be enough of a difference if you want something truly firm or ultra-soft.
Temperature Regulation
One issue with foam-heavy mattresses is that they tend to trap heat, but Eve has worked around this by incorporating open-cell foam technology and airflow drill zones. This allows for better breathability, and owners are split on how far that goes. One found it "much more cooler than my old memory foam, no more night sweating", while another called it "very warm and I do like a cool bed". Hot sleepers should use the 200-night trial before they commit.
Final Thoughts - Is the Wunderflip Premium Hybrid Worth It?
The Eve Wunderflip Premium Hybrid Mattress delivers on its promise of versatility, comfort, and quality materials. Its dual-firmness feature adds real value for those who aren't sure what firmness they prefer, and its hybrid construction provides the right mix of support and pressure relief for most sleepers.
However, it won't satisfy extreme firmness seekers -both sides land in the medium range, which works for most but won't be enough for those who want something ultra-soft or extra-firm. The lack of a washable cover is another small drawback, but not a deal-breaker if you use a mattress protector.
Ultimately, if you're looking for a well-rounded hybrid mattress with the added benefit of two comfort levels, the Wunderflip Premium Hybrid is a strong contender. It's a mattress that grows with you, adapting to changing sleep needs over time-which is something not many mattresses can offer.
