The Eve Original Mattress and the Otty Hybrid Mattress solve the same problem in two different ways, so here is how to pick between them.
You've narrowed it down to an all-foam mattress and a hybrid, which is really a choice between two feels. The Eve Original is a five-layer foam design with medium-firm support and a lightly cushioned top, so you get that gentle initial softness before the denser base holds you level. The Otty Hybrid takes a different route: memory foam over 16cm encapsulated pocket springs, up to 2,000 of them, for a more responsive, pushed-back feel that Otty rates at 7/10 firmness.
There is no single winner here, and it would be dishonest to invent one. The right answer depends on what you value most. If a soft-topped foam feel with a long 200-night home trial appeals, the Eve is the one to buy. If you want springy support, firmer edges and better value against comparable mattresses, take the Otty.
Below, we break down where each one genuinely differs, so you can match the mattress to the way you actually sleep.
Our verdict at a glance: which mattress wins?
It depends, because the Otty wins clearly on value while the Eve offers double the trial length and a softer, more forgiving surface.
WINNER
A 200-night trial gives you a full two seasons to decide
Eve's 200-night trial is twice the length of Otty's, which means you can sleep on it through both warm and cold months before committing.
Seven contour zones cut into the base layer
The denser base foam has seven zones cut in to ease pressure from your shoulders and hips, which you'll feel as more give where your body is heaviest.
Independent backing from Which?
It carries a Which? Best Buy certification, reassuring if you'd rather trust independent testing than brand claims alone.
RUNNER UP
Unusually tall 16cm pocket springs
The encapsulated spring layer gives genuine bounce and support, with low motion transfer, which means a restless partner disturbs you less.
Firmer edges from encapsulation
Encapsulated springs plus the side support layer give you a usable edge-to-edge sleeping surface, so you can sit or sleep near the side without feeling you'll roll off.
Better value against its peers
The Otty sits slightly below the typical price for a hybrid, while the Eve sits well above the typical price for a foam mattress, so your money stretches further here.

On construction alone this is too close to call, because both are well thought out for what they are. The Eve stacks five foam layers, from a moisture-wicking cover down through springy evecomfort foam, a memory layer and a zoned base. The Otty runs six layers across 25cm, with heat regulating memory foam sitting on 16cm encapsulated pocket springs. Choose on feel rather than build quality: slow, cushioned contouring from the Eve, responsive push-back from the Otty.
Construction verdict: which wins on build?

Choose on feel rather than build quality: slow, cushioned contouring from the Eve, responsive push-back from the Otty.
Which mattress feels better?
Both sit in medium-firm territory, but they arrive there differently. The Eve pairs medium-firm support with a lightly cushioned feel, which means the surface gives a soft first impression before the base foam takes over. That suits side sleepers and anyone who dislikes a hard landing, though if you like a properly firm, unyielding surface it may feel a little too soft on top. The Otty is rated Medium-Firm at 7/10, and it feels it. The tall spring layer pushes back rather than letting you settle in, which is a benefit for back and front sleepers who need spinal support. Lightweight side sleepers may find it slightly too firm on the shoulders and hips, so if that's you, the Eve's cushioned top is the safer bet.
Other important factors to consider before buying.
Beyond feel, the practical terms deserve a look before you buy. Both brands back their mattress with a 10-year guarantee, but the trials differ meaningfully. The table below sets out what each offers.

Do bear in mind that as these mattresses come delivered in sealed boxes they will have a rubbery smell when first extracted. They need a good few hours in a room with the windows open before you sleep on them.

There is no outright winner here, and that's the honest answer. The choice depends on the feel you want and how you weigh value against trial length. The Otty Hybrid took the value dimension clearly: it sits slightly under the typical hybrid price, while the Eve sits well above the going rate for foam, so pound for pound the Otty gives you more, including 2,000 encapsulated springs and firmer edges. The Eve answers back with a 200-night trial, double Otty's 100 nights, plus a Which? Best Buy behind it. So take the Otty if you sleep on your back or front, share a bed, or want springy support at a fair price. Take the Eve if you sleep on your side, prefer a cushioned foam feel, and want the longest possible run to decide at home.
Decision helper
Consider your primary need: responsive spring support and stronger value from the Otty, versus a cushioned foam feel and a 200-night trial from the Eve.
WINNER
A 200-night trial gives you a full two seasons to decide
Eve's 200-night trial is twice the length of Otty's, which means you can sleep on it through both warm and cold months before committing.

Is the Eve Original or the Otty Hybrid better for side sleepers?
The Eve Original is the safer pick for side sleepers. Its lightly cushioned top and the seven contour zones cut into the base layer ease pressure from shoulders and hips. The Otty Hybrid is rated Medium-Firm at 7/10, and lightweight side sleepers may find it a little too firm at those same pressure points.
Which is better for hot sleepers, Eve Original or Otty Hybrid?
Both make a genuine effort here, and our comparison found this dimension too close to call. The Eve has a moisture-wicking top cover and breathable evecomfort foam, while the Otty pairs heat regulating memory foam with airflow side supports. If overheating is your main worry, either is a reasonable choice, so decide on feel and value instead.
How long are the trials on the Eve Original and Otty Hybrid?
The Eve Original comes with a 200-night trial, double the Otty Hybrid's 100 nights, and both are run by the manufacturer. Both mattresses carry a 10-year guarantee. If you're nervous about buying a mattress unseen, that longer window is a real point in the Eve's favour.
Is the Otty Hybrid better value than the Eve Original?
Yes, on value the Otty Hybrid wins. It sits slightly below the typical price for a hybrid mattress, while the Eve Original sits well above the typical price for an all-foam design. The Eve does offset that with its longer trial and Which? Best Buy status, but pound for pound the Otty gives you more.
Which is better for couples, the Eve Original or the Otty Hybrid?
The Otty Hybrid has the edge for couples. Its 16cm encapsulated pocket springs are designed to minimise motion transfer, so a restless partner disturbs you less, and encapsulation gives firmer edges for sleeping near the side. The Eve is an all-foam design without a stated edge support feature, though its foam feel may suit couples who prefer contouring.
