The Simba Hybrid Mattress and the Nectar Memory Foam Mattress are two of the UK's most searched-for beds, and this comparison settles which one deserves your money.
You've narrowed it down to two very different builds. The Simba Hybrid is a five-layer design combining up to 1,900 Aerocoil microsprings with graphite-infused Simbatex foam, which means a springier, more responsive feel with built-in heat management. The Nectar is all foam: three layers of CertiPUR certified foam beneath a cooling cover, giving you that classic contouring hug where you sleep slightly in the mattress rather than on it.
Both are 25cm deep, both rated medium-firm, both backed by a 10 year guarantee. The Nectar wins this comparison. It sits well below the typical price for a memory foam mattress, while the Simba sits noticeably above the norm for a hybrid, and that value gap is hard to argue with when the depth, firmness and guarantee all line up so closely.
That said, the Simba has real strengths, particularly if you dislike the enveloping feel of foam or need a wider choice of sizes. Here's how the two compare in detail.
Our verdict at a glance: which mattress wins?
The Nectar delivers a comparable depth, firmness and guarantee for meaningfully less money, sitting well below the typical price for its construction where the Simba sits well above.
WINNER
You want spring-backed responsiveness
The 1,900 conical Aerocoil microsprings compress individually to your body, which means support that pushes back rather than the sink-in hug of all-foam designs, plus limited motion transfer for couples.
You need a wider size range
Simba offers the Hybrid in 8 sizes against Nectar's 5, so awkward bed frames and non-standard rooms are easier to accommodate.
Zoned support matters to you
The nine-zone CertiPUR foam base firms up under hips and shoulders, which means heavier areas get targeted support rather than a uniform surface.
RUNNER UP
You want better value
The Nectar sits well below the typical price for a memory foam mattress, where the Simba sits comfortably above the median for a hybrid, so you keep more of your budget for the same depth and guarantee length.
You want a full year to decide
Nectar's 365 night manufacturer trial gives you every season to test it, which is longer than most brands manage.
You sleep hot through menopause
The cover carries MTick certification for menopause-friendly cooling, and the open-cell foam encourages airflow, which means the classic memory foam hug without quite as much heat retention as older foam designs.

On build quality alone there's little to separate them. Both are 25cm deep with five layers, and both use CertiPUR certified foam. The real difference is character: the Simba's microsprings give a responsive, pushed-back feel, while the Nectar's memory foam contours slowly around you. Pick by feel preference rather than by quality here.

Which mattress feels better?
<p>Both mattresses are rated medium-firm, with Nectar putting a number on it at 6.5 out of 10. In practice that puts the Nectar in territory that suits most back and combination sleepers, and its pressure-relieving memory foam eases hips and shoulders for side sleepers too. The Simba's feel comes from springs rather than foam alone, so it sits slightly on the supportive side. Across owner reviews, the most common Simba adjustment note is that it can feel firmer than expected in the first few weeks.</p><p>Neither is ideal for everyone. Tom's Guide found the Simba less suited to committed front sleepers and possibly a little firm for lighter-weight people. The Nectar, for its part, will feel too enveloping if you love the springy feel of a traditional pocket sprung bed, and a little solid if you want a very soft, sink-in surface.</p>
Other important factors to consider before buying.
Beyond feel and price, the safety net matters: how long you get to test the mattress at home and what the guarantee covers. Both brands are generous here, though the details differ. The table below sets out the trial and guarantee terms side by side.

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.

Prices for both change often, so check the live tables below. Broadly, the Nectar comes in lower like for like, and sits below the typical price for its construction type where the Simba sits above.
Simba Hybrid Mattress
The Nectar Memory Foam Mattress is the winner here, and value is the reason. It sits well below the typical price for a memory foam mattress, while the Simba Hybrid sits around a third above the median for a hybrid, yet both give you 25cm of depth, a medium-firm feel and a 10 year guarantee. The Nectar also carries the stronger certification list, including MTick for menopause-friendly cooling. The Simba fights back on choice, with 8 sizes to Nectar's 5, and its microsprings will suit anyone who finds memory foam too enveloping. But for most buyers weighing these two, the Nectar delivers a comparable specification for meaningfully less money, and its 365 night trial gives you a full year to confirm the decision at home.
Decision helper
Consider your primary need: the responsive, spring-backed feel and wider size range of the Simba, versus the contouring comfort and stronger value of the Nectar.

Is the Simba Hybrid or Nectar mattress better?
The Nectar wins on balance, mainly on value: it sits well below the typical price for a memory foam mattress while the Simba sits above the norm for a hybrid, with both offering 25cm of depth and a 10 year guarantee. The Simba is the better pick if you prefer a springier feel or need one of its 8 sizes.
Which is firmer, Simba Hybrid or Nectar?
They're closely matched: both are rated medium-firm, with Nectar specifying 6.5 out of 10. The Simba may feel slightly firmer in practice, as owner reviews commonly mention it feeling firmer than expected in the first few weeks, and Tom's Guide noted lighter-weight sleepers may find it a little too firm.
Does the Nectar mattress sleep hot compared to the Simba?
Both take cooling seriously. The Nectar uses open-cell foam and a cover with MTick certification for menopause-friendly cooling, while the Simba pairs graphite-infused Simbatex foam with airflow-promoting open-structure layers. Hybrids and foams handle heat differently, but on stated cooling materials there's little between these two.
Which has the better trial, Simba or Nectar?
Nectar offers a 365 night manufacturer trial, a full year to decide at home. Simba's held details mention a 200 night trial on every size. Both brands back their mattresses with a 10 year guarantee, so the terms are generous either way, with Nectar edging ahead on trial length.
Is the Simba Hybrid worth the extra money over the Nectar?
Only if the hybrid feel matters to you. The Simba's 1,900 microsprings give a responsive, pushed-back feel with good motion isolation, and it comes in 8 sizes to Nectar's 5. If you're happy with a contouring memory foam feel, the Nectar offers comparable depth, firmness and guarantee for meaningfully less.
