Simba Hybrid Luxe Mattress Review
A genuinely luxurious mattress that weighs 43 kilograms in a king, which is a practical problem nobody warns you about. The refurbished version at around 849 is the one that makes sense.

Verdict
Thirty-one centimetres, nine layers, up to 5,700 springs across three Aerocoil layers and a bamboo and wool top. It is a genuinely luxurious mattress and it weighs 43 kilograms in a king, which is a practical problem nobody warns you about. The refurbished version at around 849 pounds is the one that makes sense.
Buy it if
You want a premium mattress you can try in John Lewis or Bensons first, and you have help moving it.
Avoid it if
You are buying on value, or you will be handling it alone. Origin's Hybrid Pro gives you more spring at under a third of the price.

The scores
A genuinely premium build let down by a price that assumes you are not comparing.
Origin's Hybrid Pro has more spring and more depth for under a third of this.
Three spring layers over a base is a serious structure. Handles heavier sleepers well.
Bamboo, wool, Simbatex and three spring layers. Among the coolest mattresses sold in the UK.
Deep multi-layer spring construction holds the perimeter well.
Three layers of independently pocketed conical springs. Excellent for couples.
200 nights and 10 years, with a returns process that functions at scale.
Forty-three kilograms, and why that matters
A king size Hybrid Luxe weighs around 43 kilograms. That is heavier than most washing machines and it is the single most practical thing about this mattress that nobody mentions.
Three consequences follow. Rotating it, which Simba recommends monthly for the first three months and then quarterly, is genuinely a two-person job. Getting it up a narrow Victorian staircase in its box is difficult. And if you live alone, changing a fitted sheet on a 43 kg, 31 cm mattress is considerably harder than the same job on a 25 cm one.
None of that makes it a bad mattress. It means you should think about your stairs, your bed frame and whether you have help before ordering, and nobody selling it will raise any of it.
Check your bed frame will take the load, too. A 43 kg mattress plus two adults is a meaningful load on slats designed for a 20 kg foam mattress.
What nine layers actually buys you
Simba's Luxe stacks three separate Aerocoil micro-spring layers, which is where the 5,700 figure comes from. Each is 25 mm, conical, titanium alloy, and pocketed.
Stacking conical springs has a real effect that is worth understanding. Because they are conical, each spring can collapse into the one below, so a stack of three behaves closer to a single taller spring than three short ones in series. That gives you more travel and more progressive support than a single micro-spring layer can.
It is a clever solution to a problem Simba created by putting the springs at the top. A traditional pocket sprung mattress simply uses taller springs, which is why Otty gets similar structural behaviour from 2,000 springs at 16 cm that Simba needs 5,700 at 25 mm to approach.
The bamboo and wool top layer is the other genuine upgrade, and wool in particular does real work on moisture regulation across seasons rather than simply feeling nice.
Buy the refurbished one
Simba lists refurbished Hybrid Luxes at around 849 pounds against 1,249 new. That is a 400 pound saving on a mattress that has been inspected and re-covered.
At 1,249 I struggle to recommend this over an Origin Hybrid Pro at 374. At 849 the conversation changes, because you are buying premium construction, a brand with a functioning returns operation, and a mattress you can go and lie on in John Lewis first.
Before buying refurbished from anyone, establish whether the trial and the guarantee still apply. If they do not, you are buying a mattress you cannot send back, and on a 31 cm, 43 kg mattress that is a bigger commitment than usual.
Should you buy it?
At 849 refurbished, yes, and it is one of the better premium purchases available. At 1,249 new, only if the ability to try it in a shop and the confidence of a large brand genuinely matter to you, because on construction alone it does not win.
If your budget is around 1,250 and you want the most mattress, look at the Hybrid Ultra refurbished instead, which lists at around 699 and is a bigger build than this.

Questions people ask
How heavy is the Simba Hybrid Luxe?
Around 43kg in a king size, which is heavier than most washing machines. Rotating it is a two-person job, getting it up a narrow staircase is difficult, and you should check your bed frame slats will take 43kg plus two adults.
Why does the Simba Luxe have three spring layers?
Because Aerocoils are only 25mm tall. Conical springs collapse into the one below, so a stack of three behaves closer to a single taller spring. It is a clever solution to a problem Simba created by putting the springs at the top of the mattress.
Is the refurbished Simba Luxe worth it?
At around 849 pounds against 1,249 new, yes. You are buying premium construction from a brand with a functioning returns operation and a mattress you can try in John Lewis first. Confirm whether the trial and guarantee still apply before ordering.
