Otty Review: Every Model, Scored
The best mattress brand in Britain on construction per pound, and the reason is one decision nobody else made.

Verdict
The best mattress brand in Britain on construction per pound, and the reason is one decision nobody else made. Otty's springs are 16 centimetres tall. Simba's Aerocoils are 25 millimetres. One of those is a support core and the other is a comfort layer, and that difference runs through everything.
Who should buy it
You want the most spring structure per pound available in the UK, and a firm feel suits you.
Who should avoid it
You want soft. Otty runs firm across the range, and only the Pure+ 4000 sits below 7 out of 10.

The Blue Light Card rate is standing rather than seasonal and often beats the sale price.

Scores are mine, using the six criteria set out on the method page. Prices are the lowest UK size before discount and move constantly.
Sixteen centimetres against twenty-five millimetres
The single fact that explains this brand
Otty's pocket springs are 16 centimetres tall. Simba's Aerocoil micro-springs are 25 millimetres.
A 16 centimetre spring layer is a support core: it holds your spine up. A 25 millimetre spring sits in the comfort layers and improves surface responsiveness and airflow. Both are springs. They do different jobs.
This is why spring counts across brands are not comparable, and why I keep saying it. A Simba Hybrid Pro lists up to 4,800 springs and an Otty Original lists up to 2,000, and the Otty has considerably more structural spring in it.
When you compare mattresses, ask two questions about the springs: how tall are they, and where in the mattress do they sit. The headline count on its own tells you very little.
Where Otty's value actually sits
Read the range table above from top to bottom and a clear pattern emerges.
Between £500 and £600, each step buys meaningfully more construction. The Original gives you the 16 centimetre core, the Pure Pro adds 1,000 springs, the Pure+ 4000 adds another 1,000 and drops to a soft 5 out of 10.
Above £840, each step buys materials while the spring engineering stays broadly constant. The Natural Origin and Natural Evolve are good mattresses and they do not give you a better spring unit than the Pure Pro at £540.
So the question to ask yourself is not which Otty is best, it is do I want more mattress or different materials. Below £600 you are buying the first. Above £840 you are buying the second.
The three highest scores in the range all sit between £500 and £600, which is unusual and worth noticing.
Otty runs firm, and you need to plan for that
Almost every Otty sits at 7 out of 10 or above. The Extra Firm is a 9, the Natural Origin an 8, and most of the rest are 7.
The exception is the Pure+ Hybrid 4000 at a stated 5 out of 10, and it is built correctly for that: 4,000 springs beneath a soft surface. A soft mattress needs a high spring count, because when you sink the mattress must form around your shape and each region has to respond independently. A soft mattress with a low spring count is a hammock waiting to happen.
So if you want soft from Otty, the Pure+ 4000 is the only real answer, and it is a good one.
The firmness ratings are not reliable
Otty rates the Pure Hybrid at 6.5 out of 10. Tom's Guide tested the same mattress at 8.5. That is a two point gap on a ten point scale between the manufacturer and an independent tester, and it is why I treat published firmness ratings as a guide within a range rather than a measurement.
The Blue Light Card rate is the real discount
Otty's standing Blue Light Card rate frequently beats whatever sale is running, and unlike a seasonal promotion it does not expire.
If you or anyone in your household is eligible, check that rate before anything else. It is the least publicised and most reliable saving in this brand's pricing, and it applies across the range rather than to selected models.
Which Otty should you buy?
The Pure Pro Hybrid at £539.99 is the best mattress in the range and the highest score on this site outside Origin. Up to 3,000 springs on Otty's tall spring architecture.
The Original at £499.99 if budget is tighter. It is the mattress that defines the brand and it is excellent.
The Pure+ 4000 at £599.99 if you want a softer feel, and it is the only Otty that delivers one properly.
The Extra Firm if you are heavier or have been advised to sleep firm. It and Rem-Fit's 4000 Ortho Elite are the two UK options I would actually recommend in that category.
Not the natural models unless the materials specifically matter to you, because you are paying £300 to £400 more for fillings rather than structure.
A correction worth making
Commonly repeated, and wrong
Spring counts are compared across mattress brands as though the numbers describe the same thing, and they do not. Otty's pocket springs are 16 centimetres tall and form the support core. Simba's Aerocoil micro-springs are 25 millimetres and sit in the comfort layers above a separate base. A mattress listing 4,800 springs can contain far less structural spring than one listing 2,000. Compare spring height and position, not the headline figure.
Should you buy from Otty?
Yes. On construction per pound Otty is the strongest mainstream brand in Britain, and the 16 centimetre spring core is a genuine engineering difference rather than a marketing one.
Buy between £500 and £600, check the Blue Light Card rate first, and take the Pure+ 4000 if you want soft. Only Origin beats it on price for comparable construction, and Origin has a much shorter UK trading history.

Questions people ask
Which Otty mattress is best?
The Pure Pro Hybrid at 539.99, with up to 3,000 springs on Otty's tall spring architecture. The Original at 499.99 if budget is tighter, and the Pure+ 4000 at 599.99 if you want a softer feel, which is the only Otty that delivers one properly.
Why are Otty springs different?
They are 16 centimetres tall and form the support core. Simba's Aerocoil micro-springs are 25 millimetres and sit in the comfort layers. Both are springs doing different jobs, which is why spring counts across brands are not comparable.
Is Otty good value?
Between 500 and 600 pounds, exceptionally. Each step in that band buys meaningfully more construction. Above 840 pounds each step buys materials while the spring engineering stays broadly constant, so the natural models cost more without supporting you better.
Does Otty do a Blue Light Card discount?
Yes, and it is a standing rate rather than a seasonal promotion, so it frequently beats whatever sale is running and does not expire. It applies across the range rather than to selected models.
