Only Otty has enough owner reviews to score, so there is no head-to-head verdict here.

Head to head

Ergoflex is all foam, with no springs anywhere in the range, while Otty is sprung throughout, with pocket springs or a hybrid build in every model. If you know you want springs under you, that decides it: Otty. Otty runs from medium to extra firm, and every Ergoflex mattress is medium-firm. Otty covers more of the firmness scale, which helps if two sleepers need different feels. Both start at much the same price. But at the top end Otty goes further, so it also has the more premium options. Ergoflex doesn't have enough owner reviews with us yet to score fairly.

Otty

Otty is a British brand that started in 2016 and has grown quickly into one of the most recognised hybrid mattress names on the UK market. The company is based in Leeds and sells direct to the customer, cutting out the middle man in the traditional bed retail chain and passing the savings on in the form of long trial periods and sensible prices.

Their hybrid lineup pairs cooling gel infused memory foam with individually encased pocket springs, and it is the hybrid build that Otty is best known for. Most mattresses ship vacuum packed in a box, and buyers get a 100 night home trial along with a 10 year guarantee.

Ergoflex

Ergoflex entered the UK in 2006 and is one of the original bed-in-a-box brands, predating Emma, Simba and Nectar by nearly a decade. The brand has stayed true to a single-product philosophy throughout, with the Ergoflex 5G being the current and only mattress in the range. It is a deep, five-layer all-foam mattress measuring about 23 cm, built entirely from Ergoflex's own in-house manufactured foams and wrapped in a removable TENCEL cover.

The single-product approach is deliberate. Rather than splitting engineering effort across a dozen models, Ergoflex invests all of its development into refining the 5G. The result is a mattress that has been steadily improved over multiple generations without the complexity of a large catalogue.

Otty owner satisfaction

Plenty of owners write about support, often with a bad back behind the purchase. "Back ache stopped immediately", one wrote, and another found it "firm but really supportive" and "Great for my bad back." Couples mostly say partner movement barely registers: "I never get disturbed by my wife when she moves around anymore".

Complaints about the mattress itself mostly come down to firmness. Some owners found it harder than they bargained for ("it is very very firm" and "It seems firmer than I expected"), and the hot-sleeper verdict splits, from "as a hot sleeper I find it very breathable" to "I’ve felt rather hot during the night." Edge support splits the same way: one owner wrote "Decent edge support too, much better than of the Emma one." while another's husband "feels like he’s rolling towards the edge of it." Many owners praise a fast delivery, but the sharpest gripes are about couriers rather than the mattress. One owner had the pick-up and delivery go out of sync twice. Another wrote that "Otty had delivery problems with their previous couriers who did not deliver" and still called the customer service "excellent".

Otty supportiveness

The Otty Original Hybrid uses a top layer of cooling gel memory foam over a reflex foam transition layer and a core of pocket springs. Each spring moves independently, which is why the mattress copes well with two people of different weights sleeping side by side. The foam layers add enough pressure relief for the shoulders and hips, and the spring core keeps the lower back properly supported without letting anyone sink into a hammock shape.

For heavier sleepers over about 15 stone, Otty makes the Firm Hybrid, a flippable mattress rated 9/10 for firmness on one side and 10/10 on the other. Support comes up again and again in the reviews. One owner wrote: "I feel much better supported at hips and shoulders when I'm sleeping".

Otty durability

Otty uses a high gauge spring unit and good quality foams above it, which is the right recipe for a mattress that holds its shape over the long run. Most Otty covers are removable, and several are machine washable, which is unusual at this level of the market and helps the mattress stay fresh over the years.

Owners split on how it wears. One owner about two years in reported "absolutely no signs of sagging", while another found theirs "already dipping in the middle" after eighteen months. The 10 year guarantee gives a clear signal of how much life the brand expects out of its own product. Given the materials and the build, Otty mattresses are well positioned to last the seven to ten years that most buyers are looking for.

Otty best offers

We've managed to find the following top deals from across the web on Otty mattresses.

Ergoflex owner satisfaction

Ergoflex carries OEKO-TEX certification on its materials and a 10-year guarantee as standard. The 30-night trial is shorter than most current rivals, with Emma and Simba at 200 nights and Nectar at 365, but it is enough time to form a proper opinion on the feel.

The single-product model removes the decision fatigue that affects buyers shopping brands with large catalogues. There is one mattress, one feel, one price. That simplicity is a genuine selling point for buyers who find the mattress market overwhelming.

Ergoflex supportiveness

The 5G uses a 9 cm high-density visco-elastic comfort layer for pressure relief, a 5 cm cool-sleep airflow system for temperature management, and a 9 cm resilient base for structural support. The overall feel is medium firm and the foam contours to the body progressively rather than sinking in immediately. Back sleepers and side sleepers of average weight are well served.

The deep all-foam build means the 5G does not have the bounce or responsiveness of a hybrid pocket spring mattress. Stomach sleepers and restless sleepers who change position frequently during the night may find the slower foam response restrictive compared with a spring-based alternative.

Ergoflex durability

In-house foam manufacturing is the single biggest advantage Ergoflex has on durability. Because the brand makes its own foams rather than buying from third-party suppliers, the density and quality of the raw material is controlled from production through to finished mattress.

The 10-year guarantee backs the build quality, and the removable TENCEL cover helps with long-term hygiene by allowing the outer layer to be washed independently of the foam core. For an all-foam mattress at this price tier, the durability profile is strong.

A great mattress. We looked at several of the leading hybrid mattresses on the market, and after a discussion with the sales person via chat on the website (as it was during lockdown), they were able to answer many of my questions clearly and exactly why Otty Mattress is a better product than its competitors. The delivery service and also the ease of ordering the product was great and most importantly we have had fantastic nights sleep since purchasing this mattress. Fantastic product and you wi...

Absolutely love my new mattress, I ordered the hybrid mattress and I have not been disappointed, the website was so easy and the payment plan was a dream, delivery was extremely quick even with all the delays due to the Coronavirus I ordered sunday and my mattress was delivered Wednesday morning, it was so easy to open and within 4 hours it was fully inflated. I could not recommend it more, it is so comfortable its alot firmer then my last memory form mattress which is what I wanted. The depth o...

Absolutely love my Otty matress, I went for the hybrid and I was not disappointed. I was hit by a car whilst pregnant and broke my tibia platueu so have since suffered with problems in both knees and my back so it was important to get a good nights sleep and rest well. The Otty matress has given me just that and my 18 month old son loves snoozing ontop of their pillows too. They offer a 100 day money back guarantee which I think is great, although personally I'd be pretty surprised if anyone wan...

Appalling customer service. Wasted a days annual leave waiting for my mattress, it arrived the following day. There was no communication and when I questioned it I was told that I was rude and they couldn?t do anything to help. I paid extra to have the mattress delivered to the room of my choice . On delivery the men refused to take it upstairs due to health and safety regulations. Again when I mentioned this to otty customer services they weren?t interested. Eventually I was told by the boss Da...

Bought two mattresses for two different bedrooms; one original hybrid and one aura hybrid mattress. Although advertised as levels of 7 and 6 firmness respectively, they are much firmer than expected; you barely sink into them! The aura hybrid was used by my partner and I (15 and 11 stone) and we still found it very firm that it gave us lower back pain. We trialed them for 6 weeks before giving up on them and when we tried to claim the 100-night trial that each mattress advertised, it turns out w...
