Only Harrison Spinks 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 Harrison Spinks is sprung throughout, with pocket springs or a hybrid build in every model. If you know you want springs under you, that decides it: Harrison Spinks. Harrison Spinks runs from soft-medium to firm, and every Ergoflex mattress is medium-firm. Harrison Spinks covers more of the firmness scale, which helps if two sleepers need different feels. Ergoflex is the cheaper way in, though not by much. At the top end Harrison Spinks goes further still. Ergoflex doesn't have enough owner reviews with us yet to score fairly.

Harrison Spinks

Harrison Spinks is a generational family business that has captured the spirit of the entire hand-made portion of the industry thanks to their traditional materials and handcrafting excellence. The range is of a much higher quality than many competing brands and as a result the price point is typically found within the higher-end but the result is a bespoke nights sleep that will ooze excellence.

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.

Harrison Spinks owner satisfaction

Owners are mostly very happy with this brand which is quite impressive given the price point. Typically we find that when the price of mattresses starts to lead toward the high-end, customers' expectations can sometimes be distorted which results in a less-favourable experience. Thankfully that is mostly not the case here. Owners who bring up the price more often accept it than not, "A bit pricey but the quality reflects the price" as one wrote, though a few didn't think it was worth it, one calling theirs "nothing special for the price I paid". The natural fillings are a reason several give for buying. They can smell at first. That faded within days or weeks for some, but one owner said theirs "smells like a barn". Back pain gets mentioned both ways, with more owners saying theirs has eased than saying the mattress left them aching.

Harrison Spinks supportiveness

The support materials utilised in all Harrison Spinks products is a reliable pocket spring base layer. Pocket springs continue to be the best option for support, offering measured and reliable body contouring across the entire mattress and featuring edge to edge even support and roll together prevention.

Firmness within the range varies but has a pivot toward medium and medium firm tension mattresses all of which are made from luxurious materials and hand made in the UK. Interestingly, Harrison Spinks is the partner of choice for many of the sub-brands sold throughout the popular retailer. The result of this is a Flaxby & Feather and Black sub-division of quality mattresses that will be of equal interest to those looking for a good quality and highly rewarding nights sleep.

Harrison Spinks durability

I think the most important stat when it comes to durability is around the warranty and guarantee periods. After all, if the manufacturer doesn’t believe in their product, why would you? Thankfully you get a 5 year guarantee at minimum across the majority of products on show which comes fairly close to the average replacement period of 7 years for the industry as a whole.

Durability generally doesn’t look to be a concern going by the compounds used. In the reviews, several owners are repeat buyers, one writing “Had a Harrison before and very good for years hence why bought again”, while a small number say theirs softened or dipped within weeks or months.

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.

Owner reviews of Harrison Spinks mattresses

I have had this mattress for 5 weeks now. When I first unpacked it, there was a slight smell for a day, but since then it hasn't smelt at all. (It smelt of canvas which I found quite pleasant actually!) It feels nice and soft each night when you first get on it, but then can feel it supporting you. I guess this is what is meant by a medium-firm mattress. (My old mattress was over 20 yrs old; if anything it would have been rated as very firm!) I have had no problem sleeping with this mattress, no aches or pains when waking up. It is recommended to rotate the mattress once per week for 12 weeks, so I am still doing that. It is easy to do using the handles on the side of the mattress. No depressions in the mattress have appeared, and it still feels just like new. Although we have already had both hot nights and cold ones, I have never felt too hot or cold due to the mattress (obviously the duvet used is also going to make a difference). Overall I am extremely satisfied with the mattress, and with mattressonline.

To be perfectly honest, I'm not convinced but I think the problem is me, not the product. The mattress is clearly very good quality, but it's a lot firmer than I was hoping for and expecting from the soft/medium description. On the spare bed, which is a fully sprung base, it works reasonably well, which is why I haven't yet engaged the 60 day return option, but on the bed I ordered it for originally, which is a solid Ottoman base, it is way too hard. I'm sure that with use it will soften up, but it's still way too hard for me personally to sleep on comfortably and I doubt it will ever be that soft. Indeed, in desperation I ended up going to a shop and buying a much cheaper (and far inferior quality), softer mattress because I simply couldn't do 30 days sleeping on that mattress. I am going to contact Mattress Online today and enquire about swapping it for something softer.

Good Points: Quality is obvious. If we hadn't had a tempur for over ten years, I would say this is a really comfy bed and would be happy for its life time use. Albeit, only five years gauranteed! Having had a tempur though, I would probably revert back. Mainly due to spouse requiring that extra softness and a complete awareness removal from any turn/roll movement by partner. While this is a fantastic make and constructed with the Best Materials, we have been served well with the tempur and too be honest, can say, there aren't any regrets with the purchase. Improvement Points: Comparing this to our tempur, it would be difficult to separate, based on the very different structures. That said, a longer guarantee period would be an advantage. Price for price - this would be a distinct advantage.

We tried the mattress in the shop and picked it over the medium/firm version. However when the mattress was delivered it was so firm it caused my partner hip pain. We contacted mattress inline via the 60 day sleep guarantee and they swapped it next day. The service was 5* and reason we buy all our mattresses via them. The new mattress is the medium firm and is super comfy even after the first night. Makes me think the first was faulty it was that hard and nothing like the shop one we tried.

The mattress smells like a farmyard, not natural, and has made our bedding smell as well as the bedroom. This is not the natural smell the company claims, there is something wrong with the mattress. We cannot have the mattress removed from our home or changed for another month as the company wants to send somebody to check the mattress, but they cannot visit us for the next four weeks. Do not ever buy a mattress from Harrison Spinks unless you enjoy your bedroom and bed linen smelling like you are sleeping in a barn on a farm.
