On aggregated owner reviews the two are level at 4.7 out of 5, so the choice comes down to price, trial and guarantee.

Head to head

Both ranges are sprung throughout, so the difference is in the comfort layers on top and in price. TheraPur runs from soft-medium to extra firm, and Otty runs from medium to extra firm. Otty is the cheaper way in, though not by much. At the top end TheraPur goes further still.

TheraPur

Therapur mattresses have been around for a number of years now as a staple of the Dreams retailers core lineup. Sold exclusively through the retailer, this brand sits at the mid-high end range and commonly features high quality pocket springs as a base layer with gel often accompanying the comfort layer. Ideal for those that want to be kept cool while they sleep, this range of mattresses is mostly praised by owners for comfort and for sleeping cool, though a minority found it hot.

Therapur has a vast array of different mattresses in different tensions helping to ensure that there is something for everyone regardless of how you sleep and your own preference.

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.

TheraPur owner satisfaction

Owner reviews of Therapur mattresses are mostly positive, and comfort is the thing owners praise most. One owner wrote “Absolutely worth the money, so comfortable, cool, amazing quality.” Several mention waking with less back or hip pain. The gel comfort layer sits between the springs and your body, and most owners who mention temperature say it keeps them cool, though a minority found the opposite: one wrote “Not cooling at all,really hot to sleep on”.

The commonest gripe is tension: some owners bought a medium and found it too firm, or firmer at home than the one they tried in the shop. One wrote “Mattress was brought as a medium and is too firm for me and my wife”. A smaller number report a dip forming where they sleep within the first year or two. Therapur mattresses come under Dreams’ 100-night comfort guarantee, which is an exchange between nights 30 and 100 rather than a refund, so a wrong tension can be swapped.

TheraPur durability

Durability remains impressive for the Therapur line up, however, we were disappointed that the entry Polar models carry only a 1 year guarantee where the higher models carry 10 years, particularly given the non-budget price tag associated with the products. That said, many settlement and durability issues that do crop up with all mattresses are often due to a manufacturing defect which will typically appear within that first year of ownership. As such, the one year guarantee on those models, while not ideal, catches the early defects, but not every owner is still covered when a dip appears: one owner of an entry Polar wrote “it is only 14 months old . It is showing signs of dipping where we sleep despite turning the mattress as instructed”.

Beyond the guarantee, durability itself seems to be good provided manufacturer care instructions are adhered to in the form of frequent rotation to ensure adequate and even settlement of fillings and springs. Failure to comply with the rotation guidelines for Therapur products can result in uneven settlement which is best avoided.

Generally, Therapur mattresses are hard wearing and durable with the combination of good quality pocket springs, hard wearing cover and gel comfort layer pairing fantastically to offer ultimate comfort that lasts.

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.

After 10 years with our old OTTY mattress, it was definitely time for a change. I had started waking up with shoulder pain and knew we needed something more supportive, so we visited the store to find the right replacement. The service we received was outstanding. The sales advisor took the time to understand our needs and guided us through the different options without any pressure. I was feeling quite dizzy that day, and her kindness really stood out—she offered me some water and encouraged me to take my time rather than rushing the decision. We eventually chose the Therapur ActiGel Polar 2000 Combination Mattress, and it has been one of the best purchases we've made for our home. From the very first night, it felt incredibly comfortable and supportive. The mattress provides excellent pressure relief for my shoulders while still giving great overall support, and the cooling ActiGel layer helps keep the temperature comfortable throughout the night. We're both sleeping much better, waking up feeling more refreshed, and my shoulder discomfort has improved significantly. The combination of expert advice, excellent customer service, and a fantastic mattress made the whole experience a pleasure from start to finish. I would highly recommend both the Therapur ActiGel Polar 2000 Combination Mattress and the team who helped us choose it. Five stars from us!

I would not give this mattress any stars but the option is not given, we selected this mattress after using the sleep match machine which in Dreams own words (It's a super smart bit of wizardry that chooses the right mattress just for you and the way you sleep. ) this is the most uncomfortable hardest mattress I have ever had I explained to the sales advisor that I suffer with neck and spine problems and could not sleep on a hard mattress she said that the machine recommended a medium mattress we stupidly put our trust in this marvellous machines hands the sales advisor showed us various mattresses from the list that the machine had recommended we chose this mattress and was assured not to worry as we had the 40 days returns policy at no point was it explained that we would have to sleep on the mattress for 30 nights before it could be returned and loose the difference in money if you chose a cheaper mattress. Two days after receiving the new mattress we returned to the store saying I cannot sleep as the mattress is so hard my pressure points are numb and I have pins and needles we were told that the problem is out of there hands and I would need to contact customer services after finally getting through to customer services I was told that they would prefer us to sleep on the mattress for 30 nights to enable the springs to settle down I said when I tried the mattress in the store nobody told us to expect such a difference between the stores mattress and the one we would receive also on our second visit to the store my husband noticed that we had in fact been sold a firm mattress as I am so upset with the service we have received I asked for my money to be refunded I was told this would not happen I would need to choose another mattress and either pay the difference if it was more expensive or loose the money if it was cheaper and also pay for the delivery Please ensure when buying a mattress from Dreams you read all of the small print that you are given once you have made your purchase and also read the reviews on the website as you will see other people have had the same experience as myself, do use the Sleep Match machine as another sales advisor on our second visit to the store said how can a machine tell you what mattress you need I have been selling mattresses for years and do not go by what the machine says.

'Ive been very pleased with the TheraPur ActiGel Polar 2000 Combination Mattress. It offers a really good balance of comfort and support, and the ActiGel layer helps keep the mattress feeling cooler through the night, which has made sleeping much more comfortable. It provides enough cushioning to relieve pressure while still giving good support for my back. The build quality feels excellent, and the mattress has a premium feel. Motion transfer is fairly well controlled too, so movement from the other side of the bed isn't too disruptive. The only reason I'm giving it 4 rather than 5 stars is that it's quite substantial and took a little time to fully break in. It may also feel firmer than expected at first, but it becomes more comfortable after a short period of use. Overall, it's a high-quality mattress that delivers on comfort, support, and cooling, and I'd happily recommend it to anyone looking for a supportive mattress with a cooler sleeping surface.

I tried this mattress a couple of times in the shop, and found it to be comfortable, with a supportive base but soft pillow top that you sunk into, giving a balanced feel. However, when it arrived, it felt considerably firmer than the one that I tried in store, with the pillow top not feeling as thick, and lacking the feeling that you could sink into it. I have had the mattress for 2 months, and in that time it has not felt like it was getting any softer, but I was very disappointed to find that the mattress is developing a not-insignificant sag in the middle (it was being used by a single person), to the point where if you try to sleep at the side, you can sense the slope towards the middle. After just 2 months this is incredibly disappointing, and does not bode well for the long term. In addition, the cooling technology works very well when you are lying directly on the mattress as you do in the shop, but by the time you have added a mattress protector (also by Therapur) and fitted sheet, you can't really notice the cooling benefits any more. Perhaps 1 star is a little unfair, someone who prefers a firmer mattress and is happy for it to be firmer than expected would not be as disappointed, but for me the noticeable dip towards the middle of the mattress is an issue that I could not overlook. I have submitted an exchange under the Comfort Guarantee scheme for a medium-firm Silent Night mattress, as I didn't want to risk the same sagging issues by swapping to a medium firmness mattress from Therapur.

I had the previous version of this mattress—the Polar 800 in a double—which my partner and I loved. We found it comfortable, it helped us stay cool, and we always slept well on it. We wanted the same again, but Dreams had just discontinued it. We decided to buy this newer version and tried it in the shop. It felt a tad firmer, but it was difficult to tell in the shop. Since sleeping on it we can confirm this mattress is simply not a medium. It is like sleeping on the floor, it is so solid. We've kept persevering and even after 6 weeks, it is still so solid. There is no give to it. The is some give in the top layer but the springs are solid. I keep waking in the night with dead limbs. Both my partner, who is now pregnant, and I keep waking up feeling like we've slept on the floor with achy muscles and backs which we never had before. I think this would only start to feel Medium if you were 16 stone plus. Also, the mattress absolutely stunk for the first 2-3 weeks. The chemical smell was so awful it didn't feel suitable for humans to sleep on. We had to leave it to air in our spare room before we could use it. Luckily we kept our old mattress! It's really disappointing and I would not recommend this mattress. It's always such a shame when manufacturers change something for the worse. We are going to exchange it.

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...

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...
