Becky’s take

By Becky Reeve

Checked against current models and prices in October 2026

If money is tight, buy the SleepSoul, because its Heaven 1000 Pocket Gel is the same idea as a Therapur for far less. It is gel foam on pocket springs, medium, rolled into a box. SleepSoul is Birlea's boxed brand and Mattress Online sells it. The Heaven and the Balance 800 are both medium with a plain top.

Therapur gives you two things SleepSoul can't. The first is a choice of tension. SleepSoul's plain-topped models are medium or firm, while Therapur starts at soft-medium and goes all the way to extra-firm, so there is something for heavy and light sleepers alike. The second is a Dreams shop where you can lie on it first.

Whatever you spend, leave SleepSoul's pillow-tops alone, which is most of the range. The pillow-top versions of the Cloud, the Luna and the Space all have the soft layer sewn on, so you can't turn the mattress over once it sinks. For a first flat, a spare room or a tight month, buy the Heaven 1000. For the bed you'll sleep on for years, buy the Therapur in the sale.

Head to head

TheraPur has sprung throughout, every model a hybrid; SleepSoul has 10 of its 11 mattresses sprung. TheraPur runs from soft-medium to extra firm, and SleepSoul runs from soft-medium to firm. SleepSoul is the budget choice of the two: TheraPur's cheapest mattress costs several times as 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.

SleepSoul

SleepSoul is one of the newest manufacturers to make a splash in the last few years, entering the arena at the start of the first lockdown and rapidly expanding through its use of existing supply chains provided by its parent company, Birlea. Since inception SleepSoul has rapidly gained a strong market position in the bed in the box space, competing directly with other popular manufacturers like Eve, Simba and Nectar.

SleepSoul are not sold directly and are instead sold through a host of retailers up and down the country in both online and offline capacity where the price of these mid-tier priced products tend to get carved up down to the lowest pound as everyone reaches to capture the sale.

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.

SleepSoul owner satisfaction

Owners are mostly happy with the SleepSoul range, and the praise is much the same across it: comfort, value and a box that is easy to unpack. One Bliss 800 owner called it “Good quality and excellent for the price”. Another found it “very easy to manage, open and soon plumped up”.

Firmness is the recurring complaint, and it runs both ways on the same model: one Bliss 800 owner wrote that it was “not medium as advertised. It's soft.” Another found the same mattress “Far more firm than the description suggests”. A few owners find them warm at night. The other complaint that keeps coming up is edge support, mostly on the Comfort 800 and Heaven 1000, and a few owners across the range say they can feel the springs. One Comfort 800 owner wrote that “the unsupported edges are annoying”.

SleepSoul supportiveness

Supportiveness is at the forefront of SleepSoul design, with pocket spring support structure taking centre position in the lineup and offering a great variety of tensions ranging from medium to firm in their more popular offerings. The open coil variants perform less well however, do feature at a price point making them a great option for those on a budget,

The support layer in much of the range is able to be compacted and rolled, giving you a tighter package come delivery that saves on logistical and delivery costs that can be passed on to you.

SleepSoul durability

Owner reviews of the range go back years, and those that mention wear are split. One owner bought a second SleepSoul about five years after the first and said the original was “STILL as good and cosy as new”. A small number report a dip or sag forming within the first few months.

To offset this concern, SleepSoul has developed a 10 year warranty to accompany the purchase of mattresses in the range. This warranty should go a considerable way to alleviating the worry over sagging and will help establish SleepSoul as a leader in the industry.

Owner reviews of TheraPur mattresses

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.

This is a really comfortable, good quality mattress. When it arrived (in an amazingly small box), the mattress was well wrapped up in plastic and there was a little tool to slice the plastic open without slicing the mattress, plus instructions for the mattress. It was simple and straightforward and the mattress was ready to sleep on in just an hour or so. There was no obvious chemical smell, just a slight whiff if I put my nose right on it as soon as it came out of the wrapping. I haven't been bothered by any smell when sleeping on it. I bought it as an urgent need because the old one was giving me back pain. After two nights on this mattress, the pain was gone and i've had a couple of weeks of very comfortable nights with much better sleep so far. The only thing i'm not so pleased with is the edges squish down when you sit on them. I guess they have to in order to fit inside the small box but I prefer the edge of a mattress to keep its shape when I sit on it. It's not a major problem as I sleep alone but if I shared it and had to sleep near the edge, i'd feel as if I was going to roll out of bed. I'd want a king size if I was to share it. I will also get a mattress topper just to increase the comfort factor even more (and to fulfil the conditions of the guarantee). Overall, I am very happy with this mattress, it's great to feel comfortable and well supported. With the discount, it's amazing quality for the price. So glad I bought it; my back thanks me every morning.

Good Points: It's the first new mattress I have had in years and its quite a difference but theres lots I like about the change: - The mattress is very supportive of my body, I'm 5'11 and weigh nearly 100kg's, support matters! - It feels stable and doesn't make me roll to any low spots - The mattress is far lighter than I anticipated so rotation by myself is really easy, especially with the handles - It keeps me warmer which during the late heat was a bit of an issue but I think I'll appreciate it during the winter - It arrived rolled and it was easy to remove and set up in no time Improvement Points: There are a couple of things but these are very minor, and they are just my views: - The handles, despite the low overall mattress weight dont feel very sturdy and I worry I'll rip them clean off - The measurements indicate the mattress depth, and was made very clear on the website, but depite my measurements it was still a shock to see such a deep mattress having been used to very thin one for years - I think I remember seeing it mentioned as being on the firmer side of things but compared to my previous mattress this is much softer (not necessarily a bad thing, just didnt expect it is all) Thats it really. As you can see the negatives for me are very minor and I would overall highly recommend the product.

The product itself is as expected, it was delivered vacuum packed in a box as tall as the mattress is wide and rolled up, so it doesn't take up too much space and is just small enough for the average male to handle. It is of cause a bit on the heavy side so probably be a good idea to get help if moving up stairs but is easy enough to slide up the stairs on its side. The box contains the mattress along with a handy safety knife to open the vacuum sealed bag and some documents. After removing the mattress from the box take care with the unrolling as it is a bit weighty and king of suddenly springs/flops the last 2 or 3 foot so have no breakables near the end if unrolling on the bead frame. When cutting the plastic try not to cut a large hole, doing this will allow the air to gradually enter the mattress and the mattress will safely spring back to it intended shape, then you can remove the plastic with the provided safety knife. The mattress boasts a 1000 pocket springs topped with memory foam so no need for a mattress topper as there's plenty of padding on top of the springs. I found the medium firmness of the mattress to be just right for me and after having the mattress for a month now I can confirm that I sleep better. The price was very competitive the quality it right for the price but the delivery let down experience a bit, the guy was unbelievably miserable didn't say a word to me, didn't smile (giving off couldn't care any less vibes) attitude was disgusting.

Improvement Points: I ordered the 120cm wide 'small double' mattress. Once unwrapped, it was clearly far too wide and would not fit on my bed frame, being around 125 cm wide. I know that foam mattresses take a while to regain their proper shape, however this has not been as quick as anticipated. As a the spare bed mattress, it has slowly change shape, and after about 4 weeks of resting and not being slept on, it is now about 122cm wide. It just about fits onto the frame.

1 Trusted Customer

Good Points: In the first year or so resonably comfortable but then it goes wrong... Improvement Points: After about 2 years the mattress has developed 2 distinct dips, about 3cm deep (after ~4 hours after getting about of bed. They are worse first thing) so at night you keep rolling back into them. I'm told : 'Over a period of time the body will create a natural impression on the mattress. This is known as settlement and is perfectly normal.' I dont beleive a dip that is deep enough to affect your sleeping position is normal and i didn't have this in a previous memory foam mattress. We only changed as we went up in bed size. So after 2 years use of a mattress that has a 10 year warranty I am having to buy a new one as this is unbearable to sleep on. Spend a bit more and get something better with reviews after a few years, not a few days.
