There’s plenty of choice if you want a Rest Assured mattress.
They’re a big name in the UK mattress market and they’ve been going for more than a century.
I’d describe a Rest Assured mattress as a mid-priced choice. They’re owned by the same company as Silentnight and they’re (very) roughly in the same price bracket. Rest Assured specialise in traditionally made mattresses which use springs, whereas Silentnight also make a lot of foam and hybrid mattresses.
Rest Assured make their mattresses in the UK (in Lancashire to be precise).
We’ve picked out five of the best Rest Assured mattresses you can buy, taking into consideration value for money, specification, thousands of customer reviews and industry awards. We’ve tried to include a mix of softer, firmer and medium tension Rest Assured mattresses and a range of prices.
Prices mentioned relate to double mattress prices and are correct at the time of typing in 2024.
Pros and cons of a Rest Assured mattress
Pros
- Longer established than popular foam brands such as Simba Sleep and Emma Mattress
- More affordable than posh pocket sprung brands such as Vispring and Hypnos
- Widely available, making in store testing possible
- Big range and plenty of choices of firmness levels and prices
- Traditional construction methods will suit a lot of people (e.g. less of a chemical smell than with new foam mattresses)
- Made in the UK
- Awards from Good Housekeeping
Cons
- Warranty lengths tend to be shorter than similarly priced ‘bed in a box’ mattresses
- Trial periods (where available) offer a swap rather than a refund and don’t last as long as some other brands.
- Several models are single sided
1. Rest Assured Venice 1400 Pocket Ortho Mattress – £370 – firm
The Venice 1400 is one of Rest Assured’s cheaper mattresses but you get a solid mattress for your money. It’s not as posh or luxurious as the Rest Assured British Wool 2000 mattress (see #2) but it’s about half the price.
The ‘1400 pocket’ bit mentioned in the title refers to the type of springs used in the mattress and the number of springs. Decent sprung mattresses like this one use ‘pocket springs’ whilst cheaper and wobblier sprung mattresses use ‘open coil’ springs. There’s no real debate on this one – pocket springs are far better and are worth the upgrade if you can afford it.
1400 is the number of springs that you get on the king size version of this mattress. There is an argument that very heavy people benefit from a number nearer to 2000 springs, but 1400 will offer a good level of support for the vast majority of people.
(As an aside, you’ll find that most pocket sprung mattresses are between 1000 and 2000 springs. If it’s less than 1000 then the level of support isn’t so great. If a mattress claims to have thousands of springs then they actually mean that there are multiple layers of springs and lots of them will be very small so are mostly to add a bit of comfort.)
The Venice 1400 is a good depth at 26cm. Depth is no guarantee of quality, but most decent mattresses are somewhere between 20cm and 30cm deep. Thinner mattresses tend to be cheaper.
The downsides with this Rest Assured mattress
On the downside, this mattress only comes with a 5 year guarantee. That’s reasonable for the price tag but you’ll find a lot of modern ‘bed in a box’ mattresses which are made from foam offer 10 year guarantees or even ‘forever’ guarantees for a not a great deal more money (e.g. Nectar Sleep). Many of them also have no-risk trial periods, where you can get a refund if you don’t like it. You don’t get that with this mattress.
Another thing to be aware of is that this Rest Assured mattress is single sided. That means you can’t flip it over to help extend its life. You can turn it round but that isn’t quite so effective in stopping a mattress getting a bottom-shaped indent over time.
Customer review scores are currently about 4.9/5.
The Rest Assured Venice comes in the standard mattress sizes of single, small double, double, king size and super king size.
2. Rest Assured British Wool 2000 Pocket – £729 – softer or firmer versions
The Rest Assured British Wool 2000 mattress is certainly a jump up in price but you do get some notable upgrades.
Most importantly, you can choose from softer or firmer versions of the same mattress.
Firmness is a tricky thing to get right with a mattress, particularly if you’re buying online. The mattress industry has never quite agreed on what it means when a mattress is ‘soft’ or ‘firm’ so there’s a risk that a ‘firm’ mattress by Rest Assured will feel slightly different to a ‘firm’ mattress by Hypnos or Dormeo, for example.
However, there are a couple of general rules to help you get the right firmness:
- if you’re heavier than average then you will need a firmer mattress than someone who is lighter than average. Heavier people sink into a mattress more and probably won’t end up in a good sleeping position on a very soft mattress.
- if you mostly sleep on your side then your hips and shoulders are under more pressure during the night than someone who sleeps on their back or front. So, the usual guidance is that side sleepers need slightly softer mattresses to avoid waking up with a sore shoulder and hips.
The idea is that you take those two things into account and then decide which firmness level is right for you.
Other notable upgrades with this mattress
You’ll have twigged that this mattress is twice the price of some of the other Rest Assured mattresses. For the extra money, you are getting:
- three layers of wool rather than cheaper materials such as polyester or recycled fibres. Wool is naturally good at regulating your temperature (when did you last hear a sheep complaining?). The multiple layers does make this mattress huge at 37cm deep so you will need extra deep sheets.
- the option to flip the mattress over because it is double sided. That should help a mattress last longer, assuming you are strong enough to lift it.
- a high spring count. This is not a major deal if you are a normal sized person but if you’re much heavier than average then you’ll get some benefit from 2000 springs compared to 1400. In this case, the mattresses are spread over two layers rather than one layer.
It’s also a popular mattress with customers (4.8/5 from reviewers) and with experts (Good Housekeeping Institute Approval).
On the downside, you still only get a 5 year guarantee despite the higher price. It will also weigh a huge amount in king size and super king size, so you might struggle to turn it over without the help of the local tug-of-war team. It’s worth saying again that this mattress is exceptionally deep! Shorter people might need a run up!
This Rest Assured mattress is more expensive but it’s made with natural materials
3. Rest Assured Knowlton 2000 Pocket Latex Pillow Top Mattress – £625 – medium firmness
Our next pick in our list of the best Rest Assured mattresses in the UK is the Knowlton 2000, which uses a combination of springs and latex. It’s a medium tension mattress.
It’s got a high number of springs on the bottom, which will be enough to support you even if you are on the larger side. On top there’s a layer of latex, which is a natural material from rubber trees that is particularly good for mattresses. Mattress Online reckon that ‘latex responds to your weight and shape to provide pressure relief tailored to you’.
Is latex a good material for mattresses?
Scientific studies have looked at the impact of different mattress materials for sleepers. Oz, Merav et al studied the ‘volatile organic compound emissions’ on foam mattresses and found that ‘Under sleeping conditions VOC emissions increased significantly’ (2019). Meanwhile, natural latex will ‘produce lower levels of gases’ according to WebMD. Of course, this mattress isn’t 100% latex, but it is the part of the mattress that you will be closest to when sleeping.
Latex is an expensive material, so you only actually get a 2.5cm layer on top (that’s about an inch, Grandad). Customers rave about it though and give it a score of 4.6/5 at the time of writing. If you want a mattress with a much deeper layer of latex then you’ll have to pay £1000+ (see our latex mattress guide, if you’ve not lost interest already).
What about the pillowtop?
The downside of a mattress with a ‘pillowtop’ (i.e. a layer of a different material on top) is that you can’t turn it over. That’s because the pillowtop is only on one side of the mattress.
As with several other Rest Assured mattresses, this one has approval from the Good Housekeeping Institute. Reviews are excellent and there are plenty to go on.
One piece of good news is that you get a comfort trial period with this mattress via Mattress Online. A few years ago, trial periods were unusual with mattresses but they have become much more common. You can swap it for another mattress within 60 days if you don’t like it. Have a read of the terms and conditions first. One key detail is that you need to try it for at least 30 days before you can return it, as it does take a while to get used to a new mattress.
4. Rest Assured Adleborough 1400 Pocket Ortho Mattress – £439 – extra firm
I’d put the Rest Assured Adleborough 1400 roughly on a par with the Venice 1400 (see #1). The main difference is that the Adleborough is very firm, which won’t suit everyone (see the earlier waffle about getting the right firmness level).
It gets similar reviews (4.7/5), has the same number of pocket springs, is a similar depth and comes with the same 5 year guarantee. It also has the same downsides of mostly using synthetic materials and only being one sided.
On the plus side, it’s another Rest Assured mattress which has won an award from the Good Housekeeping Institute. It’s also a mattress which comes with a 60 night comfort trial period via Mattress Online. As with some others on this top five, you need to read through the terms and conditions first as there are some restrictions.
As with most Rest Assured mattresses it is ‘hand tufted’. That’s another piece of mattress-related jargon which means that it is held together with button-like things on top. It’s a way of ensuring a mattress keeps its shape and is seen as a positive thing.
5. Rest Assured Novaro 1000 Pocket Ortho Mattress – £349 – medium/firm
Our final choice in our Rest Assured top 5 is the Novaro, which is at the budget end of their range.
This mattress won’t dazzle your friends and family with its remarkable specification – but it’s a solid choice for the price.
It uses pocket springs whereas some mattresses around this price range use inferior ‘open coil’ springs. There are 1000 springs on the king size model or less on the smaller versions. That number will give adequate support to average sized people. You may want a higher spring count if you are well above average weight.
Customers rave about this mattress. It currently scores 4.7/5 from hundreds of reviews. Some even say they’ve bought more than one Rest Assured Navaros. The main gripe is that there aren’t side handles, which makes moving mattresses a bit tricky.
Keeping the design simple
The design and construction of the Rest Assured Novaro is relatively simple. There aren’t several layers of memory foam, wool or latex but it does have a ‘soft touch knitted cover’ and uses ‘polyester comfort fillings’. It does have ‘zoned’ springs though which is an effort to vary the amount of support you get to your back and hips. This is a feature that you generally find on more expensive sprung mattresses.
The depth is adequate at 24cm. I would be wary of sprung mattresses which are less than 20cm deep but 24cm is fine. The tension level is medium/firm.
Equally, the five year warranty is about what you would expect for this price. It’s half what you might get on a Sleepeezee pocket sprung mattress but it’s OK.
Much more impressive is that you get a 60 night trial period (via Mattress Online). This allows you to swap it for another model as long as you stick to the rules of the trial.
One thing I don’t like about this mattress is that it is single sided. Mattresses with simple designs (like this one) are often double sided which can help prolong their lives.
Overall though, it’s a good mattress for the price.
