How we test mattresses at Ideal Home – assessing comfort, motion isolation, and much more

Wondering how we test mattresses at Ideal Home? We're here to explain all.
To compile Ideal Home's guide to the best mattress you can shop, our dedicated team of mattress reviewers regularly tests mattresses from a wide variety of brand names to find the best-in-class.
We aim to test the bestsellers within a brand's product range (after all, they're usually bestsellers for good reason) and review brand-new launches to compare innovations in the world of sleep to our tried-and-tested favourites.
We know that a mattress is a significant investment and a key factor in how well we sleep, so we try to ensure our tests demonstrate exactly how each mattress feels to sleep on to make it easier for you to assess whether it's the right choice for you.
How we test mattresses at Ideal Home
Why you can trust Ideal Home
We think there's only one way to test out a mattress, and that's by sleeping on it. Even if you're able to test a mattress in-store, a quick lie down in a mattress showroom isn't the same thing as actually sleeping on a mattress for eight hours, night after night.
That's why our review team tests all the mattresses we review in our own homes. This way we're able to form a full picture of what the mattress is like to sleep on long-term.
Each mattress is slept on for a minimum of two weeks – in most cases far longer – before we write our review. This enables our reviewers to adjust to each new sleep surface and assess a mattress's performance over a prolonged time period.
How we test mattresses
In the course of our testing, we've developed extensive knowledge of what makes the best night's sleep – from comfort to temperature regulation, and motion isolation to edge support. We've broken down everything we assess during mattress testing, and how we assess it, below.
1. How we test comfort
To test the comfort of the mattress, we make sure to lie in all three sleeping positions – side, back, and front – to assess the mattress's cushioning and support. In each sleeping position, we assess whether the spine can rest in good alignment.
For side sleeping, we also assess whether there's enough surface cushioning around the hip and shoulder or if this is lacking and we experience soreness, numbness, or pins and needles in the joints during the night.
Because all of us are different, and our weight and any health problems – such as back or neck pain – can all affect our mattress preferences, we also try to take this into account in our reviews. We assess if a mattress is a soft sleep surface that would suit lighter-weight sleepers or a firm surface better suited to heavier-weight sleepers.
We also enlist the help of a partner for a second opinion or invite friends and family to come and stay the night to get a range of viewpoints. After all, one person's 'too firm' can easily be another's 'just right'.
2. How we test temperature regulation and breathability
We test temperature regulation and breathability by noting if the mattress causes us to overheat during the two-week testing period.
If possible, we try to get a range of self-diagnosed 'hot sleepers' and 'cold sleepers' to test the mattress for a range of opinions.
If a mattress feels excessively warm to the touch after we've been lying on it for the night or it causes us to wake up feeling hot and sweaty, it's deemed to lack good temperature regulation and breathability. If we remain at a steady temperature throughout the night don't experience any overheating, we rate the mattress as offering good temperature regulation.
We ensure the rest of the bedding remains consistent throughout each test.
3. How we test motion isolation
To test the motion isolation of the mattress, we lie on one side of the bed and get a testing partner to lie on the other side. We then ask our testing buddy to roll over, and generally toss and turn, to mimic a restless night's sleep.
A mattress has poor motion isolation if we can feel our testing partner's movements reverberate through the mattress onto our side. A mattress with good motion isolation means any movement is dampened and we weren't disturbed.
4. How we test responsiveness
We assess mattress responsiveness by lying on the mattress for five minutes and then changing our sleeping position.
A mattress that lacks responsiveness – such as a soft memory foam mattress – will mould around the body and form a ‘dip’ that can make changing sleeping positions difficult. In contrast a responsive mattress will be very easy to turn over on.
We also perform a 'hand press' test where we press our hand into the mattress surface to see if there is an impression left behind and how long it takes the mattress surface to spring back into shape.
5. How we test edge support
We test edge support by lying on the edge of the mattress to see if it dips.
A mattress with good edge support should have an even surface tension across the entirety of the mattress and support the body even on the edge. Poor edge support means the mattress dips and there is a risk of rolling out of bed when laid on the mattress edge.
We also sit on the edge of the mattress to note how much it sinks or dips.
As well as these practical tests, we also assess each mattress on other vital criteria; whether it comes with a sleep trial, how easy it is to care for, what the delivery process is like, and its value for money.
Where possible, we also take into account any third-party reviews to see if other owners opinions of the mattress are in line with our own.
6. How we assess sleep trials
We think a mattress sleep trial is a great benefit as it allows you to test a mattress at home and see if it suits your bed and body before you commit.
We check whether the mattress comes with a sleep trial, and tell you how long the trial period is.
7. How we assess ease of care
There are some things you might not realise are useful in a mattress, like side handles – which make mattress flipping or mattress rotation far easier to ensure even wear and tear – or a machine washable cover that will help with how to clean the mattress.
We note useful features like this that will help you to care for your mattress.
8. How we assess the delivery process
To assess each mattress's delivery process, we note what the delivery options are. Some mattresses may be delivered to the doorstep only, others to your room of choice, or there may be the option of 'white glove' delivery.
We'll also tell you whether the mattress is delivered rolled, as a mattress-in-a-box, or flat as this can affect how easy delivery is for those with awkward access requirements. And we note any mattress off-gassing when the mattress is removed from its packaging.
9. How we assess third-party reviews
Where possible, we also research third-party customer reviews of each mattress we test. We summarise any common themes, both positive and negative, and note whether these are in line with our experience of the product.
This helps us to assess things such as longevity, which we're not initially able to test during the review period. However, where possible, we do update our mattress reviews over time to share how the mattress is responding to daily use.
10. How we assess value for money
Lastly, we assess the mattress's value for money by comparing it to similar products we've tested. We let you know if we think the pricing is fair, or if there are better-value deals to be had.
We also alert you to any mattress deals we're aware of on the mattress to make sure you can find the best prices to shop.
