We like: Removable machine-washable cover

We don't like: It's a bit bouncy and hard to rotate, no sleep trial

Exclusive to online retailer MattressNextDay, the Breasley Select Plus Memory 1000 Pocket is already cheaper than the average pocket sprung mattress. Now it is on offer for £229, which MattressNextDay says is a £90 saving on the full price.

This 21cm-thick double mattress includes a 14cm pocket spring core over a shredded polyurethane base layer, covered by various layers of foam and memory foam. It's described as medium firm, but in our independent tests it was rated 7.2 on a scale from 1 (very firm) to 10 (very soft).

Despite the foam layers, it doesn't feel overly warm to lie on when you get into bed, so it should suit most people.

We like: It feels cool to sleep on

We don't like: No sleep trial offered

This mattress is delivered rolled and vacuum-packed, directly to your door. You can't try it out in shops, but it does come with a 10-year manufacturer guarantee.

The 29.5cm-thick double mattress includes a 26cm pocket spring core covered by three thin layers of standard polyurethane foam (2cm, 1.6cm and 1.4cm) with different densities.

It's pretty bouncy, so it may not be suitable for those with fidgety sleep partners.

We like: Easy to move around on

We don't like: No handles for moving or carrying

This mattress has a 16.5cm micro pocket spring layer surrounded by fibrous filling. On the surface closest to the body, there's a 2cm layer of memory foam, which Silentnight claims is 'ideal for sink-in snoozers and designed to gently hug you to sleep, moulding with the contours of your body.'

As the foam layer is only on one side of this mattress, it can’t be flipped over, but you may need to rotate it from head to foot to help keep it in the best condition.

It’s available on a 60-night comfort exchange programme and comes with a five-year guarantee, too.

We like: The 10-year guarantee

We don't like: It's bouncy

It's very rare that we get to feature an Ikea mattress in our deals page, but you can still snap up this already cheaper-than-average pocket sprung mattress for just £199 now, saving £30.

It combines a 15.5cm pocket spring core with two layers of foam on top.

Based on our independent assessments, it's rated 4.2 on a scale of 1 (very firm) to 10 (very soft).

It comes with a 10-year guarantee.

We like: It's breathable

We don't like: It's bouncy

Formerly known as the Original Hybrid, Emma says that this bed-in-a-box foam mattress has 'unrivalled temperature control and unbeatable comfort'. Its zoned pocket spring core is topped with layers of pressure-relieving memory foam, and there is a 200-night trial, a 10-year guarantee and ‘hassle-free returns’ on offer to tempt you.

The brand says this is a medium-firm mattress and our lab tests confirm this. In our independent firmness tests, this mattress ranked as 4.7, with 1 being the firmest and 10 the softest. 

But will this mattress support your spine sufficiently, or will it sag and soften over time?

We like: It's easy to turn over on

We don't like: There is no trial nights offer

The EZE Hybrid Ultra mattress may catch your eye with promises of long-lasting memory foam, pressure-relieving breathable layers and pocket springs to optimise support while you lie down, plus a soft-touch fabric cover. But we've seen it on offer before, so there's no need to panic buy. 

Although EZE describes it as a hybrid, the large pocket spring core means we class it as pocket sprung (despite the foam layers). It's marketed as a ‘soft mattress’. In our independent firmness assessments, we marked it as 7.1 firmness, on a scale from 1 (very firm) to 10 (very soft).

Delivery is free and there is a 10-year warranty. 

To see if it's worth buying now, check out our full EZE Hybrid Ultra Mattress review .

There's currently a 10% discount on all sizes at the EZE website , with the double reduced to £494.

We like: The washable cover

We don't like: This mattress doesn't benefit from Emma's generous trial period

This hybrid mattress from Emma combines foam, aqua gel and pocket springs, promising pressure relief.

The Emma Smart Hybrid is sold only in shops, unlike the bed-in-a-box mattresses we're used to seeing from Emma. Some retailers offer a trial, but you’ll need to check exactly what deal is available from where you buy. The usual trial nights offer you get when buying directly from Emma may not apply.

So should you buy it? Check out our full Emma Smart Hybrid review to see.

You can currently get this double mattress heavily discounted to £460-£499 at online shops such as Land of Beds and MyNextMattress .

We like: The cover is removable for washing

We don't like: It could be easier to move about

The Emma Diamond mattress combines pocket springs and foam for ‘outstanding comfort and support’ according to the brand.

It's constructed from a combination of pocket springs and foam layers. Inside you’ll find a 13cm core of pocket springs, on top of which is a 6cm layer of foam and a separate 3cm layer of memory foam. Below the pocket spring core there’s a thinner layer (3cm) of foam.

Unusually, the Emma Diamond Hybrid isn't sold at the manufacturer's own website – only in other shops. That may be more convenient for you, but does mean that the retailer might not have the same generous free trial that Emma provides directly. Double check to see if there's a trial available where you buy it from.

So should you buy it? Check out our full Emma Diamond Hybrid review to find out.

You can currently get this double mattress discounted to £799 at online shops such as Land of Beds  and MyNextMattress .

Lisa Galliers, Which? mattress expert, says:

'Don't panic about buying a mattress purely because it's on sale because there are plenty of discounts throughout the year. Some of the mattresses in this deals round-up have been available at the offer price for a while, but are still a good price for the mattress. 

'We've also tested a range of good-value mattresses from brands that don't usually offer discounts – so if you want to keep costs down, you can still pick up a decent mattress for a fraction of the price of some.'

Whether you're after an Emma mattress or want to swap your old mattress for a new memory foam one, it's worth keeping an eye out for sales on your chosen brand's website. Social media can also be a good place to spot a bargain. 

Offers come and go throughout the year, but the deals might not be on the particular mattress you want, so check the T&Cs. Also, we've started to spot deals being swapped between the same mattress but with different cover options.  

Make sure you're ready when the discounts start. Compare mattresses to find out which ones will be a dream and which could turn into an expensive nightmare – and don't forget that retailers might have other sales in-store.

You might have spotted Dormeo mattresses on TV or via ads popping up on Facebook – we've seen a range of deals available, along with free gifts such as pillows and duvets on top of existing price reductions. And, although its mattresses can be found through other retailers, in the past we've noticed that buying direct from Dormeo can sometimes save you a small amount in addition to any free gifts it may be offering. 

So we'd suggest you check the website as a starting point. We've seen discounts of up to 60% in the past.

The Emma Original mattress used to be one of the most popular models on the Which? website. 

This bed-in-a-box brand delivers its rolled-up mattress direct to your door – it currently offers a trial of 200 nights. From what we've seen since we started this page, Emma offers a variety of deals available at different times, so keep an eye on the website and social media because you're bound to find a deal. The CMA is currently investigating Emma regarding its sales, and customers have recently reported issues with delivery. We've been in touch with Emma and the company has said it's dealing with the issues. 

The best discount we've seen regularly is around 50%, although we've also previously seen even bigger savings, such as 65% off some mattresses.

Another bed-in-a-box mattress brand, Eve is now owned by Bensons for Beds. You can find deals on the Eve Sleep website and at other retailers. Like rival mattress manufacturer Nectar, Eve offers a one-year sleep trial, so you can try out the mattress and, if you don't love it, send it back free of charge. 

Be warned, though – if you buy an Eve mattress via another retailer, such as Argos, the trial nights offer might not apply.

As a guide, we've seen deals offering 20-30% off, and up to 50%. Check the T&Cs before you buy, as these discounts often apply only to certain mattresses or if you spend above a particular amount, or for new customers. Eve seems to swap deals fairly regularly between its mattresses.

You might not see Ikea mattresses on offer, but that's because they're generally good value for money at full price. We've got 12 of them on our website, ranging from £99 up to around £689, with an average price of £361.

Not sure which one to go for? Head to the top five most popular Ikea mattresses to choose from there.

Another brand that's no stranger to a deal, Simba mattresses arrive vacuum-packed in a box to your door. Simba offers free returns and its website states that it won’t ask you to get the mattress back in the box for the return journey. 

We've spotted a range of deals from Simba offering 25-40% off. As a rule, 30-35% off is a good deal. Do check the T&Cs, though, as there can be conditions attached – such as a minimum spend or a discount that only applies to a particular mattress. The CMA is also currently investigating Simba regarding its sales.

Want to make sure you buy one to suit your budget? Find out about the best mattresses using our handy guide. 

Sleep trials – commonly offered by online-only, bed-in-a-box mattress brands – allow you the time to try out a mattress to see if it's the right one for you. If you don’t like it, you can return it within the trial period. 

This can be useful if you're not sure which type of mattress will suit you best.

A long sleep trial lets you try your mattress during different seasons and gives you time to adjust, which is particularly important if you’re switching from springs to foam. If you have back pain, for example, it could take quite a while to get used to a new mattress.

Not all sleep trials are the same, though, and some have strings attached. 

If you're buying a mattress that offers a sleep trial, check the T&Cs first. See how many nights you'll need to keep it for, if you need to use a mattress protector and what you need to do to return it if it's not right for you.

Also, bear in mind that if you buy from a third-party retailer, the terms of a sleep trial – and whether they're offering one at all – might differ from those you get if you buy directly from the brand.
