How to choose a mattress

Consider your budget. To ensure you're getting the best price on your chosen new mattress, always shop around and compare prices. or hold out for the regular sales or special promotions that take place throughout the year. You could also open the live chat box and speak to a company representative to talk through the specifics of the available deals.
Decide on the type of mattress you want. From pocket sprung or memory foam to hybrid or orthopaedic, there are a plethora of mattress designs to choose from. Each has its own pros and cons, so it's important to do your research before taking the plunge.

How to spot a good deal on a mattress?
When researching mattresses, you’ll quickly discover there are always deals to be had – no matter what type of mattress you’re looking for.
Brands like Simba and Emma often run regular offers, and stores like Dreams and Bensons for Beds hold sales with discounts on select mattresses.
If you know you need a new mattress soon, January sales can be a great time of year to buy, with generous stock clearances and big discounts.
However, if you can’t wait for sale events, then make sure to shop around and compare prices before parting with your money.
You might also want to upgrade your bedding or grab a mattress topper while you're at it.
What is the best month to buy a mattress?
While it's true that mattress retailers tend to drop prices on certain days, such as bank holidays and during big shopping events, you'll find a great mattress deal in pretty much any month of the year.
According to The Sleep Foundation, many mattress brands introduce new models in mid to late spring.
This means that the prices on older models are often slashed dramatically, so spring could be the most sensible time to buy a mattress.
Should I wait until Black Friday to buy a mattress?
Mattresses need to be replaced every six to eight years: if yours is on the way out, you'll probably find yourself desperate to buy a new one as soon as possible.
Black Friday takes place in November, so there's not long to go.
Although it's one of the best times to buy a mattress for less, there are risks involved with waiting until the shopping holiday.
As many people buy mattresses on Black Friday, those with the biggest discounts tend to sell out quickly.
You can generally find a good deal at any time of the year, so it might be best to shop the sale now while your favourite model is still in stock.
How much do mattresses cost?
A good spring mattress doesn't have to cost much more than £150 for a double.
Memory foam mattresses tend to be a little more expensive, but you can find good quality doubles from £300.
Hybrid mattresses, which contain a mix of foam and springs, are more expensive still and can cost anything from £400 to £1,000 and above for a double.
Other factors to consider when you buy include the length of the trial period you'll get (most internet-only brands offer 100 nights), as well as shipping costs, which can quickly send your overall costs soaring.

The best sleep routine and environment
Thomas Høegh Reisenhus, TEMPUR® sleep specialist & sleep counsellor, reveals the key components of a good bedtime routine and environment...
A sure-fire way to facilitate a better night’s sleep is to practice good sleep hygiene.
Establish a sleep routine that works for you and stick to it.
This will help your body establish a consistent, natural sleep-wake cycle which can do wonders for your overall sleep quality.
As such, try to avoid making up for lost sleep with a lie-in.
Instead of sleeping in, spend your morning reading a book in bed or having a leisurely coffee in the kitchen.
Ensure that your bedroom, bedding, and sleepwear are fit for purpose too.
The ideal sleep environment is dark, quiet, and cool – much like a cave.
If you find unwelcome sources of light are keeping you up, consider investing in an eye mask or black-out curtains.
Adding soft furnishings can be a great way to reduce noise, with the surfaces having an absorptive quality, but if this doesn’t work, consider embracing a soothing soundtrack to block it out.
In terms of temperature, try to keep your bedroom at 18°C. You can further reduce the risk of waking up due to overheating by ensuring that all your bedding and sleepwear is made with natural, breathable materials such as cotton and linen.
Bear in mind that everyone is different; what might work for most, may not work for you!
Whilst knowing how much sleep you should get, how to overcome common barriers, and practicing good sleep hygiene can facilitate a great night’s sleep, if you continue to struggle with sleep or fatigue persistently, do not hesitate to visit a doctor or health professional for support.
