Looking to upgrade to a more comfortable night's sleep during the summer heatwave? Award-winning mattress brand Emma is giving away free gifts when you switch to a new mattress.

If you buy the Emma Original Elite mattress, you can get a £100 gift card to shop at John Lewis and a free mattress protector, a pair of cooling pillows, a spring-autumn duvet, and pillowcases worth up to £379.

You'll also be treated to free cooling pillows and a mattress protector worth up to £242 when you upgrade to the Original Pro mattress. And if you want the most affordable way to snag those cooling pillows, you can get a pair for free worth £80 when you upgrade to the Emma Original — a model that's earned over 25 industry awards.

A good night's sleep can be difficult to achieve during the warmer months, but your sleep setup can make all the difference.

Sleep expert Dr Deborah Lee said: “Warm weather can make your current sleep discomfort feel a lot worse. If your mattress is starting to sag, or your pillows feel like you’re lying on a sheet of paper, then your bed could be disturbing your sleep without even realising it."

Most sleep experts also recommend replacing your mattress every five to eight years, as older mattresses can lose support over time and contribute to aches, pains, and disrupted sleep.

And Emma isn't the only mattress brand that offers cooling technology across its products. Award-winning British brand Simba sells several variations. Likewise, Otty sells its own versions to help keep you cool at night.

Not ready to commit to a brand-new mattress? One of the best mattress toppers in the UK can be an easy way to refresh your current setup and help extend the life of your mattress until you’re ready to make the switch.

Emma's hybrid airgrid mattress is designed with seven layers to provide the ultimate comfortable support. Created with memory foam, it adapts to your unique shape and distributes weight across multiple zones to promote relaxation. It's also built with Airgrid technology, so you won't feel heavy or like you're sinking into your mattress. The mattress comes with a cover that's easily removable and washable when cleaning.

Stay cool all season long with Emma's most affordable mattress, built with its Infinity technology for extra breathability. The mattress is designed with five different layers, including memory foam, which adapts to you. It also comes with edge-to-edge pocket springs that let air move freely through your mattress, helping you maintain an ideal temperature every night.

Emma is one of a slew of so-called bed-in-a-box brands, which roll and vacuum-pack all-foam or hybrid mattresses so they can be delivered without any hassle. Most of these companies will collect your old mattress and recycle it — saving you a trip to the tip.

They also sell some of the best mattress toppers in the UK, duvets, bedding, and more.

Buying a mattress online might seem riskier than heading to your local showroom. To reassure customers, the team at Emma offers a 200-night trial period on all mattresses from its online store.

If you're unhappy with the mattress at any point during the first 200 nights, you can organise for free collection and a full refund. That should reassure anyone curious about trying an all-foam or hybrid design.
