If you've been looking for a sign to upgrade to a better night's sleep as autumn begins to roll in, this could be it.

Sleeper brand Emma has a new online sale where you can save up to 40% on mattress toppers, mattresses, mattress protectors, and pillows— so you can change your whole sleep setup.

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.

And that's not the only sale occurring. British brand Simba also slashed 30% off its award-winning mattresses.

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.

We've rounded up some of the best deals on Emma's online site below. If you're looking to dip into the savings, you have until September 21.

Its ThermoSync cover helps regulate temperature, keeping you cool and comfortable all night, while hybrid foam and pocket springs provide pressure relief and spinal alignment.

Ideal for all sleep positions, it's designed to deliver balanced support and reduced motion transfer.

Paired with a cooling pillow, it features four carefully designed layers — temperature-regulating foam to help keep you cool, a supportive foam layer for your head and neck, a soft comfort foam layer for added cushioning, and a breathable, removable, machine-washable cover for easy care.

The Cooling Comfort Pillow may be a better option if you're looking to manually customise its height. It comes with removable layers in a medium-to-soft support design.

And on top of that, the bundle also includes the Spring and Autumn Duvet, which is ideal for transitional seasons.

It's machine washable and designed with special temperature-regulating microfibres, so you can stay cool or warm, depending on the temperature.

If you need a mattress protector too, Emma is offering 40% off. In past sales, the mattress protector has only been on sale for 20% off, so now may be an ideal time to buy if you're looking for one of the best deals.

Save 40% on the Emma mattress protector

All of Emma's mattress protectors include a 14-night risk-free trial, free delivery and returns, and 0% financing. With Emma, you have the opportunity to spread the cost of your purchase with monthly instalments ranging from 3-12 months.

A mattress protector is a simple, washable cover that shields your mattress from spills, stains, dust, allergens, and wear — helping it stay clean, fresh, and comfortable for years while preserving your warranty on both mattress toppers and mattresses.

Emma's version is spill-proof, machine washable, and made with anti-allergen technology — so it's working overtime to keep your mattress safe and you comfortable.
