Bed-in-a-box brand Emma has launched its "biggest sale of the year", and there's one deal I have my eye on. The Original Pro Mattress, now £607.24 in a king at Emma, down from £799. This is the brand's most popular model thanks to its enhanced cooling tech and its targeted support for side and back sleepers.

Emma beds are frequently featured in our guide to the best mattresses you can shop online, and the brand's Original Collection provides excellent value for money. Thanks to its cooling and soothing feel, the Original Pro, as one customer puts it, "is perfect for a side sleeper and, in this blistering heat, still comfortable and airy too."

While there's up to 35% off in Emma's sitewide sale, this 25% off discount on the Original Pro is the Emma mattress discount I recommend to side and back sleepers. Plus, no matter when you buy, you'll always get a 200-night sleep trial and a 10-year guarantee.

Who should buy the Emma Original Pro mattress?

The Emma Original is recommended to back and side sleepers, as its targeted support spring system is designed to add extra cushioning along side sleeper pressure points, meaning the shoulders and hips. Meanwhile, more support is added to areas that need better alignment (such as the lumbar region and the edges).

While the Original Pro aims to balance support and comfort, Emma discourages stomach sleepers to invest in the Original Pro as its support isn't firm enough.

The Emma Original Pro, along with the Original Elite, has the most advanced temperature regulation of the Original collection. It relies on graphite-infused foam to dissipate body heat, making it a top reccomendation for hot sleepers.

Want something firmer? Try the cheaper Emma Original

As mentioned above, the Original Pro isn't supportive enough for stomach sleepers. The best mattress for stomach sleepers are often on the firmer side to ensure proper spinal alignment to avoid back pain. Luckily, the Original Mattress uses denser foam for a firmer feel to accommodate front sleeping. Its cheaper than the Pro, too, at just £483.69 (was £599) for a king with code SCHOOLSALE. As with the Original Pro, the same benefits apply to the Original: a 200-night sleep trial, free delivery and returns, and a 10-year guarantee.
