1. Emma Medium Firm Mattress

Branded as the key secret to a great night’s sleep, the Emma Original medium mattress has been the UK’s most awarded mattress with consistent high ratings among customers. Memory foam mattresses are becoming more popular as the years pass as people are opting for foam rather than springs. If you struggle to get to sleep and stay sleeping soundly throughout the night, here are some of the benefits of an Emma Original.

Starting with the most prominent feature, the complexity of foam position in the Emma Original may be the key to fixing your sleeping pattern, no matter what side you sleep on. The bottom layer of the mattress consists of HRX foam which aids spinal alignment and helps support your entire back. This bottom layer also keeps the mattress steady, helping you keep as still as possible throughout the night.

The middle layer of the Emma mattress consists of visco-elastic memory foam which helps contour your body. With this, your weight is evenly distributed along the mattress, meaning that it can help relieve pressure from the more sensitive parts of your body.

The top layer of the mattress consists of Airgocell foam which helps regulate your temperature throughout the night. By absorbing moisture, this feature is fantastic in ensuring a high quality of airflow throughout the mattress helping you sleep easy. Equiped with a 200-night trial, it is no wonder the Emma Original is a top contender for medium firm mattresses across the UK.

The final core feature of the mattress is that of the Emma cover, which is both temperature-regulating and breathable. The soft and snug elastic cover fits the mattress like a glove, adding an extra bit of comfort for you to enjoy. The cover also has the key feature of handles on either side of the mattress, making it much easier to move and handle. This is great if you’d be moving the Emma Original yourself or if you struggle when lifting heavier items. Rather than lifting the mattress around, the handles allow you to both push and pull it instead.

With the benefit of the 200-night trial, the perks of the Emma Original don’t stop there. You also have a 10-year guarantee when you purchase the mattress and free returns if it doesn’t end up suiting your needs. Perhaps the Which? Best Buy mattress is exactly what you need. If you’re looking to include the Emma mattress in your list of medium firm possibilities, keep its supportive, pressure-relieving and breathable features in mind.
