The 6 Best Mattresses Under £400
1. Wayfair Sleep Essentials Memory Foam Mattress – £134.99
Boasting a 4.4 star rating with over 3000 reviews, the double-sized Essentials Memory Foam Mattress by Wayfair Sleep is one of the absolute best mattresses under £400. Its 15cm thickness is constructed from layers of high density memory foam that provide the just-right balance between soft and firm, while also relieving pressure on bones, joints and muscles. This mattress is ideal if you or your partner are restless sleepers – memory foam absorbs motion, so one person's restlessness won't impact the other.
If you're a fan of the classics, you can't do better than the Symple Stuff calthorpe pillow-top mattress for under £400. This breathable medium-firm mattress is hypoallergenic and doesn't transfer motion, thanks to its pocket sprung support. Each pocket spring works independently to offer an all-over and average support towards the feet, legs, hips, waist, shoulders, neck and head. This mattress also provides excellent shock-absorption and resilience, which not only caters to your vertebra well, but helps to adjust and correct your sleeping posture.
Sliding into our best mattresses under £400 list, the Silentnight Ashley Mirapocket 1200 memory mattress is a great addition to any bedroom. This mattress includes 1200 individual pocket springs held under tension in their own fabric pockets, meaning they respond independently to a sleeper's weight, delivering individual tailored support. The Mirapocket spring system offers zoning across the mattress, which is scientifically proven to provide excellent spinal alignment and overall support. This mattress is also hypoallergenic, so you can sleep without worry in a sound environment.
Look forward to falling asleep faster and sleeping for longer with the Dormeo select hybrid mattress. For less than £400, you can enjoy full body support every night with the medium-firm memory foam construction. The airmesh sides help move humid air out and fresh air in, which in turn enhances a constant air circulation throughout the mattress. And if that isn't enough persuade you, the 4.6 star rating just might.
