For the highest standards of quality and safety
Transform your sleeping experience into decadent luxury with the Wentworth Mercer Deluxe Naturals 5000 Pocket Mattress.
Traditional springs
Actively adapting to your unique body shape, the strong support system in this mattress is made up of 5000 pocket springs. Made with sturdy steel that is encased in their own fabric pocket, allowing each spring to move independently from each other.
The steel has been specially twice tempered which enhances the longevity of the spring. It also creates a strong bounce-back movement for better pressure relief. Soothing aches and pains all around your body.
Luxuriously soft
Ambitiously filled with high-end natural fillings, this mattress is sumptuously cosy. Featuring layers of natural wool and cotton. The wool fibres are a great addition because of its temperature regulating properties. Allowing you to stay cool in the summer and toasty in the winter.
The soft cotton layer is inherently breathable. The fine construction of the fibres allows for more air to flow through, creating a cooler sleeping environment. Perfect for the hotter months, when you need to cool down during the night.
Reinforced border
The edge of the mattress has been constructed with a strong rod wire. This design helps to secure the springs right to the very edge for maximised sleeping space. With the help of 2 rows of hand side-stitching along the border for a sturdy, more durable mattress.
Timeless design
Wool tufts have been placed through the mattress to improve and secure the natural fillings. Keeping the fibres in place allows a sturdier sleeping surface. The traditional technique brings a timeless design to the mattress for a luxurious, high-quality look.
Long-lasting performance
This mattress is double-sided, ideal for long-lasting comfort. Simply flip and rotate the mattress every 3 weeks for the first 3 months and then the same process once every 3 months. This helps the mattress stay in the best condition and maximises the longevity of the product.
Time-honoured craft
The Deluxe 5000 has been expertly handmade in the UK, using long-established techniques. So you can trust that this mattress has been made to the highest quality.
With a 5 Year Guarantee, plus an additional 5 Year Warranty, you can buy with confidence.
Please note: The mattress cover material might look different than pictured but this will not affect the comfort or support of this mattress.
This mattress comes with a 60-Night Comfort Trial - like all of our mattresses!
The trial lets you test your mattress for up to 60 nights. If it's not quite right for you, you can exchange it for a new one.
It can take some time to get used to a new mattress, which is why we ask you to sleep on your mattress for 30 nights. If you're not happy with the feel after 30 nights, simply contact our Customer Service Team, and we'll arrange a mattress exchange.
