Description

Elevate your sleep into a heavenly slumber with the Wentworth Mercer Deluxe Wool 4000 Pocket Mattress.

Incredibly cosy

Elegantly filled with high quality natural fillings for a truly decadent rest. It features a layer of cosy wool fibres which are a great natural insulator. The fillings continuously regulate your body temperature whilst you sleep. So, you won't wake up if you are too hot or too cold.

These fillings are topped with polyester fillings. This material is very breathable which enhances the airflow through the mattress for a cooler rest.

Sprung construction

The core of this mattress is made up of 4000 pocket springs. The springs are made to actively adapt to your shape and movements. Because of its pocket design, the springs move independently to each other, allowing for more personalised support. The design allows for an undisturbed slumber because of it's no motion transfer element.

The sturdy steel of the springs have been twice tempered. This special design helps to improve the longevity of the springs and also enhances the bounce-back reaction. With the improved bounce-back rate, the springs expertly soothe built up pressure, aches and pains.

Strong border

Along the edge of the mattress is a thick rod wire. This rod wire secures the springs in place and creates a firmer mattress edge. With the springs right to the end of the mattress, this maximises the sleeping space so you can roll, stretch and sleep onto the edge.

Additionally, 2 rows of hand side-stitching have been created along the border. Stitched into the spring system for a more sturdy and durable finish.

High-quality finish

Wrapped in a cosy viscose cover and finished with an excellent standard. This mattress features a traditional tufted design. The construction of this creates a more stable sleeping surface by holding the fillings in place.

Excellent craftsmanship

Expertly handmade in the UK. This mattress has been crafted with time-honoured techniques, ideal for a high-quality finish. It comes with a 5 Year Guarantee, plus an additional 5 Year Warranty so you can buy with the utmost confidence.

Please note: The mattress cover material might look different than pictured but this will not affect the comfort or support of this mattress.
