For the highest standards of quality and safety
Experience the lavish feeling of a luxurious mattress. The Wentworth Mercer Deluxe Wool 3000 Pocket Mattress has everything you need for a wondrous slumber.
Decadent fillings
Sumptuously filled with natural wool fibres for deep, plush comfort. These fillings inside this mattress provide all the snuggle-worthy cosiness you need for an undisturbed slumber. The wool elements are naturally temperature-regulating, which means the mattress is perfect all year round.
It is topped off with a layer of soft synthetic fibre which is inherently breathable. Enhancing the air flow through the mattress, creating a cooler, refreshing sleeping environment.
Traditional design
The core of this mattress is made up of 3000 pocket springs. This spring system fully supports your body by actively adapting to your unique body shape. The springs react individually to each other, which enhances the support and targets where you need it most.
The steel springs have been twice tempered which prolongs the durability of the metal. The design technique of tempering the springs allows the metal to hold its shape for longer which enhances the bounce-back rate of the spring.
Small details
Along the border, two rows of hand sided stitching have been added. This helps to increase the durability around the mattress edge. Enhancing the stability so you can sleep right to the very edge.
Wrapped in a soft viscose fabric and finished with a time-honoured tufted design. The wool tufts help secure the fillings in place and ensure there is no shifting, shape loss or sagging.
Long-lasting use
Crafted with the highest quality materials, using time-honoured techniques so you can enjoy a marvellous sleep that you deserve. Backed with a 5 Year Guarantee as well as a 5 Year Warranty.
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.

I actually had the Super King. Very Firm initially, much more so than a medium should be. Once I added a topper and slept on it for a month it started to ease a little. It is holding its shape and is now comfortable but it is firm not medium, even though it says medium so be prepared for this. I suspect it will ease more with time
