For the highest standards of quality and safety
The Wentworth Mercer® 3000 Pocket Pro Mattress provides your guests with a luxury nights rest.
Commercial use
Designed for high turnover commercial properties such as hotels, student accommodation and private rentals. This mattress adheres to UK Fire Safety Regulations (BS 7177:2008 – Crib 5 / Ignition Source 5) for added reassurance.
Long lasting support
A core of 1000 pocket springs adapt to the movement and weight of each sleeper for tailored support. Helping to ease aches so your guests can enjoy a better night's rest. Made from durable steel, these springs are sturdy to stand the test of time.
An additional two layers of 1000 mini springs provide a bouncy feel for added comfort. These springs help reinforce the natural fibre comfort layers to extend use.
Natural comfort
Two layers of a wool, cashmere and silk blend provide cosy comfort for your guests. These fibres are naturally insulating yet breathable to achieve ideal temperature regulation. This keeps sleepers at a comfortable temperature at any time of year.
Adding to the comfort of the mattress are two layers of polyester fibres. These breathable layers increase airflow to provide a fresher feel.
Completing the comfort layer is a blend of cotton and polyester to create two layers of moisture-wicking comfort. Helping to provide a dry sleep space and reduce a build-up of odours, ideal for high turnover properties.
Sturdy feel
Rated firm, this mattress is a great choice to suit most sleeping positions and sleeper weights. Helping you provide a supportive feel to a wide variety of guests.
Traditional design
This Wentworth Mercer mattress provides lasting stability and durability with time honed techniques. It is traditionally hand side-stitched, attaching the side panels of the mattress to the spring unit. This enhances stability and reduces motion disturbance.
Each layer of this mattress is tufted together to increase durability and stop layers from shifting. This process means the mattress is glue-free and easy to recycle at the end of use for better sustainability.
Longer use
Made with commercial use in mind, this mattress is double-sided. This means you can get double the use without needing to replace it as quickly. Ensure you rotate the mattress top to toe and flip seasonally. This promotes even wear and helps the mattress retain its shape.
Quality guaranteed
This mattress has been expertly made in the UK, adhering to the highest standards to deliver ultimate quality.
Featuring a 10 Year Guarantee, you can purchase this mattress with absolute peace of mind.
