For the highest standards of quality and safety
True luxury with an unbeatable support output, the Wentworth Mercer® Natural Pocket 2000 Ortho Mattress is what dreams are made of.
Tailored to you
Holding a heart full of 2000 pocket springs, you will receive support personalised to your needs. These springs rest within fabric pockets and respond both as a team and on their own. Providing highly reactive and adaptable support.
They are able to flawlessly sense movement and pressure and then adjust their support output accordingly. Directing soothing and comforting relief to the most important areas. Pocket sprung cores are also excellent at aligning your neck, spine and hips regardless of your sleeping position.
Comforting fibres
Feel the comforting embrace of breathable fibres cuddling your body as you drift off to sleep. Two layers formed from a mix of cotton and polyester offer a cushioned feel for lasting comfort. Cotton naturally wicks away moisture, helping to promote a dryer, fresher sleep space. The polyester fibres increase this fresh feel by enhancing airflow to dispel heat and moisture.
Providing extra comfort and durability are two layers of soft white fibres. These layers are resilient and cushioning for longer lasting comfort.
Extra soothing relief
Rated extra firm, this mattress is the ideal choice if you are looking for orthopaedic support. Firmer mattresses create a sturdier surface that stops your body from sinking in too deep. Making it much easier to get in and out of bed. The strong surface will limit your spine from entering a curved position that can lead to aches. Expertly keeping your postural position in optimal alignment to soothe pains and limit their development.
High support
Across the border of this mattress it has been reinforced with two rows of side stitching and a rod edge design. Creating greater perimeter support to limit any dipping or sinking across your mattress. This allows you to benefit from a maximised sleep space. So you can sleep right up to the very edge without being woken by a ‘roll off’ feeling.
Quality you can trust
Perfected by the experts at Wentworth Mercer® and made in the UK, you can rest assured you’re receiving the highest quality. Designed to offer comforting indulgence, each mattress has been held to UK safety and comfort standards. Complete with a 5 Year Guarantee to cover any possible manufacturing faults. Gifting you restful and worry-free slumbers night after night.
This mattress comes with a 100-Night Comfort Trial - like all of our mattresses!
The trial lets you test your mattress for up to 100 nights. If it's not quite right for you, you can exchange it for a new one. To be eligible for the Comfort Trial, you'll need to purchase a mattress protector from MattressOnline with your new mattress.
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.

Firm, luxury mattress at a good price
Verified Purchase
I bought this as super firm mattress but it's medium firm. I compared both firm and super firm. Both are same as per costumer demand they use to send same for everyone. After use of a week it started sinking. I call customer care to replace it with another one they decline my request. Very disappointed and I can't use it. My wife is pregnant and she isn't comfortable in this. Spending £650 for this isn't good. I gave 3 star for its luxury look. Not recommended. It's not super firm/ firm mattress. It's just medium mattress.

The mattress is not extra firm. I would rate it as medium.

We love our extra firm mattress, had it over s month now and every night is luxury
Verified Purchase
Lovely solid mattress ideal for my needs. Due to the wool, cashmere and other natural products used to make the mattress, it warms up quickly when I'm in bed, so I don't need heavy bedding or electric blankets, etc. While not lightweight, it isn't nearly as heavy as other extra firm mattresses. Perfect for my back and neck injuries.
