For the highest standards of quality and safety
The Rest Assured Knowlton 2000 Pocket Latex Pillow Top Mattress is a cosy, responsive mattress that delivers personalised comfort for your best sleep ever.
Extra comfort
Enjoy the sumptuous, cosy pillow-top and sink into a 2.5cm layer of natural latex. The comfy, dreamy feel of this mattress will have you sleeping soundly. Latex is wonderfully elastic and springs back when you move, keeping its shape for years of high-performance use and wonderful rest.
Zoned springs
Paired with a support system of 2000 pocket springs, this mattress absorbs movement and minimises partner disturbance. A great choice for couples!
The springs move independently and are also carefully zoned to relieve pressure to key areas of the body. This means the springs have been carefully arranged to support your back, hips and joints to benefit overall wellbeing.
If latex isn't for you, why don't you check out the Rest Assured Novaro 1000 Pocket Ortho Mattress ? It has a fine blend of pocket springs and memory foam for ultimate support!
A clean sleep
The tight cell structure of latex makes it highly resistant to dust mites - it's hypoallergenic. It reduces allergens for a clean and fresh sleeping environment, night after night.
Long-lasting performance
All these layers are encased in a smooth damask cover, which is tufted to secure the fillings and ensure long-lasting performance. This mattress is single-sided, so there's no need to flip. Simply rotate top-to-bottom once a week for three months, then monthly thereafter to ensure even wear across the surface.
Premium quality
Rest Assured is a reliable, premium mattress brand with over 100 years of experience, based in Lancashire, the heart of the British countryside. Enjoy the security of their 5 Year Guarantee, so you can buy in complete confidence.

Have been impressed by this mattress. I had gone through 2 mattresses on trial before getting this one. I was very glad I didn't stick with the previous ones. This mattress has been comfortable from the off, it feels solid and good quality. Although it isn't advertised, the mattress is good at no roll together, there's no divot in the middle to fall into and it's solidly comfortable under your own side. Proper latex is much better than any geltex etc, it's worth getting over any of those variants. I've had nothing but good night's sleep on this mattress since it arrived. I don't ache when I wake up, which is a first for a long time. I was heartened to see reviews saying they were buying this as a replacement for the same mattress many years later. I can say already that this is very likely to be the case for me. Although I would look at one with a deeper latex pillow top.

I ordered this mattress as seen similar in a store and already had a mattress of the same brand . Delivery date was able to be selected to suit my requirements and mattress was delivered promptly and on time. The mattress is off great quality and as comfy as I thought it would be. I am enjoying several nights of restful sleep !

It's a nice mattress - comfortable but too soft for me. I was expecting it to be firmer. I've sent back and ordered a firm mattress.

A bit harder than hoped for but hopefully will give a bit
