This mattress features a sumptuously soft pillow-top layer of plush fillings for extra comfort and cushioning. Featuring edge-to-edge 800 individual pocket springs and features an added layer of 2cm of memory foam that responds to your temperature and spreads the weight evenly. This mattress will provide the best of both worlds and help you get the best night’s sleep.

This mattress is amazing. It arrived in a box as stated and I opened it and put it on the base as suggested. It was vacuum sealed which made it easy enough for one person to get out. The mattress came with its own tool to cut the plastic off. As I got halfway through cutting the plastic the mattress sprung to life. Over the course of the next few hours it grew until it was 30cm deep. The quality of the mattress is excellent. Very good value for money. I cannot fault this mattress at all. I very happy with the choice. Ellen. Southend-on-sea, GB. Wed Jul 08 2026

Combining individually pocketed springs and a latex foam layer allows the mattress to offer you support and comfort in abundance

Bought this due to lower back pain. Was a little unsure if it would be firm enough, but its great, i would describe it as medium/firm. It arrived well packed in plastic and was easy to manoeuvre upstairs, it opened up easily, I placed it onto the frame after 48 hours and have now slept on it for a week. Not had 1 single pain. Very good price and even if it lasts only a couple of years, I've got a bargain and I know that a change of mattress was all that was needed. I'm not keen on the feel of 'memory foam' and found it difficult to find mattresses without it. Happy that I came across this one.. Aud. Fri Feb 23 2024
