The Pocket Sprung 1500 Mattress features individual pocket springs, which work independently to react to your body's movement and weight, offering complete support. Pocket Sprung 1500 Mattress has a medium feel to it and is perfect if you are looking for a mattress with cooling properties and a good combination of pressure relief and support. The mattress features a tufted damask cover and quilted border. Solving the problem of overheating during the night, in addition to the individual pocket springs, Pocket Sprung 1500 Mattress offers a good level of support as the individual pocket springs react to your weight, as well as your movements during the night. The pocket sprung core features individual springs, each encapsulated in a fabric pocket, providing a comfortable feel for the mattress. Unlike interconnected coil mattresses, pocket springs work independently of each other and the flexibility in the pocket springs allows the mattress to respond to the shape, weight, size, movement and sleeping patterns of your body.
I weigh 45kg, my son weighs 65kg, we both tried the mattress and we both could sleep very well on it. It is one of the few mattresses with medium to soft springs. Since I'm a side sleeper a mattress with softer springs is generally recommended. This mattress is one of the cheapest spring mattresses in December 2023 with a price of £91,66. There is also a variant with memory foam. The decision was hard but I decided to buy this one with the polyester filling on both sides. It feels like lying on clouds. Me and my son are very happy about this purchase. I can recommend this product to all people who weigh less than 65kg.. Shanthiny. London. Tue Dec 26 2023

It’s deep and raises the height of my bed quite significantly which is what I was looking for. It is softer than I was expecting but ok so far for sleeping on. Large handles on the mattress make it a little easier to get upstairs but would have benefitted from a handle on one end as well as the sides. Maybe a bit too soft and bouncy.. Siobhan. Kent.

The Sareer is a beautifully crafted and finished mattress of substantial construction. It was delivered flat by Panther (despatched ahead of original 29/1 schedule) and my only regret was not getting it taken upstairs due to Covid as it is quite heavy. The sides hold their shape well, the tufting is soft and springy also the stitching and finish are superb. It is also reversible for maximum comfort and longevity. I seem to have the 1500 pocket version. It really is super mattress and I recommend.. Alexandra. Epsom, GB. Fri Jan 08 2021
