Pocket spring mattresses last between 8 to 10 years on average, although this can be extended with the right amount of care. As a general rule of thumb, the higher the spring count, the higher the durability. Thanks to the additional strength provided by the individual springs, the strength and robustness of the mattress is significantly increased. A pocket sprung mattress also requires regular flipping to reach its full lifespan, a Winstons pocket sprung mattress will last you a lifetime due to our high quality build and this is why we offer a 30-year guarantee with every mattress.
