How often should you change your mattress? As a guide, after eight to ten years, but the condition of the mattress is what matters, not the date on the invoice. The following five signs will tell you whether yours has reached the end of its life.<\/strong><\/p>\n

A mattress wears out gradually, which is precisely why few people notice its end in time. The body gets used to the sagging spot, morning stiffness in the back sets in, and a person puts it down to age or the weather. The question \u201ehow often to change a mattress\u201c therefore doesn't have an answer in the calendar, but rather in what the mattress is still capable of doing \u2014 how it holds its shape, how it responds to pressure, and how one sleeps on it after six hours, not after five minutes in a showroom.<\/p>\n

\"How
The cutaway of the Royal I mattress shows what wears out first inside: the comfort foam layers above the core. The pocket springs in a foam encasement with a reinforced side generally last longer than the layers above them.<\/figcaption><\/figure>\n

How often to change your mattress depending on type and construction<\/h2>\n

Lifespan varies depending on the core material and how the mattress is constructed. Take the following ranges as a guide \u2014 deep mattresses over 24 cm<\/a> the upper limit is shifting higher because the load is distributed over a larger volume of material.<\/p>\n\n\n\n\n\n\n\n\n\n
Mattress type<\/th>\nEstimated lifespan<\/th>\nWhat wears out first<\/th>\n<\/tr>\n<\/thead>\n
Pocket springs with foam encasement<\/td>\n10\u201312 years<\/td>\nComfortable foam layers above the core<\/td>\n<\/tr>\n

The five-year warranty we offer on mattresses from our Czech production applies to the construction and materials. This does not mean that the mattress comes to an end in its sixth year \u2014 for a well-built core, that is more like the halfway point.<\/p>\n

Five signs that your mattress has reached the end of its life<\/h2>\n

One signal on its own means nothing. When two or more come together, it is time to start looking around.<\/p>\n

    \n
  1. Visible sagging where you sleep.<\/strong> The test is simple: strip the bed linen, place a straight slat or a long ruler across the bed on the mattress and look underneath it. A gap of more than two centimetres means that the core is no longer working across its entire surface.<\/li>\n
  2. You wake up feeling stiffer than the night before.<\/strong> When tension in the back, hips or shoulders goes away within an hour of moving around, it indicates a lack of support in a specific zone. Proper spinal support helps prevent this tension \u2014 a sagging mattress cannot provide it.<\/li>\n
  3. You sleep better elsewhere.<\/strong> Hotel, cottage, visiting parents. If you feel more rested after a weekend away from home, it is not due to the novelty of the environment.<\/li>\n
  4. The mattress is noisy or moves when the partner moves.<\/strong> The squeaking heralds tired springs, and the transfer of movement to the other side of the bed indicates loosened separation of the individual pocket springs.<\/li>\n
  5. Worsened breathing or itching in bed.<\/strong> Over ten years, a mattress absorbs a significant amount of moisture and becomes a home for dust mites. For more sensitive sleepers, this is noticeable first. A cover that cannot be removed and washed makes the whole situation worse.<\/li>\n<\/ol>\n

    If you only half recognise yourself in the list, you don't need to go shopping straight away. Sometimes a minor intervention is enough \u2014 and that is what the following section is about.<\/p>\n

    When is it enough to replace just a topper and when the whole mattress<\/h2>\n

    A topper is a sacrificial layer. It lies closest to the body, takes on sweat and mechanical wear, and is replaced many times more often than the mattress beneath it. That is its purpose, not a weakness.<\/p>\n

    \"Two
    Two separate mattresses on a single bed always leave a gap in the middle. A full-width topper covers it, so a couple doesn't sleep \u201eacross the crack\u201c \u2014 and it is this layer that is replaced most frequently.<\/figcaption><\/figure>\n

    The decision rule is simple:<\/p>\n
