Q4: What guarantee does a Flex mattress have?

To demand the use of the guarantee, you must have with you the purchase invoice of the mattress and thus proceed with the total replacement of the product or its repair. The latter could contemplate the displacement of the technical service.

You must be very attentive to the things for which you could lose your guarantee. For example, tampering by someone other than the Flex service or failure to follow any of the maintenance guidelines in the manual.

Q5: How to clean a Flex mattress?

When you analyzed and made the decision to buy a Flex mattress, you looked at the high technology that it offers both in its upholstery fabrics and in the core of the mattress. Washing it with water, soap and exposing it to the sun is not an option that will not cause damage to its material. So the first recommendation is to protect it with a mattress cover.

Each mattress is different in materials, therefore, you must adhere to the cleaning instructions on its label or the recommendations given by the Flex technical service.

How to use a Flex mattress

If you have already purchased one of the best mattresses on the market, then it is time to release it. Your body and especially your back will soon see the benefits of a night’s sleep on a Flex mattress. Although it is known that its durability will not be indefinite, giving it a correct use will extend its useful life.

good support

Whether you have a slatted bed base, a plank, a box spring or a bed frame for him, placing him on a good support is very important. First, make sure the base surface doesn’t have any sharp edges that could break or tear the mattress upholstery.

Similarly, you must ensure the stability and strength of both the surface and the legs of the base. If not, it is preferable that you wait to install it until you get the ideal support. An inadequate surface can allow the inappropriate sinking of some parts, and weak legs could cause falls when sitting or lying on the mattress.

Getting used to your mattress

Believe it or not, your mattress and you will need some time to adapt, just as if it were new shoes. The Flex brand technology allows the progressive adaptation of the mattress to the weight and shape of your body. This manufacturer notes that it takes two to four weeks for the mattress materials to settle, mold, and mark what Flex calls your body’s imprint.

This time will be just as important for you to get used to the type of firmness with which you have chosen the mattress, especially if you purchased one of superior firmness or with Multielastic springs. If you bought a Bed in Box, when you take it out of the box and unroll it, you should stretch it gently and leave it for at least a day to take its shape.

mattress care

The upholstery of Flex mattresses usually has technology and fabrics with very nice designs that must be taken care of. The ideal is to put a mattress protector on it and, even better, if it is resistant to liquids. Remember that a mattress is not an element that can get wet and exposed to the sun’s rays without consequences for the core and its components.

Unless it is a rolling mattress, avoid folding it, and as we know that it is very tempting, keep children away from jumping and playing on the mattress. For cleaning recommendations, you must read its instruction manual that will indicate how to do it depending on its materials and fabrics.

turn the mattress

In general, a mattress should be turned every six months to ensure even wear on all parts of the mattress. In the specific case of Flex, this brand recommends doing it monthly during the first six months of using the mattress. After this period, he suggests turning it over every three months, taking turns on its sides. For example, in January it turns on its side, in April it turns not only to the opposite side, but also its position from bottom to top.
