To ensure that your mattress remains in pristine condition for years to come, we’ve compiled the following expert recommendations:

Say No to Bending and Jumping

While it might be tempting to use your mattress as a makeshift trampoline, bending or jumping on it can compromise its structural integrity. This can lead to premature sagging and reduce the effectiveness of its support features.

Prioritise Linen Hygiene

A clean bed is a happy bed. We recommend washing your bed sheets, pillowcases, and other linen every one to two weeks. This not only keeps your sleeping environment fresh but also helps to minimise the accumulation of dust mites and allergens.

Invest in a Quality Mattress Protector

A mattress protector acts as a safeguard against accidental spills, stains, and even allergens. By using one, you’re not just keeping your mattress clean; you’re also preserving its aesthetic appearance and overall longevity.

Daily Aeration is Key

Your mattress needs to breathe just like you do. Make it a habit to pull back the covers each morning and let your mattress air out for a bit. This simple act helps to dissipate moisture, reduce odors, and maintain a more hygienic sleep surface.

Rotation Rituals for Single-Sided Mattresses

If your mattress is single-sided, it’s crucial to rotate it from head to toe. For the first three months, make this a weekly routine. After that initial period, shifting to a monthly rotation will suffice. This practice helps to ensure even wear and tear, thereby extending the lifespan of your mattress.

Prompt Attention to Spills

Accidents happen, but quick action can prevent a small spill from becoming a big problem. If you do experience a spill, clean it up immediately using warm, soapy water and a soft cloth. This will help to prevent the liquid from seeping deep into the mattress, where it could cause long-term damage.
