It’s exciting to decide on investing in a brand-new mattress. Whether you’re upgrading your old mattress or filling a spare bedroom to house guests, it’s important to know how to keep your mattress in tip-top condition so you can enjoy its comfort for years to come.
A common tip to keeping your mattress in pristine condition is to purchase a mattress protector. While it may seem like an unnecessary spend, a good quality (and removable) mattress protector can help prevent any mattress stains and can be easily washed.
Another great way to care for your mattress is to ensure your mattress is placed on a base that allows it to breathe so that you know there is circulation happening to keep your mattress as fresh as possible.
Rotating your bed every so often can also help with uneven wear. Flipping and rotating your mattress can ensure the springs are being evenly used on top, bottom and either side, and can assist with prolonging the lifespan of your mattress.
You can also vacuum your mattress or further clean it to ensure any dust and extra debris is being removed from sinking deep into your mattress. Doing so will ensure your sleep environment is clean and free from any allergens.
Caring for your mattress is easy when you follow these tips! Taking the time to look after your new mattress can ensure it lasts as long as possible.
