Mattress Sale 2020

Of course the reason you purchase a new mattress is to sleep better and wake up more refreshed. There are many factors that can effect sleep.

Keeping a sleep schedule and going to bed around the same time every night can signal to your body that it is time to rejuvenate.

Keeping the bedroom dark and cool will also signal to your body that it's time for sleep.

Many couples can be disturbed by each other moving around throughout the night. It's important to have a bed that is both large enough to minimize movement, but also a support structure that is designed to reduce motion transfer.Some models do a better job than others. For example, pocketed coils do a better job than classic innerspring coils at reducing motion transfer.

Many models come with a warranty, which can be voided if there are any stains or soiling on the mattress, which is one reason why it's important to use a protector. Keeping a clean and sanitary sleeping environment will contribute towards better health and wellness.

You can reduce allergens in the bedroom by using a HEPA air filter, vacuuming regularly, keeping pets out of the bedroom, and washing bedding.
