Studies have shown that adults need 7-8 hours of sleep daily for the body to continue its proper functioning. However, for many people, their body isn't always in good shape when they wake up from sleep – which shouldn’t be. This is mostly because of the state of the mattress.

A bad mattress causes body, back or neck pain and should be changed as soon as possible, before it causes more damage.

Purchasing a mattress seems like a big deal to most people, because they feel they have to exhaust all their money before they can get a very good mattress. This is very untrue.

You don't have to break your bank account to purchase a mattress and below are 6 nifty ways to save money when buying one.

1. Negotiate

Purchasing a mattress could really take up a large sum of your money if you're not skilled at negotiating.

Try negotiating the price with the salesman, see if you could get a bit of the price cut down. You can find out how much the store discounts the mattresses on sale, just so you know how to negotiate reasonably.

2. Freebies

After you've been told the price of the mattress at the store, ask if there are any freebies coming with the mattress if purchased. Could be free pillows, a mattress pad or even free delivery.

There's no harm in asking, if you get these freebies, you'll be able to save some money on the delivery, pillows or mattress pads.

3. Sales

Another effective way of saving money when buying a mattress is by purchasing it on sales.

When stores put out mattresses on sales, they cut a large percentage off the actual price. With this you'll be able to get the mattress of your choice at a cheaper price and even save some money.

4. Check the warranty

Long warranties on mattresses don't mean anything, so don't fall for it. Most times the warranties that come with mattresses only cover defects, not wear and tear. This means you'll have to spend more money buying a new one if your mattress has any wear or tear.

Warranties also differ and have various requirements. Some warranties state that whatever defect affects the mattress has to be over one inch, and a personnel will be sent over to measure it with a ruler.

It's not as simple as it seems so crosscheck warranties as much as possible.

5. Buy used mattress

This might not be a comfortable option, but it really does work for most people on budget.

Used mattresses aren't as bad as they sound; sometimes they are even better than the new ones. Although it has no specific warranty, you know it must be really good if it's still in good shape after being used.

Purchasing used mattresses ensures you save lots of money and also get the mattress of your choice.

6. Discounts

Lots of mattress stores offer discounts on the mattresses in the store so be on the lookout.

If there's no visible sign of a discount, you can approach any of the sales representatives and ask if there's any discount program. This way you get to save some money and also get the mattress of your choice.

Buying a mattress doesn't have to mean breaking your account. The 6 ways above will guide you in the purchase process and help you save some money.
