When purchasing a new mattress it’s important to know if you need a new box spring as well. Why?Because box springs have changed in the past decade and new box springs really don’t act as a spring. Instead, they act basically like a slat system that helps keep the bed elevated making it easier to get in and out of. Below is a picture of an older box spring for illustration purposes.
As you can see in the picture these heavy gauge wires were designed to have some give so that they would collapse slightly as you laid down on your mattress. The effect would be having a little more bounce and spring to your mattress. The old box springs were designed to work with the spring systems and this was taken into account.
Today, there are so many different types of mattresses that it doesn’t make sense to sell these types of box springs. Below is a picture of a more modern box spring.
Modern box springs are basically wooden slats made into a box which also has a cover. You can buy these on Amazon for under $200 and they come in a box. They don’t take long to setup and will give your mattress the support it needs.
However, you really don’t need a box spring with a mattress. Some companies prefer that you put your mattress on slats or a box spring to help the mattress breathe but it’s certainly not necessary. For a little more you can buy an entire bed with a slat system from Zinus. Here’s my review of the Zinus platform bed which is very sturdy and will arrive in a box as well.
If you are wondering if you need a box spring or not, a good rule of thumb is that if the box spring is older than 10 years, it probably needs replacing. You can also tell just by pushing on it. If it is springy, they get rid of it.
I would not feel obligated to buy the box spring from the same company where you bought your mattress either. There is a perception that if you don’t, you will void your warranty. Make sure this is really the case though before you commit to buying a new box spring. Chances are you can find a better price on Amazon or you may just want to go with a slat system instead.
