Technically any foundation or box spring will work. It won't meet the current federal fire code but as long as it is the same size it should do fine. But you may also be voiding the manufacturer's warranty if you are not using a box spring made for that bed.

Possible to use another foundation: yes

Recommended because of fire code and mfg warranty: no

Anton is right. If your on a budget, any sturdy boxspring or foundation should work fine. Depending on your weight and what frame you will be putting your mattress set into. Make sure the foundation is sturdy when you press your weight on it and there are no squeaking or cracking sounds evident. Also, it's good to lay a straight edge across the foundation to check for any bowing or slanted surfaces.

If your mattress is 1 sided, your box spring will have to be a platform. A firm foundation. In a full size, it should run between $80-$120 depending on where you go. I recommend trying to find a store that sells an off brand mattress brand if money is tight. That will save you some money and still work just fine. On the bottom end $$-wise, just try to be gentler on it. It may be easier to make squeak in the long haul.

Many beds today use a foundation not a box spring and it provides ample support and is very affordable. While it won't meet Federal fire regulations it has passed all necessary testing, just not with your particular mattress. You should be able to buy a full size foundation for $100 at any good sleep shop. Just call around.

Or even a platform base, which tends to be easier to move and can outlast a box spring.

Sleep Well!

I would suggest finding a smaller retail store and Not a BIG NAME STORE. You should get a full foundation for $75-$100. I would recommend getting a foundation rather than a box spring.
