Foundation
Give your mattress the support it needs with foundations and box springs from Jax Mattress in Jacksonville, FL. A proper foundation is essential for extending the life of your mattress, ensuring even weight distribution, and maintaining the support your mattress was designed to provide. Our foundations come in standard sizes to match your bed frame and mattress — Twin, Twin XL, Full, Queen, King, and California King. If you're replacing an old box spring, a modern foundation offers a firmer, more stable base without the bounce of traditional coil box springs. Low-profile foundations are available for beds where you want a lower overall mattress height. Not sure if you need a foundation? Check your mattress warranty — many manufacturers require a proper foundation to keep your warranty valid. Our team can help you choose the right base for your mattress type and bed frame. Visit our showroom in Jacksonville or shop online. Delivery available. Financing options available.
