We always have box springs of all sizes in stock - ready to be delivered to the Greater Ann Arbor area; free of charge! The standard height of our foundations is 9 Inches but we may have a 5.5" Low Profile Option that is often readily available. (Call to inquire). If space is an issue, you may need or want a split (2 piece) box spring. (See Below For Pricing). Our Box Springs are a neutral color and match nearly any decor. (See Photos).
