Mattress Center Support Systems

Prevents Sagging, Squeaking, Shifting, Bowing & Cracking

 

Center Supports add essential mattress support and are available for Twin, Full, Queen, King or Calif. King size bed frames/rails.

 

Unknown to most consumers, mattress manufacturers' warranties may be void if sufficient center support is not provided with additional cross supports and legs for complete stability.

That "free frame" you received when you purchased your mattress may be doing your mattress harm. Most likely, you received a cheap promotional frame which offers no center support and less than average weight load capacity.
