Frequently asked questions
What is a full-length mattress wedge used for?
A full-length mattress wedge elevates the entire sleep surface, helping with acid reflux, snoring, and circulation issues. It provides a consistent incline that supports spinal alignment, unlike smaller wedges that only lift the upper body.
How do I choose the right height for a full-length wedge?
Consider your sleep position and needs. Lower heights (5-6 inches) work for mild reflux or snoring, while higher inclines (7-12 inches) suit severe reflux or breathing issues. Side sleepers may prefer lower heights to avoid hip strain.
Are full-length mattress wedges washable?
Most wedges have removable, machine-washable covers, but always check the product specs. Some budget models have non-removable covers that require spot cleaning. Look for OEKO-TEX certified covers for safety.
Can a full-length wedge help with back pain?
Yes, by maintaining spinal alignment, it can reduce lower back pain, especially for those who sleep on their back. However, stomach sleepers may experience increased discomfort due to the incline.
How long do full-length mattress wedges last?
With proper care, high-density foam wedges last 3-5 years. Hybrid models with coils may last longer. Look for CertiPUR-US certification and check warranty details, typically 1-5 years.
