Four-Piece Recovery System, FSA: Arrange four separate memory-foam wedges into an upright or reclined setup for rest and elevation while recovering after surgery, then break them back down to reconfigure for your body and your bed. Adjustable Elevation for Upper Body, Back, and Legs: Reconfigure the wedges to raise the upper body for sleeping more upright, or to elevate the legs, adapting the incline to your bed and your recovery routine. Lock-Tight Stability Design: Integrated Velcro connectors and a non-slip cover base are designed to help the pieces stay connected and reduce shifting during the night, for a steadier setup than loose stacked wedges. Medium-Firm 40D + 25D Foam: Made with 40D memory foam over a 25D high-density support core at a defined Medium-Firm support level, so the wedges keep a stable incline for upright rest and leg elevation. OEKO-TEX Certified Aloe-Infused Fabric, Removable Washable Cover: The removable cover is machine washable and made from OEKO-TEX certified, aloe vera-infused fabric selected for a soft, low-odor surface. Wipe the foam clean and air dry. Complete Recovery Set and Lifetime Warranty: Includes a reusable hot/cold gel pack for soothing comfort, vacuum storage bag, all backed by dedicated customer support. About the LX5 4-Piece Orthopedic Bed Wedge Pillow Set. Q: Do the four pieces stay together, or do they slide apart during the night? The wedges connect with integrated Velcro and sit on a non-slip cover base, which is designed to help them stay together and reduce shifting while you rest. On any modular set some movement is possible, so the design goal is a steadier setup than loose stacked pillows, not a locked-in-place guarantee. Q: How firm is the foam, and will I sink into it? It uses 40D memory foam over a 25D high-density support core at a defined Medium-Firm support level. That is a firmer, more supportive feel than a soft plush pillow; it is meant to hold a stable incline rather than let you sink in. If you prefer a very soft surface, this set will feel firm. Q: Is it really four separate pieces, and how do they reconfigure? Yes, it is four individual foam pieces, not one molded block. You arrange them into an upright back-rest incline, a reclined elevation, or a leg-elevation layout, and rearrange them as your needs change. Q: Is the cover removable and machine washable? Yes. The cover is removable and machine washable and made from OEKO-TEX certified fabric. For the foam itself, wipe the surface clean and let it air dry away from direct sunlight. Q: Can I use it for elevation and rest after surgery? Many customers use it to sit up or sleep more upright and to elevate the upper body or legs during recovery after surgery. It provides adjustable elevation and support; it is a comfort and positioning product, not a medical device, so follow your care provider's guidance for your recovery. Q: Will it work for a smaller or petite frame? Because it is four reconfigurable pieces, you can build a smaller or lower incline rather than being locked to one fixed height. Some customers with a smaller frame find the full stack tall, so starting with fewer pieces or a lower angle is the better fit; the pieces let you scale it down.
