Premium Fabric Six-Piece Recovery System: A wedge pillow set for after surgery you build yourself: a steeper angle the first weeks, less height as recovery goes on, or split the stack to raise your legs. Rest the back stack against a headboard or wall. For Shoulder and Post-Surgery Sleeping: A bed wedge pillow post surgery setup for sleeping on your back at an incline after rotator cuff or shoulder surgery. Six modules let you start upright and flatten the stack over the weeks. Ask your surgeon about the angle. Unpack 48 to 72 Hours Before Surgery: Ships vacuum-compressed and takes 48 to 72 hours to expand, so open the box before the day you need it. Inside: six foam pieces, a gel pack, two compression bags, and non-slip covers made with OEKO-TEX certified fabrics. A Recliner Alternative in the Bed You Own: Stack the pieces into a semi-reclined setup instead of buying a recliner or an adjustable bed. After recovery they carry on for reading, TV or working from bed. Backed by a 1 year warranty, 2 years with registration. Built Piece by Piece: Head and lumbar pillows are solid memory foam; back, knee and leg wedges carry a memory foam layer over an aloe vera infused high-density core. Knee and leg fasten with hook-and-loop tabs, and a strap links head to back. Covers unzip. 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 Lunix LX13 Six-Piece Wedge Pillow Set. Q: Do the pieces slide apart during the night? The knee and leg pieces fasten with hook-and-loop tabs, and an elastic band strap links the head pillow to the back wedge. The lumbar wedge has no fastener. Steadiness depends on the build: rest the back stack against a headboard or wall, and use fewer pieces if you move a lot at night. Q: Is the whole set memory foam? No. Memory foam is used where you make contact; support foam carries the volume. Head and lumbar pillows are solid memory foam; the back, knee and leg wedges carry a memory foam layer of about 2.5 cm (1 in) over a high-density core. Q: How firm is it? Firmness differs by design. The head and lumbar pillows are the softer, all-memory-foam ones. The larger wedges are firmer because a support core carries the weight, so if you want a soft sleeping surface they will read as firm. Q: When should I open the box if my surgery is next week? Open it 48 to 72 hours before the day you need it. It ships vacuum-compressed and looks flat at first. That window lets the foam expand and leaves time to check the pieces while you are still on your feet. Q: How do I know which piece goes where? Start with three: the back wedge, the head pillow and the leg wedge. Add the lumbar, knee and base pieces as your recovery calls for them. You do not have to use all six at once. Ask your surgeon about the angle. Q: Does it smell of chemicals when I open it? Compressed foam can carry a faint new-material scent. The covers are made with OEKO-TEX certified fabrics, and airing the pieces during the expansion window handles most of it. Q: Will it take over the whole bed? It is large: assembled, it covers a good part of one side of the bed. Two compression bags are included for the pieces you are not using, but plan for real closet space: foam takes room even compressed, and the bags are for storage rather than long-term vacuum.
