Why this shape
Modular pieces leave a gap under the hips; the buttocks are not the load-bearing surface.
Three pieces make a center-opening sleeping pillow. The U-shaped wedge takes the thighs. A smaller piece takes the low back. The middle stays empty.
If you close the gap, you are back on a surface. The listing image that says you set the height means: move pieces, do not fill the hole.
High-density foam. Plush velvet zip covers, machine wash. Dotted non-slip bases. Side straps hold a stacked wedge.
The fourth piece is the curved cushion — a toilet pad — and the center block is a footrest. Three pieces also build a continuous ramp for legs or a back rest.
Stacked bed pillows sink and close the hole you need under the hips.
Listing uses: a supportive sleeping setup after Brazilian Butt Lift surgery; a wedge for leg elevation or back support; a curved BBL toilet-seat cushion; a center-block footrest.
This is not the full-length extra-thick 9-piece V-bed, and it is not the GAB 5-piece set. Same idea — a gap under the hips — different kits.
A pile of pillows has no fixed opening. By morning it is a lump under the buttocks — the surface the protocols say not to rest on. These pieces have a cutout and a strap. You leave the gap.
What clinicians say
Written BBL protocols keep the buttocks from being the surface you rest on.
The American Society of Plastic Surgeons: after fat grafting to the buttocks, avoid prolonged sitting (about two weeks; some surgeons longer); sleep face down or on your side; if you sit, put the cushion under the hamstrings so the buttocks are raised.
Scripps Health: for about two weeks, do not sit, lie, or put pressure directly on the buttocks; sleep on the stomach. Later sitting, if the surgeon allows it, uses a pillow under the thighs. Unrestricted sitting is described at about eight weeks.
Chicago Breast and Body (Dr. Truong): do not sit directly on the buttocks or lie on your back for 4 weeks; sleep on the stomach. That written order forbids back-lying. This set is a back-lying geometry plus a toilet pad. Use the bed setup only if your surgeon allows that position.

Excerpt of the recovery page, not the full ASPS procedure guide.
You will be asked to avoid prolonged sitting for about two weeks (some surgeons prefer longer). This is very important because prolonged sitting will damage the fat.
You will also be encouraged to sleep face down or on your side. When you do have to sit, you will have to use a pillow or cushion placed behind the legs (hamstring muscles) to help raise the buttocks, avoiding pressure onto the fat grafts.

Following the procedure, you should be able to return to light daily activity and work within 10 to 14 days. However, you will not be able sit, lie down or put pressure directly on your buttocks for about two weeks. You’ll need to sleep on your stomach, and either lie on your stomach, kneel or stand during daily activity.
After a couple of weeks, your surgeon will give you the green light to sit in a modified position with a supportive “donut” seat or pillow under your thighs to prevent pressure on your buttocks. Generally, you can return to sitting without restrictions about eight weeks after the procedure.

After surgery
What to skip after surgery
- Do not sit, lie, or put pressure directly on the buttocks when that is the order (ASPS; Scripps Health).
- Some written protocols forbid back-lying for weeks (Chicago Breast and Body: 4 weeks). Use the bed setup only if your surgeon allows that position.
- Do not push the pieces together so the buttocks rest on foam. Leave the gap under the hips.
