Hollow center. Gel over foam. The midline of the pelvis is the gap, not the seat.

Why this shape
The hollow center is the point: the sacrum and tailbone sit in the gap, not on the foam.
Two pads, straps between them. Slide the gap. Listing images label a maximum of about 3.5 in. Use both pieces together, or as two separate pads under the hips.
Thicker at the back than the front: 3.94 in and 2.36 in on the listing diagram. Gel pads over memory foam. Polyester zip cover, machine wash. High-traction bottom so the pad stays on a sheet or a chair.
A flat pillow still puts the tailbone on foam. A one-piece donut has a fixed hole.
Bed or chair. After surgery or after birth, if the order is: keep that bony midline from being the seat. Listing images label a fit of 100–220 lb and hip circumference 35–50 in.
Blue or Gray. Same pad.
Two pieces let you set the gap. A high-traction bottom stays on the sheet instead of sliding into a pile.
What clinicians say
Pressure redistribution is a positioning problem. A pad does not replace turning.
The 2026 NPIAP / EPUAP / PPPIA international guideline, Repositioning and Mobilization chapter: extended lying or sitting on one part of the body, without redistributing the pressure, deforms tissue.
The same chapter: reposition so you offload pressure points and redistribute load. Positioning devices can hold a position or lift a body part off the surface. No support surface entirely replaces repositioning.
This cushion is that kind of device: a hollow so the sacral midline is not the contact. It is not a turning schedule. It is not a treatment.

Excerpt from the introduction and good-practice statements R1–R2, not the full chapter.
The underlying cause of pressure injuries (PIs) is multifaceted; however, by definition, pressure injuries cannot form without mechanical loading acting on the tissue. Extended periods of lying or sitting on a particular part of the body without redistributing the pressure leads to deformation of tissues and, ultimately if damage thresholds are exceeded, tissue damage in the form of a PI.
R1: It is good practice to reposition individuals with or at risk of pressure injuries regardless of the type of pressure redistribution full body support surface being used. … However, no support surface can entirely replace repositioning.
R2: It is good practice to reposition the individual in such a way that optimal offloading of pressure points and maximum redistribution of pressure are achieved.
Use positioning devices. These devices can assist in maintaining positioning, be used to elevate parts of the body off the support surface, and can promote body symmetry, posture and comfort.

After surgery
What to skip after surgery
- Do not treat this pad as a turning schedule. The 2026 NPIAP / EPUAP / PPPIA guideline: no support surface entirely replaces repositioning.
- Do not leave one part of the body loaded without redistributing the pressure — that is the positioning problem the guideline describes.
FAQ
FAQ
- What is a sacral-coccyx cushion?
- A two-piece foam pad with a hollow center. You sit or lie so the sacrum and tailbone rest in the gap, not on the foam. Blue and Gray on Amazon.
- How do the two pieces work?
- Two pads with straps. Slide them to set the center gap — listing images label a maximum of about 3.5 in. Use them together or as two separate pads.
- Can I use it in a chair and in bed?
- Yes. High-traction bottom for a bed or a chair. Same hollow center either way.
- What is the difference between Blue and Gray?
- Color only. Same two-piece pad, same hollow center, same gel-over-foam build.
