Positioning pillows come in three main shapes: the wedge, the ramp, and the curved wedge. A wedge gives a simple angled lift, a ramp offers a longer gradual incline, and a curved wedge cradles the body along a concave arc. For most couples the curved wedge feels the most natural, because it supports the body instead of propping it on a flat slope.
The Classic Wedge
A basic wedge is a triangular block: thick at one end, thin at the other, with flat faces. It delivers a clear, firm lift and is easy to understand. The limitation is that its flat top places the body on a single plane, so the point of contact can feel like a hard edge rather than a supportive surface. Cheaper foam wedges also tend to compress unevenly over time.
Wedges are fine for occasional propping, but for sustained comfort during closeness, that flat surface is where many couples feel the design showing its age.
The Ramp
A ramp is a longer, lower-angle incline. It spreads the lift over more of the body and can feel gentler, which suits people who want a subtle rise. The trade-off is footprint and storage: ramps are larger and bulkier, and their shallow angle may not give enough lift where a couple actually needs it. They also take up more of the bed, which matters in smaller spaces.
The Curved Wedge
A curved wedge, like the Sweet Spot Pillow, uses a double concave arc rather than flat faces. The concave shape cradles the lower back and hips, distributing pressure along a curve so the support feels like it fits the body. Paired with high-density memory foam (around 50 kg per cubic meter), it holds its angle at a comfortable 25 to 30 degrees and keeps its shape for three to five years. The honest trade-off is price: a shaped, high-density wedge costs more than a basic foam block, but it is the difference between propping and truly supporting.

Frequently Asked Questions
What is the difference between a wedge and a curved wedge?
A wedge has flat faces and gives a firm lift on a single plane. A curved wedge uses a concave arc that cradles the lower back and hips, so support feels contoured to the body rather than propped on a hard edge.
Which shape is best for couples?
Most couples prefer a curved wedge for daily comfort, because its concave shape distributes pressure and holds a 25 to 30 degree angle. Ramps suit those wanting a subtle rise, and basic wedges suit occasional propping.
Does shape affect how long the pillow lasts?
Shape plus foam quality both matter. A curved wedge in high-density memory foam keeps its arc for three to five years, while cheap flat foam blocks tend to compress unevenly sooner.
