The 7 Best Liberator Wedge Positions, Tried on a 27° Pillow. Here's What Changes When the Wedge Stops Sliding…

Short answer: The classic Liberator Wedge positions, like the face-down wedge, the hips-up wedge and the bed-edge wedge, all work on the WildNightX Pillow too. It has the same 27° slope, stands 11.8 inches tall in one piece, and sits on a silicone grip base, so the wedge stops sliding.

You've seen the Liberator Wedge positions chart. One foam wedge, a few simple drawings, and it all looks so easy.

Then you try it at home. The wedge creeps across the sheets. Someone's knees start to ache. You stop to fix it, and the mood fades. One Liberator reviewer described what a good wedge saves you: "the extra effort you have to put in and the strain on your joints."

Credit where it's due. Liberator helped make the sex wedge popular, and many position charts are drawn on their shapes. So below are 7 classic wedge positions, and how each one works on the WildNightX Pillow, a 27° memory foam wedge with a silicone grip base.

For each one, we cover where the wedge goes on a classic wedge, what changes on the 27° pillow, what it saves your body, and one quick tip.

Why wedges made positions easier, according to a sex therapist

"Historically, sex pillows were primarily marketed toward older folks who had joint issues or bad knees because they made sex positions more comfortable"

Emily Jamea, PhD, a sex therapist and host of the Love & Libido podcast, speaking to Women's Health

1. The Face-Down Wedge

Restful, simple, and a great first try on any wedge.

On a classic wedge: she lies face down with the wedge under her hips. Liberator lists its Wedge at 7 inches tall.

On the 27° pillow: same spot, a little more lift. The pillow stands 11.8 inches tall, so her hips sit higher without a second piece.

Easier on: wrists and knees. She rests on the bed and the foam instead of holding herself up.

Try this: center her hips over the slope. The grip base keeps the pillow in place as you both move.

2. The Hips-Up Wedge

The position the wedge is best known for. Face to face, and easy to hold.

On a classic wedge: the thick end goes under her hips, and the slope runs toward her partner.

On the 27° pillow: same placement. Her lower back rests on the curve, and the angle stays the same from start to finish because the 60 kg/m³ foam doesn't sink.

Easier on: her lower back. No arching, no pushing up on her heels.

Try this: let the foam do the work. As sex educator Alicia Sinclair told Cosmopolitan, "They hold a position for you so you don't have to burn a hundred calories just staying propped up on your elbows."

3. The Bed-Edge Wedge

The go-to when kneeling on the mattress is hard on the knees.

On a classic wedge: the wedge sits at the edge of the mattress under her hips while she lies back. Her partner stands on the floor.

On the 27° pillow: this is where the grip base matters most. At the edge, a wedge that slides ends up on the floor. This one stays put.

Easier on: his knees. He stands instead of kneeling, and the lift brings her closer to his height.

Try this: on a low bed, he bends his knees a little and widens his stance.

4. The Wedge-and-Ramp Combo, in One Piece

Liberator also sells a longer Ramp as a separate piece, and couples often ask about the wedge and ramp combo for extra height.

On a classic wedge: couples pair or stack the two pieces for more height.

On the 27° pillow: one piece does both jobs. She kneels and rests her upper body on the high end, which stands 11.8 inches tall.

Easier on: arms and shoulders. She leans on the foam instead of holding herself up.

Try this: rest her arms and head on the small cushion that sits on top of the pillow.

5. The Under-Him Wedge

Turn the wedge around. This time it goes under him.

On a classic wedge: he lies back with the thick end under his hips, and she sits on top facing him.

On the 27° pillow: same idea. The contoured foam cradles his lower back, so he can relax while she sets the pace.

Easier on: her thighs. The lift raises his hips a little, so she does less work to find a comfortable angle.

Try this: treat it as an experiment night. Marriage and family therapist Sara Sloan told Cosmopolitan that sex pillows are "a must-have for any couple wanting to explore new positions."

6. The Side-Lying Wedge

The slow, lazy-morning option.

On a classic wedge: you both lie on your sides, and the wedge goes under her hips to tilt them slightly.

On the 27° pillow: the tilt holds steady, and the grip base keeps the pillow under her instead of drifting away.

Easier on: everyone. Nobody carries anybody's weight. If lying on your side bothers your back, skip this one.

Try this: keep the pillow centered under her hips and the pace gentle.

7. The Wedge Recliner

A wedge isn't only for under the hips. Flip it, and it becomes a backrest.

On a classic wedge: it props him up a little behind his back while she sits facing him.

On the 27° pillow: the chair-like curve is built in, so it works as a real backrest on its own.

Easier on: his neck and shoulders. He reclines instead of holding himself up, and both hands stay free.

Try this: keep it close and slow. Next morning, the same pillow makes a comfy backrest for reading in bed.

Liberator Wedge or the WildNightX Pillow? Both use a 27° slope, and both are firm foam. One Liberator reviewer praised that it "won't compress into a flat pancake like a pillow." Liberator is a long-running brand. Its Wedge lists at 14 × 24 × 7 inches with an easy-wipe cover, for $120, and the Ramp is a separate piece. The WildNightX Pillow is one 23.6 × 15.7 × 11.8 inch piece with a chair-like back, a silicone grip base and a washable linen cover, and it looks like a throw pillow on your bed.

To be fair: the Liberator Wedge has wins of its own. It's a long-running brand, its cover wipes clean, you can add the Ramp later, and it costs a little less ($120). The WildNightX comes in one size and one color (gray), its linen cover is only lightly water-resistant, and the foam core doesn't wash. Pick the Liberator if you want a wipe-clean wedge and don't mind storing it. Pick the WildNightX if you want one that stays on the bed.
