The slammer sex position is a supported, face-down rear-entry position: the receiving partner lies on their front with a pillow under their hips, and the penetrating partner kneels behind and over them. That small lift tilts the pelvis for deeper, more targeted penetration, while the penetrating partner sets the pace. It's simple to set up and easy to adjust, but it isn't for everyone, and we'll be honest about who should skip it.
How to Do the Slammer Position: Step by Step
-
Set up the surface. A firm mattress or a sturdy couch works best. Keep two or three pillows within reach, including one firm or folded pillow for the hips.
-
The receiving partner lies face-down. Slide the firm pillow under your hips so your pelvis tilts up slightly. Rest your head on your folded arms or a flat pillow, turned to whichever side feels easiest on your neck. Legs together give a snugger, shallower feel; legs slightly apart make entry easier.
-
The penetrating partner kneels behind. Kneel straddling your partner's thighs if their legs are together, or between them if their legs are apart. Lean forward and place your hands on the bed beside their torso. Your knees and hands carry your weight, not your partner's back.
-
Enter slowly and find the angle. Start with shallow, slow strokes and let the receiving partner steer with simple words like "higher," "slower" or "stay there." Move from your hips rather than your lower back, and build speed or depth only once you've both settled in.
Why the Slammer Position Works
The hip pillow is the angle that changes everything. It tilts the receiving partner's pelvis so penetration travels toward the front wall of the vagina or rectum. For some people this may mean pressure on the G-spot area or, during anal sex, the prostate; for others it simply feels fuller. Bodies vary, so treat it as an experiment rather than a promise.
The penetrating partner gets easy control over depth and rhythm, while the receiving partner is fully supported and can relax into sensation. Lying face-down also leaves room to slip a hand or a small vibrator between their hips and the pillow for external stimulation.
3 Slammer Position Variations to Try
-
Flat Slammer: No cushion, legs closed: a gentler, snugger version for anyone who finds the full angle too intense.
-
Propped-Up Slammer: Rising onto the forearms or a stack of pillows eases the chest and ribs and makes glancing back simple; drop down again if your spine complains.
-
Edge-of-Bed Slammer: Hips at the mattress edge, feet on the floor, giver standing. This spares the giver's joints and adds leverage. If you like it, try its face-up cousin, the stand and deliver position.
Who the Slammer Position Suits (and Who Should Skip It)
The Slammer suits couples who enjoy rear-entry and deeper sensation, receivers who like to relax and be held up by the bed, and givers who like setting the pace. Height differences are easy too, since cushion thickness does the adjusting. It's one of the easier sex positions to try when you want something new without acrobatics.
Skip it or modify it if any of these apply (pregnancy is covered in the FAQ):
-
Lower back pain: The raised hips arch the spine. Use a thinner cushion or go without.
-
Neck stiffness: Keeping the head turned one way can strain it. Alternate sides or try the propped-up variation.
-
Sore knees or wrists: Kneeling and leaning load both for the giver. Add padding or try the standing variation.
-
Pain with deep penetration: Conditions such as endometriosis or pelvic floor pain can make this angle uncomfortable. Choose a gentler variation or another position.
Slammer Comfort, Safety and Consent
Use lube generously. It's essential for anal sex, because the anus doesn't produce its own lubrication. Avoid oil-based lube with latex condoms and silicone lube with silicone toys.
Face-down positions limit eye contact, so agree on the version you're trying beforehand and set a clear stop signal that works without words, such as two taps on the bed. Check in verbally as you go. Sharp pain, numbness or cramping means stop and reposition rather than push through, and either partner can pause or stop at any point.
Slammer Position FAQ
Is the slammer a good sex position for beginners?
Mostly yes, because it needs little flexibility or strength and the receiving partner is fully supported. The one thing to take slowly is depth, since the hip-pillow angle can feel intense at first. Many couples start with the Flat Slammer and add the pillow once they're comfortable.
Can you do the slammer position while pregnant?
Early on it may be fine, but lying face-down gets uncomfortable as the bump grows. Pressure on the belly and breasts is the usual reason people stop. Side-lying spooning is a common, comfortable swap, and your midwife or doctor can advise on anything specific to your pregnancy.
What should we do if the slammer feels too deep or hurts?
Pause, then take the hip pillow out and have the receiving partner close their legs. The penetrating partner can switch from long strokes to rocking or grinding, or wear a soft bumper ring that limits depth. Pain that keeps coming back across positions is worth raising with a doctor or pelvic floor physiotherapist.
How is the slammer different from prone bone, the piledriver or the Grand Slam?
The slammer is the low-effort, fully supported option. Prone bone is very similar, but often without the hip pillow and with the giver lying closer on top. The piledriver is an advanced inversion where the receiver's hips are lifted above their head and weight rests on the shoulders, which carries real neck risk. Position names aren't standardized, so "slammer," "Grand Slam" or "sledgehammer" can mean different setups on different sites; this guide describes the common face-down, hip-propped version.
