The Coffin Grinder – Tentacle Strap-Down Grinder
Some grinders are a flat pad, some are a simple raised mound, and both do the job well. The Coffin Grinder went a different way about it and we'll happily admit we got carried away. A tentacle hauls itself over a coffin lid, thick through the middle and tapering as it goes and that curve is the thing you ride. Rock your hips and your body travels along it, the pressure changing with every inch.
It's a sculpture that happens to get you off. The whole scene is cast as a single piece, tentacle, coffin, wet stone and all, and it works beautifully with no batteries involved at all. Add the bullet upgrade and we build a cavity into the base during casting, so a 7-speed bullet sits just underneath the tentacle and pushes vibration up through it.
If a tentacle draped over a coffin feels like a lot for a first grinder, don't let it put you off. There's nothing to insert, nothing to figure out and nothing that happens unless you make it happen. You sit on it and move. That's the whole thing.

▶ Why You'll Love It
- The curve of the tentacle itself → the shape is the sensation, not a pattern printed onto a flat surface
- Tendrils and ridges between the suckers → finer texture layered over that curve as you pass across it
- Sculpted suckers down the length → the part everyone stares at in the photos, and a fair bit of the reason you'll want it on display
- Straps down to almost anything → a pillow, a chair, a partner's thigh and it holds that position
- Optional 7-speed bullet cavity → vibration sits right under the texture rather than off to one side
- Three firmness options → pick how much give you want under your weight
- Nothing to charge, nothing to break → the only power source is you
- Handmade platinum-cured silicone → body-safe, non-porous and built to last
- Sculpted as a full scene → the kind of thing you'd happily leave out on a shelf in October
▶ What It Feels Like
- Sturdy. There's a real shape under you, something to press into rather than skim across
- The pressure builds as you rock forward into the thick of the tentacle, then eases off as it tapers away
- Ridges and tendrils catch as you pass over them, fine detail layered on top of the bigger shape
- Every bit of it comes from your rhythm, so it goes where you take it and stops when you stop
- Slow rocking feels like teasing. Leaning your weight in changes it completely
- With the bullet in, vibration rises up through the silicone and meets you in the middle
- Grounded and steady, you're riding it, not gripping it
▶ Is This Toy Right For You?
Great For
- People who prefer grinding and rocking over thrusting
- Anyone who wants something with real shape to grind against, not just a textured pad
- Those who want pressure controlled by their own body weight
- Hands-free play with a stable, strap-down setup
Also Good For
- First-time grinder users, it's about as intuitive as toys get
- Experienced users who want texture without vibration
- Anyone who wants the option of vibration without committing to it
- Partnered use, strapped to a thigh or cushion
- Anyone whose favourite month is October
Might Not Be Ideal If
- You want penetration, there's nothing insertable here

▶ Colours & Custom Options
Godemiche toys are made to order, allowing you to choose from a wide range of colour combinations.
You can select anything from simple single colours to multi-colour designs, fades and highlights depending on the product options available.
The main product image shows the Signature colourway for this design. Signature colours are specific to each toy and are the version you'll see photographed in the listing, unless stated otherwise.
If colour choice isn't important to you, you can also select Godemiche Purple, our classic house colour or choose Surprise Me and let us pick a colour combination for you. Surprise Me colours are chosen from our available silicone pigments and often result in unique combinations.
With dozens of colour possibilities, you can create a toy that feels uniquely yours.
Because each piece is handmade, colour placement and blending may vary slightly from one toy to the next. This is a natural part of the process and part of what makes every piece individual.
If you'd like to see examples of how different colour styles look, you can explore our full Godemiche Colour Guide.
▶ Firmness Options
This toy is available in three silicone firmness levels:
Extra Soft
The most give. Squashes easily under your weight and cushions the texture, so it's the gentlest of the three.
Soft
Still plenty of give, but the tentacle holds its shape more, so the texture comes through more clearly.
Medium
Very firm. Only pick this one if you know you like really firm clitoral stimulation, it's a lot for most people and there's no softening it once it's poured.
Not sure? Go Extra Soft or Soft.
If you're grinding hard or a partner is adding pressure on top, Extra Soft is the safer bet.
▶ How To Use
1. If you've gone for the bullet upgrade, slide the bullet into the cavity in the base first, before you strap anything down. It can be a snug fit the first time, that's intentional, it stops it rattling around.
2. Secure the grinder to a pillow, cushion, chair or a partner's thigh using the included straps. Make sure it is firmly positioned and won't shift during use.
3. Apply water-based lubricant to the textured surface and to yourself. This reduces friction and lets the texture glide rather than drag.
4. Straddle the grinder and lower yourself into a comfortable position. Take a moment to work out where you actually want the tentacle sitting.
5. If you're using the bullet, start it on a low speed and adjust from there.
6. Begin to move slowly. Grind, rock, roll or bounce to find the angle and pressure that works for you.
7. Adjust as you go. Small changes in position make a surprising difference on a shape like this.
8. When finished, remove the bullet if you used one. Clean the grinder with warm soapy water or a suitable toy cleaner, then allow it to dry fully before storing.
▶ Tips For Getting The Most From It
- Give the first session a bit of patience, most people need a go or two to find their spot on a textured grinder
- Slow down. The shape and the finer texture both need a moment to register, rushing turns them into one blur
- Rock your hips to move your body up and down the tentacle rather than staying in one spot
- Use your body weight to control how hard the texture presses back
- Mount it on something with a bit of resistance, a firm cushion beats a duvet
- If you have the bullet, try it both on and off, they're genuinely different experiences
- Top up the lube before it starts dragging rather than after
▶ Why We Made This Toy
A flat pad or a raised mound will get you there, and there's a reason so many grinders are built that way. They're simple, they're intuitive and they work. We wanted to find out what happened if the shape itself did more of the work.
So the tentacle became the toy. It arcs over the coffin, thick through the middle and tapering away, and you rock along the length of it. The pressure changes as you go because the shape changes, and the tendrils and ridges between the suckers add a finer texture over the top of that. It's something to grind against rather than something to grind on.
The Coffin Grinder came from Odyssey, our darker sister brand, where it was built around a tentacle claiming a coffin at the tide line. We're bringing it over for spooky season because it's a genuinely stunning object. It's practically a diorama, right down to the wet stone and scattered debris around the base, and every bit of that sculpting still earns its place as something you get off on.
Adding the bullet cavity underneath the texture was the other half of it. Vibration and texture usually compete for the same bit of surface. Here the bullet sits below the tentacle and pushes up through it, so you get both at once instead of choosing.
▶ Materials & Safety
Materials
- Made from 100% high-grade platinum-cured silicone
- Coloured using body-safe, non-toxic pigments
- Free from phthalates, latex, BPA and plasticisers
- Non-porous, hypoallergenic and designed for long-term use
Platinum-cured silicone is considered the gold standard for body-safe sex toys due to its durability, flexibility and resistance to bacteria.
Body Safety
- Fully non-porous — will not harbour bacteria when cleaned properly
- Safe for external use
- Compatible with water-based lubricants only
⚠ Do not use with silicone-based lubricants, as they may damage the surface.
Allergies & Sensitivities
- Suitable for most people with sensitive skin
- If you have known sensitivities, we recommend performing a patch test before extended use
Cleaning & Care
- Remove the bullet vibrator before cleaning
- Wash before and after each use with warm water and mild, unscented soap or a dedicated toy cleaner
- Pay attention to the tendrils and the gaps around the suckers, where lubricant likes to collect
- Allow to air-dry completely before storing
- For deeper cleaning, toys without electronics may be boiled for 3–5 minutes (if size and design allow)
Storage
- Store in a clean, dry place away from direct sunlight
- Keep separate from other silicone toys to prevent surface interaction
- Use a fabric pouch or original packaging where possible
▶ FAQ
Does it vibrate?
Not on its own. As standard it's a plain grinder and everything comes from movement, pressure and rhythm. Add the bullet upgrade and it does.
What do I get with the bullet upgrade?
We build a cavity into the base while we're casting it, and a 7-speed bullet vibrator comes with it. The bullet sits just underneath the tentacle texture, so the vibration comes up through the surface you're grinding on.
Can I take the bullet out?
Yes. It comes out for cleaning, or to use on its own.
Can I add the cavity later?
No, sorry. It's formed during casting, so it has to be decided when you order.
Is anything insertable?
No. This one is purely external, it's all about what you grind against.
Does it actually stay put?
Yes. The straps secure it to a pillow, cushion, chair or a partner's thigh so it isn't wandering off mid-grind.
Is it beginner-friendly?
Very. Strap-down grinders are about as intuitive as toys get, you're in charge of everything. Expect to spend your first session working out where you want it, that's normal on a shaped grinder.
Which firmness should I pick?
Extra Soft or Soft for most people. Medium is very firm and only worth it if you already know you like really firm clitoral stimulation.
Will mine look exactly like the photos?
Close, but not identical. Every one is poured by hand, so colour placement shifts a little from toy to toy. That's the point of handmade, it never affects safety or how it works.
How do I clean it?
Take the bullet out first, then warm water and mild soap or a toy cleaner. Work into the texture where lube likes to hide, then let it dry fully before you put it away.
