Cage Accessories That Matter: Pads, Covers, Locks, and Anchors
By Remy Vale · Tested and researched by the Home in Bold team · Updated September 2026 · 8 min read
Key Takeaways
- Four accessory categories do the real work on any cage: base padding, a cover, a proper lock, and floor anchoring. Everything else is decoration.
- Bare steel bars end sessions early: a padded base is the difference between 20 minutes of comfort and an hour or more.
- The lock rule is non-negotiable: a key or code stays within reach of a second person the entire time someone is locked in.
- A rolling cage needs locking casters engaged before use; an unplanned 2 in roll mid-scene is startling at best.
- Budget roughly $50 to $150 for aftermarket pads and covers combined, or buy a cage that includes them and skip the retrofit.
The cage this guide keeps referencing, because it ships with the padding, lock, and casters most cages make you buy separately.

A BDSM cage needs exactly four things beyond its own frame: padding between the occupant and the steel, a cover for enclosure and privacy, a lock that works as agreed, and anchoring that keeps the cage planted. That is the whole list. The accessory market will happily sell you more, but comfort, control, and stability are what decide whether a cage gets used monthly or becomes the world's most awkward coat rack.
The reason this short list matters: cage sessions live or die on duration. Almost anyone can sit in a bare cage for ten minutes. The people who love cage play talk about long, settled stretches, reading, waiting, being kept. Steel bars against a hip bone put a hard cap on that. So does wondering if the door lock will pop open, or feeling the cage shift on the floor.
This guide covers what each category does, what to spend, and what to skip. For the frame itself, sizing, and safety fundamentals, start with our complete BDSM cage guide and come back here for the fit-out.
Pads and Base Comfort: What Goes Under the Occupant
Start at the bottom, because the base takes almost all of the occupant's weight. A kneeling or seated adult concentrates load on knees, shins, and sit bones, and bare bars turn that into pressure points within minutes. You want a padded platform, not loose cushions. Cushions migrate. A fixed platform with upholstery stays put when the occupant shifts.
If you are retrofitting, look for high-density foam at least 1 in thick with a wipeable or machine-washable cover cut to the base dimensions. Memory foam feels plush for the first minutes, then bottoms out; firm upholstery foam holds shape for a full session. The full argument for upholstered platforms over bare steel is in our piece on cage padding.
One workshop note. During padding tests I knelt on a bare steel base for a timed comparison. Eleven minutes. That was my honest limit before my kneecaps filed a formal complaint. On a firm upholstered platform I stopped the timer at an hour because I got bored, not sore. Padding is not a luxury add-on. It is the difference between a prop and furniture.
A fixed padded platform beats loose cushions: it cannot migrate when the occupant shifts.
Do Cage Covers Earn Their Keep?
Yes, and for two different jobs. Job one is psychological: draping a cover over an open-bar cage changes the experience from being in a room to being kept somewhere. Sensory reduction deepens the headspace for a lot of occupants, the same way a blindfold does. Job two is mundane: a covered cage in the corner reads as furniture under a throw, which matters in shared homes.
Fabric choice is where covers go wrong. You need airflow. A heavy blackout fabric across all four sides turns a cage into a slow cooker, so use breathable cotton or a poly-cotton blend and leave the door face uncovered or loosely draped. Check on the occupant more often once a cover is on, since you lose the visual.
Skip purpose-made covers priced like furniture. A queen flat sheet costs about $15, washes at 40 C, and covers a 30 kg cage completely. Save the budget for padding and locks, which cannot be improvised safely. The one upgrade worth paying for is a fitted cover with a zip door panel, if you find one cut to your cage's actual dimensions.
Locks: What Holds, What Just Looks Good
A cage lock has one safety rule that outranks every product recommendation: someone other than the occupant can open it, immediately, the entire time it is engaged. Key on a lanyard around the keyholder's neck, spare taped inside a cabinet both partners know about, or a combination both partners have memorized. If the answer to where is the key involves the word somewhere, the lock stays open.
On hardware: a lock only performs as well as what it is attached to. A hasp on thin decorative bars is theater. Look for a latch and lock point welded or bolted to structural steel, which is why the CELLMATE uses a lockable steel door on a reinforced frame rather than a padlock looped through bar gaps. For a deeper comparison of latch styles and what to check before buying, our cage lock buying guide goes bolt by bolt.
Keep a pair of bolt cutters or a backup key in the same room for a locked scene. Not because the lock will fail. Because a fire alarm does not wait for you to remember a combination under adrenaline.
A lock point on structural steel: the latch is only as strong as the bar it closes against.
Anchors and Casters: Keeping the Cage Planted
Stability is the accessory category everyone forgets until the cage moves. A cage shifts for two reasons: it is light relative to its occupant, or it is on wheels. The CELLMATE frame weighs 30 kg (66 lb), and an occupant leaning into the bars can still walk a rolling cage across hardwood if the casters spin free. The fix costs nothing: engage the caster locks before every session, all of them, not just the two you can reach. Our short guide on locking cage casters covers the details.
Here is the honest comparison of what each accessory category costs and does.
| Accessory | Typical aftermarket cost | What it changes | Included on the CELLMATE? |
|---|---|---|---|
| Base padding | $40 to $80 | Session length, from minutes to an hour plus | Yes, velvet platform |
| Cover | $15 sheet to $60 fitted | Headspace, privacy, daytime disguise | No, use a breathable sheet |
| Lock | $10 to $40 | Consensual control, only as strong as its mount | Yes, lockable steel door |
| Anchoring | $0 to $30 | Stability on hard floors, no mid-scene drift | Yes, locking casters |
| Accessory storage | $60 to $120 | Keys, cuffs, and covers in one coded place | No, see the VICE VAULT |
On carpet, engaged caster locks are enough. On hardwood or tile, add a rug or rubber mat under the footprint. It protects the floor, quiets the frame, and adds friction all at once.
How Do You Store the Small Stuff?
Badly, usually. Cage accessories are exactly the wrong shape for a nightstand drawer: a spare key that must be findable in seconds, cuffs, a folded cover, cleaning spray. Scattering them across the bedroom means starting every scene with a scavenger hunt and ending it with evidence on the dresser.
Give the kit one home. The VICE VAULT is the one we designed for the job: 18.5 x 9.53 x 7.2 in, wooden with a 3-digit code lock, big enough for restraints, cover, and spares in one place. The code lock does double duty, keeping the kit away from guests while staying openable by either partner without hunting for a key. One caveat that matters: the emergency spare key for a locked cage lives OUTSIDE the coded box, somewhere the non-keyholder can reach it in seconds. The box keeps things private, not inaccessible.
Wipe steel bars monthly and after sweaty sessions, wash fabric parts on the schedule in our cage care guide, and the whole setup outlasts the relationship that bought it. Kidding. Mostly.
One coded home for cuffs, covers, and spares. The cage's emergency key lives elsewhere, within reach.
66 lb
CELLMATE frame weight (30 kg). Heavy enough to feel planted, light enough that locking casters, not brute force, do the anchoring.
Pre-Scene Cage Check
- ✓All caster locks engaged, cage does not shift when pushed
- ✓Base padding in place and dry
- ✓Spare key or memorized code confirmed by the non-locked partner
- ✓Cover fabric breathable, door face loosely draped at most
- ✓Phone and cutting tool in the same room for a locked scene
⚠️ Never leave a locked, caged partner alone in the home, and never engage a lock without a second person able to open it immediately. Enclosure play is psychological; the safety margin has to be physical.

View CELLMATE BDSM CageFrequently Asked Questions
How much should I budget for cage accessories?
Plan on $50 to $150 total if your cage shipped bare: padding is the big line item at $40 to $80, a breathable cover runs $15 to $60, and a decent lock is $10 to $40. A cage that includes padding, lock, and casters cuts that near zero.
What padding thickness works for a cage base?
At least 1 in of high-density upholstery foam under a wipeable cover. Thinner foam bottoms out under kneeling weight within about 15 minutes, and memory foam compresses too fully to protect knees and sit bones for long sessions.
Can I use any padlock on a cage door?
Only if the latch point is structural. A padlock through decorative bar gaps can bend its mounting under one hard pull. Look for a latch welded or bolted to the frame, and always keep 1 backup way in, a spare key or bolt cutters, in the same room.
Do I need to anchor a cage to the floor?
Almost never. A 30 kg (66 lb) steel frame with all caster locks engaged stays planted for normal use on carpet. On hardwood or tile, add a rubber mat under the footprint for friction; drilling into floors is overkill for home cages.
Is a fully covered cage safe?
Cover 3 sides at most with breathable cotton and keep the door face open or loosely draped. Full blackout fabric on all 4 sides traps heat fast, so check in more frequently once any cover goes on and skip covers entirely in warm rooms.
