Conclusion
The cheaper Aodisman three-step model suits a low couch when its dimensions and conservative weight guidance fit your dog. Choose the taller ZOMISIA five-step model when your furniture needs more height and you have room for its longer base.
3 selected products
Buying dog stairs by step count alone can leave the top step well below your mattress or the base in your walking path. Before choosing a color or chasing the lowest price, check these three things, in order.

Will the stairs fit your furniture and floor space?
Measure the furniture surface and the available floor space before comparing step counts. EHEYCIGA lists its gray four-step stairs at 18 inches high, while ZOMISIA lists its gray five-step version at 22.8 inches high. Aodisman confirms a 15.7-inch height for its gray three-step model on its official product page.
Measure from the floor to the top of the couch cushion or mattress where your dog will arrive. A bed frame measurement leaves out the mattress, and a thick comforter can obscure the edge. Compare that measurement with the actual stair height, then look at the remaining transition onto the furniture.

| If your home has... | Our take | What to check |
|---|---|---|
| A low couch and room for a short base | Worth it | Aodisman three-step height and the transition onto the cushion |
| A medium-height bed beside an open aisle | Worth it | EHEYCIGA four-step height and base dimensions |
| A taller bed with generous space beside it | Only some models | ZOMISIA five-step height and longer base |
| A narrow passage where the base blocks daily access | Skip it | Another placement before ordering |
| Furniture well above the highest step | It depends | Whether a taller model would fit better |
EHEYCIGA's base measures 24 inches deep by 15 inches wide. ZOMISIA needs 33 inches of depth and 15.7 inches of width. Mark the footprint with painter's tape, then open nearby drawers and walk your usual route from the bed to the door. Keep the approach space in mind, too; the product footprint does not include it. EHEYCIGA specifications, ZOMISIA specifications.
Aodisman has a listing inconsistency worth resolving before a tight-space purchase. Its Amazon dimension field says 22.4 inches deep by 15.7 inches wide by 15.7 inches high, but another field says 22.05 by 15.55 by 15.35 inches. Its official page confirms the nominal height and width, without listing depth. Leave room rather than planning a fit that depends on an exact edge measurement. Aodisman specifications.
EHEYCIGA advertises its four-step version for beds up to 23 inches, and ZOMISIA's title mentions beds up to 25 inches. Those furniture claims do not change the actual top-step heights. Choose around the transition your dog will need to make, rather than treating an advertised furniture range as a flush fit.
Can your dog manage the steps and their surface?
Stairs make sense when your dog can manage steps; a weight rating alone does not establish that fit. The American Kennel Club's guidance recommends pet stairs for senior dogs that still have good balance and agility, and suggests a ramp when stairs are no longer manageable. It also calls for deep treads, a surface with grip, and a rating suitable for the dog's weight. American Kennel Club guidance.
Aodisman describes a corduroy cover and a non-slip base. EHEYCIGA lists foam with a support board, while ZOMISIA describes plush fabric and a non-slip bottom. These are construction details to compare with your room's flooring; the makers' descriptions do not establish how much movement will occur on your particular floor.
The American Kennel Club's weight guidance makes the published limits worth checking carefully. EHEYCIGA specifies up to 35 pounds. ZOMISIA advertises up to 60 pounds. Aodisman recommends pets under 50 pounds on its official page, although its Amazon detail table lists 60 pounds. Use Aodisman's more conservative recommendation when narrowing the choices. EHEYCIGA listing, ZOMISIA listing, Aodisman maker guidance.
Individual tread depth and rise are not listed by the maker for these exact versions in their published specifications. Overall height divided by step count is not a substitute, especially with curved foam steps. If your purchase depends on a particular tread size, ask the brand for that measurement before ordering.
- Compare your dog's weight with the maker's recommendation for the exact version.
- Request tread dimensions if your dog needs a specific step shape.
- Follow PetSafe's acclimation guidance: let the dog approach voluntarily and reward interest with treats and praise.
PetSafe's instructions are for its own pet steps, but offer a useful introduction method; the company says timid pets may need time to become comfortable. PetSafe setup guidance.
What will setup and cleaning involve?
Check whether you can remove and clean the cover, and allow for foam expansion before planning daily use. EHEYCIGA says its cover can be hand washed or machine washed and its inner foam cannot be washed. ZOMISIA gives the same cover options and says not to wash the foam with water. EHEYCIGA care instructions, ZOMISIA care instructions.

Aodisman says the outer cover can be removed and cleaned, but machine-wash settings and drying instructions are not listed by the maker on its official product page. Check the care label before treating it like the other covers. A removable cover is useful for routine dirt, but it does not tell you how to handle liquid that reaches the core.
The makers also specify different expansion times. EHEYCIGA says to allow 24–48 hours after unpacking. ZOMISIA gives 24–72 hours. Aodisman's Amazon instructions say 48–72 hours, while its official page says 24–48 hours. For Aodisman, budget for the longer published window and follow the instructions packaged with the exact model.
- Find the cover zipper and check the wash and drying directions.
- Plan where the unpacked foam can expand without occupying a busy passage.
- Ask about a replacement cover if you want a spare for laundry days.
ZOMISIA's zipper connects separate sections that can form the full five-step stairs or separate three-step and two-step pieces. That flexibility may suit furniture in different rooms, but you still need to measure each intended placement. EHEYCIGA also says its stairs can fold into a pet bed. These features matter most if you will actually change the setup; for a permanent bedside location, height and cleaning access are more useful priorities.
How do the popular picks compare side by side?
Aodisman suits a low couch, EHEYCIGA offers a middle-height option, and ZOMISIA adds height when the room can accommodate its longer base. The models below differ in actual dimensions and maker guidance, so match the exact version to your home.

The lower-priced Aodisman is enough when its height fits your couch and its specifications meet your needs. Paying for ZOMISIA makes sense when you need the taller top step and have space for the longer base. EHEYCIGA falls between them in height, with explicit cover-washing instructions.

Frequently asked questions
How tall should dog stairs be for my bed?
Measure from the floor to the mattress surface, then compare that height with the actual highest step. EHEYCIGA lists an 18-inch stair height and ZOMISIA lists 22.8 inches; their advertised furniture ranges are different from those measurements. Check the remaining transition onto the mattress before ordering.
Are dog stairs or a ramp better for an older dog?
The American Kennel Club recommends stairs for senior dogs that retain good balance and agility, and suggests a ramp when stairs are no longer manageable. Its guidance also calls for suitable weight support and a surface with grip. Age alone does not select the right design.
Can I wash foam dog stairs in the washing machine?
EHEYCIGA and ZOMISIA allow hand washing or machine washing of the removable cover, while instructing owners not to wash the foam core. Aodisman says its cover can be removed and cleaned, but wash settings are not listed by the maker on its official page. Follow the care label for the exact version.
