Based on published listings, not hands-on testing.
Why consider it
KSIIA's removable-cover egg-crate mattress is worth comparing with its washable plush pad. We'd choose based on whether washing a cover separately is more useful in the household.
What could make us pass
The two KSIIA listings have different descriptions of the core and care setup. They should not share a price comparison merely because both are 35 inches.
Fit and care
Measure the complete resting surface and any crate or carrier floor it must fit. Check the thickness and whether the care instructions apply to the cover, the core or the complete pad. Avoid a size that bunches inside the intended space.
Size evidence still needed
This model remains available for research. We do not substitute outside or nominal dimensions for usable inside space, so it is not in measured-size recommendations.
