Overview
['The S05 is built with a removable cushion made from memory foam, short plush, and sponge layered together, aimed at dogs under 35 pounds. It ships with 2 safety leashes rather than the single belt found on many competing seats, plus storage pockets for treats or supplies.', 'The whole unit is detachable and can be machine washed or hand washed, and it measures 17.8 inches long by 17.8 inches wide by 18.9 inches tall. It is also backed by a 2 year warranty, longer than most other seats in this lineup.', 'At $59.48, it is priced at the higher end of this group, but the payoff shows up in the reviews: a 4.7 star average across roughly 1,100 to 1,178 reviews, with about 100 units bought in the past month.']

Performance notes
The layered memory foam, short plush, and sponge cushion is removable for washing, and the two included safety leashes give a more redundant setup than seats that rely on a single belt. Its 17.8 by 17.8 by 18.9 inch dimensions make it best suited to dogs up to 35 pounds.
