Review: Provides needed leg support - Some cars come with leg extenders built in seat, mine didn't. Adding this provided needed support I missed, especially during longer drives. It's comfortable, has air cushion to enhance support to needed level and installation was quite easy. Only enhancement I would recommend to the product is that the air pump is in right hand side. Since I bought two, one for driver side, the other for passenger side, the pump on passenger side hangs towards the door. If there was an option to select left or right sided pump it would be ideal. Otherwise couldn't be happier with this purchase. Been using it for a week or so and so far it is working as designed. Looks to be matching with my car seats and though material differences, doesnt look odd after install. Build quality is really sound. It definitely helped with comforting my legs with extended and adjustable support area.
Review: Good support but needs clips instead of hooks - The bottom hooks keep coming off. I had to take wire to make them stay on.

### ⭐⭐⭐⭐ Good support but needs clips instead of hooks
*by M***K on July 6, 2025*

The bottom hooks keep coming off. I had to take wire to make them stay on.

### ⭐ Did not work
*by V***M on November 21, 2024*

This is not comfortable. It too bulky and my knees hurts. Also not stable. I am 6 ft and this did not work for my Honda CRV 2024 EX.
