NIB. This thing is a parent’s best friend when it comes to carrying a heavy car seat. LugBug is a comfortable attachment for any baby car seat carrier that eases tension on the wrist, forearm, and shoulder. The handle adjusts to any baby carrier and offers a range of better, more comfortable and enjoyable carrying positions that support your arm and wrist. It increases grip stability and decreases lifting effort with a handle that swivels 360 degrees. It is proudly designed in the USA, by a dad.
