I'm 68 year old woman,I thought my grandson would have to assemble this, I pulled it out of the box,the top part,the Backrest slides into 2 prongs on the bottom and it's assembled!  Very impressed as other items I have ordered that Saif easy assembly were a nightmare, this was so easy! Side tab pops out the legrest,very easy to use! Let's hope it holds up well,I'm a fan!
