As always, I am impressed by the speed at which items are delivered.   I am a single woman aged 56.  I feel I am fairly handy but the assembly instructions were horrible.  It took me almost 3 hours to assemble.  All parts were present and accounted for and everything lined up well, it was just difficult to read.  There were diagrams only, nothing in writing.  You had to study the pics to figure out which bolts went where.  Various size bolts were all mixed in together and had to be sorted carefully because they all looked alike and were very close in length.  It sits very comfortably and does glide fairly well but not as much as I thought it would.  Overall, for the price, I would give it 4 stars.
