i cant vouch for the glider chairs, but i can for getting it seccond hand!!
i was looking for one when i was pg with dd, i ended up getting a massage chair online for $50 brand new (new age shop was relocating and they not long got it for the boss but couldnt take it shame for them, yay for me!) it is in the same style as the leather gliders, only it dosent glide. it reclines and has 9 diffrent massage settings and a matching foot stool, it was bliss on my lower back late in pg and after i had her, i had it in her room and quiet often fell asleep in it feeding her in the early mornings!! you cant even feel the massage nodule things when you sit on it unless its on. at the moment df has claimed it for his "lounge chair" but im going to be taking it back verry soon! if i had gotten a glider like first planed i probably would have goten rid of it months ago.
hoope you find the chair thats right for you.
