How I wish they made flat seats also for smaller people. Only the biggest model typically comes without the sides at the base but it's typically a bit on the larger side for me as I'm pretty slim. Here's hoping it's a trend that catches on that people with basic logical thinking ability see the sides are more harm than useful for a office chair so they create smaller ones without the leg support which makes no sense in seat not intended to be used in a car.
I’ve been using a Staples Kroy Mesh chair for work and just bought me one for home use. Super comfortable as I have lower back problems when sitting for extended period of times. The mesh seat helps against the pressure and allows me to be comfortable.
I ended up getting a Tempur-pedic chair from Staples. Model TP7000, this replaces the gaming chair that I was hoping would get more comfortable, but never did. The best thing is I went to my local Staples and the chair was marked down to $168 from $300..
