Can you recommend a really large indoor play yard or gate product for a crawling baby? - safety first baby gate

Our baby started to crawl when we) in a playground in the house (room, so you may not want to put continued. Something like that, http://store.babycenter.com/product/safety+-+baby+care/safety/gates/superyard+xt.do?asc=false, but much larger (and thus move a lot of space to read and study) and is expected to be fine. I prefer something a grid instead of bars. In addition, some are free standing, as the above, nothing that requires the construction or drilling holes in the wall, please. Can anyone recommend a product? The brand and model name and number is high, a link would be even better. Thank you!
