World Snooker will "monitor conditions closely" after criticism of the tables at the World Championship in Sheffield.
On Saturday, table one at the Crucible Theatre was described as "the worst I have ever played on" by Ali Carter.
Organisers say they have already taken steps to try and improve conditions at snooker's most prestigious event.
"We changed the cloth and cushions on Wednesday, and we will change the cushions again on Saturday," World Snooker said in a statement.
Saturday night's planned cushion change was "scheduled before the event", it added.
The governing body also said it has allocated a set of balls to every match, rather than one set for each table, and turned the table heaters down "in order to make the cushions more consistent".
"We believe these measures, together with Saturday's cushion change, will have a positive effect," added World Snooker.
On Friday, Welshman Mark Williams wiped the cushions down with a damp cloth in order to stop the number of uneven bounces from the cue ball.
Two-time finalist Carter, who suffered several kicks and heavy bounces off the cushions, was irate after losing 13-11 to Alan McManus in the second round.
"The conditions were horrific. There were kicks every other shot and big bounces off the cushions," said Carter. "I just wanted to smash the place up at the interval, I was that frustrated."
Michael Holt, who suffered a 13-8 defeat against two-time champion Williams, also expressed unhappiness.
"I am not going to criticise the tables but I can observe them," added Holt. "They were... interesting.
"It was about being the best guesser. You just need to watch it and see what was happening, we are not that bad."
The two-table situation remains until the semi-final stage, when it switches to one.

大致内容：球员普遍对球台提出了质疑和批评。
机长说这是“我打过的最差的台子”。
主办方说我们已经在想办法了。前几天换了一次台布和库边了，过两天还得换。过几天换的是原来就计划好的。
每次比赛都换一次球，以前是一张台子一副球打到底。还把加热器关了保证库性更好。
周五威廉姆斯还拿布擦库边，防止球碰库边有加速或者减速效果。
卡特和霍尔特都对台子不满意，霍尔特的话是“they were...interesting”。
