Good for splashy older kids, but the soft play and upkeep sound seriously underwhelming.
The long read worth saving for nap time
What’s it actually like?
The Triangle is a Sussex leisure centre offering swimming, a soft play area, and hall or racket sports hire. From the reviews, the main draw is the pool and its features, rather than any one standout family attraction. Families with older children seem to get the most out of it: there’s a fast slide, rapids, a waterfall and general swim fun, plus friendly staff and the option to book online without faff. One reviewer happily stayed for four hours, which suggests there’s enough to keep active kids occupied. The downside is hard to ignore. The soft play sounds tiny, cramped and poorly suited to under-twos, while several reviewers complain about broken features, closures and poor maintenance in the pool area. Parking is also an issue, and the value for money looks patchy unless everything is actually working.

THINGS PARENTS ASK
Common questions
Is the soft play good for toddlers?
Not really. Reviews say it is very small, cramped, and has very little for under-2s.
What’s the best age group here?
School-age children, especially around 5-11, seem to get the most out of the pool and slides.
Does the pool have fun features?
Yes, but several reviews say rapids, waterfall, mist spray and hot tub features have been out of order.
Is it good value?
Only if the full pool experience is working. Several reviewers felt the price was steep for what they got.
