Hi!
My biggest regret is not going with 6' or 7' depth in the middle and having one end 3 1/2 instead of going with 4 ' on each side. My grandkids spend about 90% of their time jumping in and climbing out to jump back in, over and over. At 5 1/2', my 6 yr old grandson is already touching the middle bottom when he jumps, so now we are having all the kids tuck when they jump so no one gets hurt.
Thanks! I will definitely consider that! I have a 5 year old and lots of little cousins, so I definitely want it to be usable and safe for them to have fun.
