(AP) — Toys R Us will go before Massachusetts’ highest court Monday to appeal a $20 million jury award to the family of a Colorado woman who died after an inflatable in-ground pool slide partially collapsed.

Robin Aleo was attending a pool party in Andover in 2006 when she slid head first down a “Banzai” slide sold by Wayne, N.J.-based Toys R Us. The slide partially collapsed and she slammed her head on the concrete pool deck. Aleo died the next day.

In 2011, Toys R Us was ordered to pay Aleo’s family $20.6 million.

During trial, lawyers for Aleo’s family said the slide didn’t comply with federal safety standards.

Toys R Us’ attorneys say the Consumer Product Safety Commission regulation cited by Aleo’s family only applies to rigid slides, not inflatable ones
