Event Summary

Join us on Friday, June 9 for Mattress Factory’s signature themed fundraiser and the hottest costume party in Pittsburgh, bringing together a colorful 21+ crowd that sets this event apart.

Cast aside? Not at the TRASH BASH GARDEN PARTY!

Calling all Magicians of Mischief, Captains of Creativity, and Icons of Ingenuity: You’re invited to transform into Darlings of Detritus and Rulers of Refuse. Repurpose, recycle, and reuse all that has been forgotten to make an unforgettable statement at THE party of the summer.

Anything goes on this evening of metamorphosis featuring food and drink from some of Pittsburgh’s best restaurants and bars. Enjoy a night of art installations, an art auction, musical performances and dancing. Join us as we shift our perspectives and push trash far beyond its definition, courtesy of Event Architect Thommy Conroy.

At the Main Stage, groove to the sounds of Tony From Bowling, The Cookie Table, and Everything The Light Touches. Get down and flirty with Steel City Kitty, and hear The Beagle Brothers bring our Winifred Lutz Garden to life with their country twang.

Doors open at 5:30 PM for VIP and Friend of the Mattress Factory ticket holders, and 7 PM for General Admission.

What should you wear?

This is a themed costume fundraiser after all!
Grab your discarded items and unconventional materials – give it worth and make it work. From the junk drawer to the recycling bin and beyond, transform your found materials into fashion. If you’ve got it, flaunt it – and by ‘it’ we mean your trash.

Also, get hyped for the TRASH FASHION CONTEST, hosted by Pissy Mattress, who will be on the lookout for guests in the finest garbage-turned-garments. Lucky guests will be selected and invited to parade on stage, with audience applause determining who advances to each round. The best trash transformation will be crowned the Garden Party Golden Guest – and have a chance to defend their title next year.
