Lee Valley Tools has them in their hardware catalog.

What hinge or hold open is it exactly? We just built a window seat and my husband is about to add the lids on top very similar to what you have done here and we weren't sure what to put on the lid to make it safe for our two little ones and keep them from smashing their fingers. Thank you!

Go to www.leevalley.com or call 1-800-267-8767 for their beautiful hardware catalog. There are a number of lid supports that let a bench or toy box lid down slowly, on page 137. This is a Canadian company that sources top quality tools and cabinet hardware world wide. They will mail you the tools or hardware catalogs, or both, free.

I love these window seats, I had them in my old house and was a great storage for big bulky items. We're redoing a room that is. Ow basically

I LOVE Lee Valley! it's in Ottawa (a store front that is) their catalogues are amazing and service unmatched!
