We first stumbled across Howard Street's foam superstore online, and slowly have discovered what a great resource it is. More than just a soft, hypo-allergenic substance upon which to rest your weary head, foam is good for insulation, sound-proofing, mattress topping, and costume-making. When looking to re-make some old foam cushions for a rocking chair we bought on eBay, we discovered we could input measurements and grade preferences into FoamOrder.com's website, then drop off the fabric in person. FoamOrder.com then creates custom slip covers, using our fabric or their own limited selection.
The wide variety of foam shapes
FormOrder.com are foam experts. They sell all varieties of foam, from memory foam products to Tempur-Pedic mattresses, natural latex crib mattresses to costume-making and DIY upholstery supplies. They also have custom-made down products and industrial foam products (like acoustic foam), as well as a variety of foam-fitted furniture.
Portable Tri-fold Futon
The website isn't flashy, but it bursts at the seams with well-organized information about foam. You can also visit the store in person.
