I know my kids would enjoy a play tent in the house. The major thing that holds me back from buying one and similar large items is the storage issue.
Carolina Gomez must have had similar concerns when she came up with La Tente, a beautifully designed folding play tent. La Tente sets up easily and folds down to only 4 cm thick so you can store it in a closet or other small space with ease. For purchasing information and more photos of La Tente, check out Mouta.
