Wayfair's delivery of this large item was excellent. The delivery truck drivers were helpful and courteous and moved this very heavy box into the carport so it would out of the weather and accessible for me to unpack.  The material looks sturdy. I haven't put it together yet though as where I wanted to place it -- on a mulched landscape area won't be suitable. Once I read the instruction it indicated it would be best to put wooden boards/planks under the plastic floor.  But, that one detail stopped me in my tracks and I have yet to assemble it.  Notice in the picture the nice level solid surface under the shed.  That's what is best for it. So plan your placement of the shed with that in mind.  I will keep the shed and hopefully come next spring find a place to put it. But, Wayfair I give high marks for their free and excellent delivery experience.
