I wasn't expecting much from this inexpensive mattress. it was to replace an old futon mattress.it was delivered in a duffle bag. i found the mattress compressed and shrink wrapped. the mattress springs decompressed when i opened the heavy plastic shrink bag. the mattress expanded to it's full normal size in less than a minute. i was pleasantly surprised with quality. it was a big improvement in looks and comfort from the original futon mattress. the "new" smell dissipated in about 2 days.
