Amazon calculates a product's star ratings using a machine learned model instead of a raw data average. The machine learned model takes into account factors including: the age of a review, helpfulness votes by customers and whether the reviews are from verified purchases.
Update- the missing piece was shipped within 2 days. Thank you for the quick turnaround.
Would have rated 5 stars. Reason for the 3 stars is below. Product seems great. Just got it delivered. The only problem is one of the chairs is missing a leg. Luckily it’s just my daughter that will be using this. She doesn’t have a sibling but I can imagine it would not have been a good experience if the second chair was intended on being used right away. Disappointing and hoping to have the piece sent ASAP or will be asking for a refund. Otherwise seems like a good product.
