Misty 50cm H Upholstered Side Chair

Like the chairs and well upholstered. However 3 of the chairs wobble badly on the floor. Not the floor as l have moved the chairs around. Not good when l spent over £1000 on 4 chairs! Also had problems with an iron archway l bought for the garden. Was asked to send photos which l did. No response. So not happy with wayfair. First time l have bought from you and not a good experience.
