The RRP at nearly £420 would be a complete rip-off! Fortunately, I bought it at sale price, and just as well!  In the description, it says, 'Seat reclines up to 130°!' This is impossible because the armrests are screwed firmly to the base and the back, which in my retired engineering mind tells me that something is wrong. Also not putting too fine a point on it, this is also in contravention of the Trades Description Act 1968, which clearly states that it is an offense for businesses or salespeople to sell a product or service based on misinformation.'
As for massage, well this is pretty poor! I have personally sat in massage chairs that really massage, this just tickles! Hence it is being used as a gimmick to help sell the product! I have two suggestions, (1) get that description about reclining removed, and (2) tell the supplier to rewrite their instructions for assembly. On a more positive note, it is quite comfortable, and I like the material.
