"A feature-rich recliner for average builds, masquerading as a durable 'big and tall' chair."
The 'Pocket Spring Cushion' is a low-cost method to create initial plushness, but unlike solid high-density foam, these small springs will likely fatigue and lose supportiveness much faster.
This chair is for an average-sized person, under 6' and 220 lbs, who wants maximum recline and a footrest for the lowest possible price. They should be prepared to replace it within three years.
Anyone genuinely tall or heavy should ignore the 'big and tall' marketing and the 300 lb rating. Buyers seeking long-term durability or breathable materials will be better served by simpler chairs with better construction.
