The Kelburn and the Copper feature nearly identical constructions, however, one of the most noticeable differences between the two beds is their price. While a Queen size Kelburn comes in at $1,300, a Copper Queen goes for a cool $1,600. Each bed also features a section that’s unique to them, as seen in either the Extra Soft Foam in the Kelburn or the Sealy Support Foam in the Copper.
