Sales at IKEA Ireland rose by 7.4% in the past year to reach €181.5m.
The company said that 9.5% of sales were made online, a service the company launched less than a year ago.
It noted that Dublin-based online shoppers were the biggest group for volume of online orders, followed by Cork, Galway and Kildare.
IKEA said it now holds an 8.7% market share in the Irish home furnishing market.
As a result of the summer heat wave, IKEA's outdoor furniture was the its biggest area of growth last year, with a total sales increase of 29%.
It said its best-selling product online based on sales was the Hemnes day bed and the most popular products in store were the white Kallax shelving unit and the white Ribba frame.
Claudia Marshall, IKEA Ireland's Market Manager, said the company was delighted to complete another successful year of growth in Ireland and see the business grow from strength to strength.
"Our investment in multi-channel retailing this year was in direct response to the changing needs of our customers, and Shop Online was a big part of this journey," Ms Marshall said.
"It has been a great success and has performed strongly in its first 10 months in operation, giving customers all over Ireland the opportunity to shop with IKEA whenever and wherever they want. We look forward to seeing this growth continue into 2019 and beyond," she added.
Ikea operates its flagship store in Dublin's Ballymun, while it also has a smaller outlet in Carrickmines in south Dublin.
