Homewares retailer Dunelm's first quarter revenues fell by 1.8% to £198.7m.
Total like-for-like growth (combining LFL stores and home delivery) decreased by 3.8%.
Unusually warm weather in the 13 weeks to 1 October had a dampening effect on store footfall.
But the group said it continued to see good growth in the online business, including a 17.9% increase in home delivery sales. Overall, Dunelm believes it is continuing to outperform the homewares market as a whole.
Chief executive John Browett said: "As expected, the homewares market has fallen due to unusually warm weather and this has correspondingly impacted our store performance over the period given the reduced footfall to our out-of-town superstores. However, we have continued to focus on our value based customer proposition and are increasing our market share in homewares, whilst also seeing good growth in our online business.
"We are looking forward to a stronger second quarter as we continue to invest in extra seasonal space, new till systems, store refits and new store openings. We should also benefit from weaker comparatives.
"We continue to focus on our key initiatives whilst ensuring we maintain our unique offer of tremendous value for money, combined with an unrivalled range and great service."
