We estimate there are about 200 mattress shops in Singapore. How do you choose from them all? Certainly, shop size counts as you wouldn’t want a wasted trip exploring a small shop with limited offerings, and then another. 

We show you where to find the 5 largest mattress shops in Singapore, sorted by size. 

1. King Koil & Ashley Furniture Megastore — 12 Jalan Kilang Barat (≈ 30,000 sq ft)

This six-storey building commands over 30,000 sq ft of space, making it a one-stop destination for both King Koil’s mattress innovations and Ashley’s full furniture line. 

Visitors can test more than 40 King Koil mattress models, including premium and hotel-collection lines, on the top floor. Go through mattress one by one to find the one that suits your sleeping posture, your preference for soft or firm beds, and the feel of it on your skin. 

As King Koil’s flagship gallery, this store is not just about volume — it demonstrates our brand’s expertise in sleep technology and its authoritative status in Singapore’s mattress industry.
