Customer Reviews
Good value on an ottoman bed
I needed a new bed and was looking for something with storage. Found an ottoman bed during their clearance sale. Got a decent percentage off the RRP, which made it a good deal. Delivery took 3 days which wasn't next day but still fine. Overall, I felt like I got my money's worth and the bed is solid.
Always reliable service
I ordered a Silentnight mattress again, a super king this time. They always deliver quickly, usually next day for me. It's comforting knowing what to expect, same good quality as my previous orders. They're consistent.

Hey, thinking about grabbing a Silentnight mattress from here. Anyone know if their 'free next day delivery' is actually reliable, like if I order today will it really be here tomorrow?
