Advice and buying guides
What is the number one best mattress?
Here at Mattress Online, our number one best-selling mattress is the Silentnight Ortho Dream Star Miracoil Mattress*. It’s been a customer favourite for the last four years, earning its place in our ‘Top 10 Recommended Mattresses for 2024’.
It's perfect if you’re looking for an extra firm mattress on a budget! The Ortho Dream Star features Silentnight’s innovative Miacoil springs - an interlocked spring system that provides consistent, orthopaedic support across the whole mattress for you and your partner.
This even support helps to take the pressure off your back, hips and joints to ease any discomfort you may be experiencing.
And with over 5,200 Feefo reviews* and an average review score of 4.6/5, you don’t just have to take our word for it.
