Cheap Silentnight Mattresses – Best Options Compared

It mostly comes down to how you sleep.

Side sleepers need a mattress that cushions the hips and shoulders. The Memory 1000 Mirapocket is our pick here. The memory foam layer softens and moulds to your shape, taking the edge off those pressure points. The 800 Mirapocket works well too if you prefer a firmer feel.

Back sleepers need even support along the whole spine. A medium to firm mattress is usually ideal. Firm enough to keep your back in alignment, not so hard that it creates pressure. Both the 800 Mirapocket and the Ortho Dream Star work well here, depending on how firm you like it.

Front sleepers tend to need a firmer surface to stop the hips and lower back sinking into an uncomfortable position. The Ortho Dream Star is the natural fit.

Not sure, or you move around a lot? The 800 Mirapocket is the safe all-rounder. Medium to firm suits most sleeping styles and most body types.

Two different spring systems, both exclusive to Silentnight.

Miracoil is an open coil system. The springs run vertically through the mattress rather than side to side, and the whole unit is split into three support zones. Firmer and more consistent across the surface, and generally less expensive to make. That’s the spring system in the Ortho Dream Star.

Mirapocket is a pocket spring system. Each spring sits in its own fabric pocket and moves independently. It responds to your body shape rather than pushing back uniformly. Better for couples (less disturbance if one of you is a wriggler), and generally more comfortable for a wider range of sleepers. That’s what the 800 and Memory 1000 use.

From Argos and Dunelm to Amazon, MattressOnline and MattressNextDay, Silentnight is sold everywhere, and prices vary more than you’d expect.

MattressOnline and MattressNextDay are our go-to recommendations. Both price Silentnight competitively and both offer a 60-night comfort trial. Sleep on it for at least 30 nights, and if it’s still not right, you can swap it. That’s a genuinely useful safety net when you’re buying a budget mattress online without trying first.

Amazon is worth a look too, especially during sales. Just check whether it’s sold by Amazon or Silentnight directly. Third-party sellers on Amazon can have different (and sometimes worse) return policies.

It’s also worth checking sale and clearance sections on retailer sites. Because Silentnight regularly refreshes their ranges, older models often get discounted to make room for new ones. You won’t always find something, but when you do it can be a meaningful saving.

The same Silentnight mattress sometimes appears under slightly different names on different retailer sites. The Ortho Dream Star on MattressOnline, for example, is listed as the Silentnight Miracoil Ortho on Amazon. Some are genuine retailer-exclusive models; others are identical mattresses with a tweaked name.

If you’re comparing across sites and something looks familiar, check the images and specs: spring type, spring count, firmness rating, and fillings. If they match, it’s the same mattress.

Yes, and that’s not something we’d say about every brand. Every Silentnight mattress is tested before it goes to market, and even their entry-level models use proper spring systems and consistent UK manufacturing. You’re not taking a punt on an unknown brand with a fancy name. You know what you’re getting.

The Ortho Dream Star Miracoil is our pick. It’s Silentnight’s firmest mattress in this range, with a 3-zone spring system designed for consistent support across your back and joints. A lot of back pain sufferers find that a properly firm, supportive mattress helps more than a softer one. However, everyone is different, which is why a 60-night comfort trial from MattressOnline is worth having.

If you buy from a specialist retailer like MattressOnline or MattressNextDay, you get a 60-night comfort trial. Sleep on it for at least 30 nights to let your body adjust, and if it’s still not working for you, you can swap it. That’s a much better safety net than the 30-day return window you’d typically get from Amazon or a department store.

All three on this page come with a 5-year guarantee from Silentnight. Rotate them regularly and use a mattress protector and they should comfortably last 7 to 10 years.
