Assessed from the product page published by Mattress Online, captured September 2026, and from regular price comparison across our UK retail partners.
The main draw here is the combination of a genuinely soft feel with hybrid support. Pocket springs move independently, which means less disturbance when a partner shifts in the night, while the box top adds a settled, cushioned surface from the first night rather than needing to bed in. At £584 to £954 it sits at a reasonable price for a branded hybrid, and Silentnight is a long-established UK name. The 5 year guarantee listed by the retailer offers some reassurance, though it's shorter than some brands provide. Suits side sleepers and lighter bodies well, although anyone who prefers a firmer, more supported feel should look elsewhere in the range.
Key Features & what's inside
Awaiting up to date specifications. Please check back later.
Who's it NOT for?
This is a soft mattress, so it's unlikely to suit stomach sleepers or heavier bodies who need firmer support to keep the spine aligned. Box top designs also can't be flipped, only rotated. If you like sleeping on top of your mattress rather than settling into it, choose a firmer model.
Silentnight UltraGel 3000 Mirapocket Box Top Softer Mattress
How firm is the silentnight ultragel 3000 mirapocket box top?
It's rated soft. Combined with the box top, a cushioned layer sewn onto the sleep surface, you can expect a plush, sink-in feel. That tends to suit side sleepers and lighter people, but it's a little forgiving for those who need firm support.
What sizes does the silentnight ultragel 3000 come in?
It's available in UK Single, Small Double, Double and King sizes, with prices ranging from £584 to £954 depending on the size you choose.
Does the silentnight ultragel 3000 have a guarantee?
The retailer lists a 5 year guarantee with this mattress. Check the terms at the point of purchase, as guarantee cover can vary by seller.
Is the silentnight ultragel 3000 a pocket sprung mattress?
Yes, it's a hybrid that uses Silentnight's Mirapocket springs. Pocket springs respond individually to pressure, which means better contouring to your body and less motion transfer across the bed than open-coil designs.
