Assessed from Mattress Online's published specification for this mattress, captured September 2026, and from regular price comparison across our UK retail partners.
Choose the HydroShield Classic if you need a practical, wipe-clean mattress at a genuinely low price. The water-resistant cover makes it a sensible pick for guest rooms, rental properties or student lets, where accidents happen and durability matters more than luxury. The Ecofoam core has natural rebound, which means it recovers its shape between sleepers rather than developing a lasting body impression. At 10cm deep it's a slim mattress, so this isn't the one for your main bedroom if you want a plush, deep feel. But for occasional or commercial use, the 100-night trial, 10-year guarantee and free front-door delivery make it a low-risk buy.
Key Features & what's inside
- Ecofoam. A 10cm layer of Ecofoam made entirely from recycled materials, which means it supports a variety of body shapes while keeping waste out of landfill. It has natural rebound, so it returns to shape between sleepers rather than sagging where the last person lay.

Who's it NOT for?
At 10cm deep with a single foam layer, this isn't a mattress for everyday use as your main bed if you want deep cushioning or pressure relief. Heavier sleepers and dedicated side sleepers may find the medium to firm feel a little unforgiving. It's built for commercial settings first, comfort-seekers second.

Is the HydroShield Classic mattress waterproof?
It has a water-resistant cover rather than a fully waterproof one, which means it will cope with spills and moisture better than a standard fabric mattress. That's part of why it suits hotels, rentals and student accommodation, where easy cleaning matters.
How firm is the Mattress Online HydroShield Classic?
Mattress Online describes it as medium to firm. The 10cm Ecofoam core supports a variety of body shapes, although lightweight side sleepers may find it a little too firm for comfortable pressure relief on hips and shoulders.
Does the HydroShield Classic come with a trial and guarantee?
Yes. Mattress Online offers a 100-night trial and a 10-year guarantee, which is generous for a mattress starting at £139.00. That gives you a full season or more to decide whether it suits you.
What is the HydroShield Classic mattress made of?
It's a single 10cm layer of Ecofoam made from 100% recycled materials, finished with a water-resistant cover. It's handcrafted in the UK and meets BS 7177:2008 fire safety standards, including Ignition Source 5 for use in most commercial premises.
How much does delivery cost for the HydroShield Classic?
Delivery to your front door is free within 2 to 3 weeks across mainland England and most of Scotland, Wales and Northern Ireland. Delivery to a room of your choice costs £20, and old mattress removal is £35.
