Assessed from the specification published by MattressNextDay, captured September 2026, and from regular price comparison across our UK retail partners.
If you sleep on your back or front and like a firm surface, this mattress makes a strong case at the price. The 1400 pocket springs work completely independently, which means less motion transfer if you share a bed and support that adapts to where you actually need it. The Eco Comfort Fibres layer is breathable, 100% recyclable and designed to keep you cooler, a genuine plus if you tend to overheat at night. Allergy sufferers get the reassurance of the Allergy UK Seal of Approval and hypoallergenic fillings, and it's vegan friendly too. Yes, it's a fairly simple build with polyester rather than natural fillings, but at £289 to £509 that's a fair trade. Sizes run from UK Single to UK Super King.
Key Features & what's inside
- Cover. A breathable Belgian damask fabric cover. It lets air move through the surface, which helps keep the sleeping surface fresher.
- Comfort Fillings. Resilient polyester comfort fillings with layers of soft white fibres. These sit between you and the springs, which means a softer initial feel that helps alleviate pressure points.
- Eco Comfort Fibres™. Breathable, sustainable fibres that are 100% recyclable. They've been scientifically proven to keep you cooler while you sleep, a helpful layer if you run warm at night.
- Support System. 1400 pocket springs, each mounted in its own separate fabric pocket. They work completely independently, which means support that follows your shape and less disturbance when a partner moves.

Who's it NOT for?
This is a firm mattress, so it's not the right pick if you're a lightweight side sleeper or you simply prefer a softer, more cushioned feel. The comfort layers are polyester rather than memory foam or natural fillings, so anyone after a deep, contouring hug should look elsewhere.
Rest Assured Venice Ortho 1400 Pocket Mattress
View all mattresses
Is the Rest Assured Venice Ortho 1400 firm or soft?
It's rated firm. That suits back and front sleepers who want plenty of support, and heavier sleepers generally. If you sleep on your side and are on the lighter side, you may find it a little too solid for comfortable pressure relief at the shoulders and hips.
How many springs does the Venice Ortho 1400 have?
It has 1400 pocket springs, each housed in its own fabric pocket. Because they work independently, the springs respond to your body individually, which means better pressure relief and less movement transferring across the bed when a partner shifts position.
Does the Rest Assured Venice Ortho 1400 come with a guarantee?
Yes, it comes with a Rest Assured 5 year manufacturer's guarantee. No trial period is mentioned on the retailer listing we sourced, so check returns terms with your chosen retailer before you buy.
Is the Venice Ortho 1400 good for allergy sufferers?
It's a strong option. The mattress is hypoallergenic and carries the Allergy UK Seal of Approval, an independent endorsement rather than a marketing claim. It's also vegan friendly, with polyester and fibre fillings rather than wool or other animal-derived materials.
What sizes does the Rest Assured Venice Ortho 1400 come in?
It's available in UK Single, Small Double, Double, King and Super King, priced from £289 to £509 depending on size. MattressNextDay lists free next day delivery to mainland UK, though some addresses may incur a small fee. Delivery terms will differ if you buy elsewhere.
