Detailed construction information for the Komfi Unity Pocket 1000 is hard to come by, so if the layer-by-layer detail matters to you, it's slightly frustrating that Komfi doesn't publish a dedicated page for it. What we can say is that pocket springs, which move independently of each other, tend to reduce the ripple effect when a partner shifts position. On price alone, it sits comfortably at the budget end of the market.

Why should you choose this mattress?
The main draw here is value. This is affordable for a pocket sprung, boxed mattress, and the mattress-in-a-box format means it arrives compressed and rolled, which makes getting it up narrow stairs or into a small flat far easier than wrestling a full-size mattress. Pocket springs respond to each sleeper individually, which means less disturbance if you share a bed with a restless partner. The five-size range covers most UK bed frames, including the less common Small Single and Small Double.
Key features & layer details
Reflex foam top layer
A 3cm layer of high-density Reflex foam sits at the top of the mattress. It adds a layer of cushioning over the springs, so the surface feels softer than bare springs would.
Pocket spring core in Ecofoam
Traditional pocket springs, each moving independently, are encased in Ecofoam made from 100% recycled foam. Because the springs work separately, the mattress can respond to each sleeper, which means less disturbance from a partner's movement. The recycled foam is a plus if you prefer to cut down on waste.

Best suited for?
Budget buyers
The copy calls it affordable for a pocket sprung, boxed mattress, so it suits anyone wanting independent springs without paying at the top of the market.
Couples
Pocket springs move independently of each other, which means less ripple across the bed when a restless partner shifts position during the night.
Guest rooms
Arriving compressed and rolled in a box, it is easy to carry up narrow stairs, and its low cost suits a spare room.
Combination sleepers
Pocket springs respond to each sleeper individually, which suits people who change position often and want the mattress to react to each movement.
If you want full transparency before you buy, this isn't the easiest mattress to research: Komfi doesn't publish a dedicated specification page for this exact model, so details like depth and comfort layers aren't confirmed. Buyers needing a Super King should also look elsewhere, as sizes stop at King.
Save on an earlier or ex-display model
Some retailers still sell the earlier version of this mattress, or ex-display and returned stock at a lower price. These are the sizes where it costs less than the current model's best price.

FAQ's
How much does the komfi unity pocket 1000 cost?
It depends on the size you choose, and the price table on this page shows the current price for each size. It sits firmly at the budget end of the pocket sprung market, which helps explain its appeal to first-time buyers and those furnishing a spare room.
What sizes does the komfi unity pocket 1000 come in?
Five UK sizes are available: Small Single, Single, Small Double, Double and King. There's no Super King option, so if you have a larger frame you'll need to look at a different model.
Does the komfi unity pocket 1000 come rolled in a box?
Yes, it's a mattress in a box, so it arrives compressed and rolled. That makes delivery and manoeuvring it into the bedroom noticeably easier, particularly in flats or homes with tight staircases.
