The Jay-Be 2000 Hybrid e-Pocket TRUECORE Eco-Friendly Mattress is soft and cosy, and plenty of owners love it. The unhappy owners report it sagging and softening within weeks. That would put me off. Avoid it if you're heavier, have a bad back or want a mattress that holds its shape for years.
Two layers of springs and plenty of fibre
Jay-Be builds it with a deep e-Pocket spring core and a layer of micro pocket springs above, then rebound and advanced e-Fibre layers, a 3D spacer layer for airflow, a cushioned border and a quilted knitted cover. It's rolled for delivery, single-sided with turning handles, 23cm deep and rated soft to medium. Mattress Online lists it as approved by the National Bed Federation.
The eco claim is Jay-Be's own: fibre layers made with less land and water than traditional fillings. I'd like to see a named certificate before giving "eco-friendly" much weight. The micro springs add to the spring total; the deep springs underneath do the supporting.
Ordinary sheets fit, if it reaches its full length
At 23cm it takes ordinary fitted sheets, as long as it grows to full size once it's unrolled. Mattress Online sells it from single to king, with no super king, and allows 2cm either way on the dimensions. A few owners describe a bigger shortfall than that, with a gap at the frame and loose bedding. I change the sheets every Sunday without fail, and a fitted sheet that won't stay on its corners would drive me up the wall.
Measure it the day you unroll it and again once it has settled, and if it's still short by more than they allow, tell them while the mattress is new. There's no flipping it, so you swing it round end to end instead, and the handles are there for exactly that. It's also foam free, with a salt-based fire treatment, which is good news if you've been trying to keep foam out of your bed.
The complaint that would put me off
Sagging is what the unhappy owners keep coming back to. One says it sagged within a week, and a replacement did the same; another says all the support had gone by two months; a third, who isn't heavy, says it dips when you sit on it. Some find it unsupportive for a bad back. Early sagging is the complaint I take most seriously; it would stop me buying it for a main bed.
The happy owners describe a super-comfortable, soft mattress; a spare-room bed is where I'd use it. If you buy it, rotate it from the first week.
Mattress Online will swap it, if you bought the protector
Mattress Online's comfort trial gets you a different mattress, not a refund, and only if one of their own protectors went in the same order. They also expect you to give it a settling-in period before they'll talk swaps. One owner came to this mattress that way: their first choice felt firmer than they wanted, customer services talked them through a softer pick, and the swap was quick. That fits my view of the shop: honest prices, and returns that do what they say. Add the protector at checkout if you want the trial.
Front-door delivery is free. Room of choice and having your old mattress taken away both cost extra.
I'd rather turn an Aspire
For about the same money at the same shop, I'd buy Aspire's Pocket+ 1000 Wool and Cashmere. It's rolled and just as deep, but it has two sleeping sides and wool in the fillings. To my mind wool sleeps cooler and wears well. Turning shares the wear, which is what I'd want from a soft bed when the Jay-Be's owners are talking about dips.
The Aspire is rated medium, and a couple of its owners found it softer than that. The Jay-Be is still the softer of the two. My grumble is the Aspire's tufting, which pulls little dimples into the surface. It also has a layer of reclaimed foam in it, so the Jay-Be wins that round for anyone shopping foam free.
Where I'd put the money instead
If you want soft with staying power, choose a pocket-sprung mattress with a firmer support unit and a latex or wool comfort layer. For a turnable pocket-sprung budget bed, the Shire Spectrum Luminaire Pocket 3000 is medium-firm and turns.
