Can a mattress help with back pain?
A mattress can make a real difference to comfort and support, but it is not a treatment or cure. The useful question is whether the mattress keeps you supported enough to help your body feel aligned while still relieving pressure where you need it most. In the example shortlist, that means comparing medium-to-firm Luna 4000 Support Gel Memory Pocket Hybrid Mattress from £389 to £799, Harrison Spinks Bordley Natural 2750 Pocket Firmer Mattress from £595 to £1,185, and Luna 6000 Support Gel Memory Pocket Hybrid Mattress from £499 to £1,069 rather than assuming one format suits every back.
What to look for in a back-pain mattress
Start with firmness and feel, then look at the materials under the cover. A medium-firm mattress is a common starting point, but the right level depends on how much contouring you want and whether you prefer a more responsive or more cushioned surface. For these examples, the Luna models pair pocket springs with gel memory foam and mention cooler-sleep comfort, while the Harrison Spinks mattress uses pocket springs with wool comfort fillings and a firmer-positioned feel, so the trade-off is foam-led cushioning versus a more natural, spring-led build.
Which mattress types are often recommended
Hybrid and pocket sprung mattresses solve the back-comfort question in different ways. The Luna 4000 and Luna 6000 are hybrids, combining pocket springs with gel memory foam, which may suit shoppers who want spring support plus a softer comfort layer and are comparing temperature-comfort messaging as part of the decision. Harrison Spinks Bordley Natural 2750 is a pocket sprung mattress with wool fillings, which may appeal if you want a more traditional support feel and less emphasis on foam sink.
How sleeping position changes the choice
Sleep position matters as much as the label on the product page. Side sleepers usually need more cushioning around the shoulders and hips, so a medium-firm hybrid can feel more forgiving than a firmer pocket sprung option; back and stomach sleepers often want a steadier surface that resists sagging. That makes medium-firm a sensible starting point, not a rule. If you are unsure, compare how each mattress is described for support and comfort, then check whether the size and firmness fit the way you actually lie down.
When to replace an old mattress
A mattress that no longer feels even or supportive can stop being a good fit long before you notice a dramatic issue. Visible wear, a change in how the surface supports you, or a build that no longer matches your sleep position are all reasons to look again, especially if your current mattress is much softer or firmer than you now prefer. The value case is stronger when the replacement also gives you a 100-night comfort trial, like all three examples here, plus a guarantee that matches how long you expect to keep it.
What the retailer comparison suggests
The shortlist is useful because it shows three clear ways to shop for back-comfort support: the lower-priced Luna 4000 at £389-£799, the mid-priced Luna 6000 at £499-£1,069, and the higher-priced Harrison Spinks at £595-£1,185. review details are visible but modest across the group, with 4.7/5 from 28 reviews for the Luna 4000, 4.5/5 from 11 reviews for the Luna 6000, and 4.8/5 from 10 reviews for the Harrison Spinks, so the better move is to compare the product details rather than over-read the ratings. All three list a 100-night comfort trial, but the Luna models carry a 10-year guarantee while the Harrison Spinks model shows 5 years, which is a useful value check when prices are close.
How to turn the advice into a shortlist
Use the shortlist by shopper scenario, not by assuming one mattress is universally better. If you want the lowest entry price and a hybrid feel, the Luna 4000 is the cheapest example; if you want a step-up hybrid with similar medium-to-firm positioning, the Luna 6000 sits in the middle; if you prefer a firmer pocket sprung option with wool comfort fillings and a more natural build, the Harrison Spinks is the clearest alternative. Before buying, check latest price and availability, confirm the size you need is in stock, and make sure the depth works with your bed frame, bedding and any topper you already own.

Firmness questions
Is a firm mattress always best for back pain?
No. Many shoppers do better with medium-firm support rather than a very firm feel. Side sleepers usually need more cushioning, while back and stomach sleepers often prefer a steadier, firmer surface.
Are memory foam mattresses or hybrid mattresses better for back pain?
It depends on the feel you want. Hybrid mattresses like the Luna 4000 and Luna 6000 add pocket springs under a gel memory foam comfort layer, while pocket sprung options like Harrison Spinks Bordley Natural 2750 lean more toward a traditional spring-led feel with wool fillings.
What should I check before choosing a mattress for a back-comfort search?
Check firmness, construction, size options, mattress depth and bed-frame fit, then compare trial and guarantee details. The three examples here all show a 100-night comfort trial, but the Luna models have a 10-year guarantee versus 5 years for the Harrison Spinks.
