Soft medium mattresses give you gentle, cushioned comfort without losing proper support underneath, making them a popular choice for side sleepers and anyone who finds firmer mattresses uncomfortable on the shoulders and hips. At Land of Beds, we've been helping people across the UK find the right mattress for over 50 years. Our soft medium range includes memory foam, gel, pocket sprung, and natural filling options, with prices starting from £139 and running through to premium natural fillings above £2,000. Free mainland UK delivery, our Price Promise Guarantee, and expert advice are included as standard.

Picking a mattress by feel alone is difficult when you're buying online, and firmness names mean different things depending on the brand. A soft medium mattress sits between soft and medium on the comfort scale, giving you that plusher, more cushioned feel on top while still keeping proper support underneath. At Land of Beds, we've spent over 50 years helping people match the right mattress to how they actually sleep, with no pressure to buy anything you haven't tried or asked about.
Three things determine whether a soft medium mattress will suit you. Get these right and the rest, cover fabric, brand, extras, is easy to work through.
| Factor | Why It Matters | What to Check |
|---|---|---|
| Sleeping position | Side sleepers generally benefit most from softer mattresses, since they cradle the shoulders and hips. Back and front sleepers often need firmer support. | Your usual sleeping position and whether you tend to change position through the night |
| Body weight | A heavier build can sink further into a soft medium mattress than a lighter build, changing how supportive it feels. | Your weight relative to the mattress's recommended range, if listed on the product page |
| Filling type | Memory foam, gel, natural fibres, and pocket springs all deliver softness differently, affecting temperature, bounce, and how the mattress feels over time. | Which filling type suits your temperature preference and budget |

The filling inside a soft medium mattress determines how it feels, how warm it sleeps, and how long that softness lasts. Here's a plain comparison of the fillings available in this range.
| Type | Key Features | Best For |
|---|---|---|
| Memory Foam | Contours closely to the body, strong pressure relief, can retain more heat than other fillings | Side sleepers wanting close-conforming pressure relief |
| Gel | Similar contouring to memory foam with a cooler sleep surface | Warmer sleepers who want a softer feel without overheating |
| Natural Fillings | Cotton, wool, silk, or cashmere layered over pocket springs, breathable and temperature-regulating | Sleepers wanting a more traditional, breathable feel |
| Pocket Sprung | Individually wrapped springs that move independently, reducing partner disturbance, paired with a soft comfort layer | Couples, and sleepers wanting responsive support beneath the softness |

In our showrooms, side sleepers who've spent years on a firm mattress are often surprised by how much pressure relief they were missing. It's usually the shoulders and hips that tell them first.
Your budget affects filling quality, spring count, and how long the mattress keeps its softness.
| Budget | What You Get | Best For |
|---|---|---|
| Under £500 | Entry-level memory foam or gel comfort layers over a simpler spring or foam base. Comfortable, but softness may reduce with regular use over time. | Guest rooms, first homes, occasional use |
| £500 to £999 | Better quality fillings, higher pocket spring counts, more durable comfort layers. Where most main bedroom buyers land. | Everyday use in a main bedroom |
| £1,000+ | Premium natural fillings, high pocket spring counts, superior build quality designed to hold their softness for longer. | Long-term investment, master bedrooms |
A higher-quality soft medium mattress tends to hold its comfort layer for longer, so it keeps that plush feel rather than flattening out within a couple of years.
Mike Murray, Land of Beds CEO: "A soft medium mattress lives or dies by the quality of its comfort layer. Spend a little more in the £500 to £999 range and you'll notice the difference in how long that softness actually lasts."

Not sure whether soft medium or firm is the right tension for you? Here's a plain comparison.
| Soft Medium | Firm | |
|---|---|---|
| Feel | Plush, cushioned surface with noticeable give | Minimal give, sleeps on top of the mattress rather than in it |
| Best for | Side sleepers, lighter builds, pressure relief | Back and front sleepers, heavier builds, those wanting more support |
| Pressure relief | Strong, especially at shoulders and hips | Lower, support is prioritised over cushioning |
Neither is objectively better, it depends on your sleeping position and body weight. Read our full guide: What Mattress Firmness Is Best for You?.

| Question | Answer |
|---|---|
| What's the best soft medium mattress to buy? | Depends on your sleeping position, body weight, and filling preference. Side sleepers and lighter builds tend to do best with soft medium. Use the quick decision guide above to narrow down by filling type. |
| Will any bed frame or divan base fit a soft medium mattress? | Yes, as long as the mattress size matches your frame or base exactly. Sprung mattresses perform best on a supportive slatted or divan base, so check your base is suitable before ordering. |
| Is old mattress removal available when I order? | Available on most models as a paid add-on, but not universal across the range. Check the individual product listing to confirm before you order. |
| How long should a soft medium mattress last? | Typically 7 to 8 years with regular use, though this varies by filling and build quality. Natural fillings and higher pocket spring counts tend to hold their comfort layer for longer. |
| What size soft medium mattress should I choose? | Match your mattress size exactly to your existing or new bed frame or divan base. See the size guide above for dimensions and room guidance. |
| Does a soft medium mattress come with a removable cover? | This varies by product, some are removable and washable, others are not. Check the individual listing to confirm before ordering. |
| Does a soft medium mattress require assembly? | No assembly is needed. If your mattress is delivered rolled and vacuum-packed, allow it time to fully expand before use, check the listing for guidance. |
| Do you offer free delivery on soft medium mattresses? | Yes. Free UK delivery on orders over £100. Some further out postcodes may incur a charge. See our delivery information for details. |
| Can I buy a soft medium mattress on finance? | Yes. 0% finance is available on eligible orders. See our finance page for terms and eligibility. |
| What's the difference between soft medium and medium firm? | Soft medium has a plusher, more cushioned top layer with slightly less underlying support. Medium firm sits further towards the firmer end, with less give and more support for back and front sleepers. |
| Is memory foam or a natural filling better for a soft medium feel? | Memory foam gives closer, more contouring pressure relief but can sleep warmer. Natural fillings offer a softer feel with better breathability, usually at a higher price point. Neither is better, it depends on your temperature preference and budget. |
