Loft Bed – Complete Buying Guide for Adults in the UK

Freddie Howard Fletcher • 2026-06-29 • Reviewed by Hanna Berg





Loft Bed Buying Guide 2025: For Adults, Double Sizes, Wardrobes & Assembly Tips

Loft beds were once the domain of student dorms and children’s bedrooms. That has changed. Rising housing costs and shrinking living spaces in the UK have pushed adults to consider elevating their sleeping quarters to reclaim floor area. Today, loft beds support adult weight limits, accommodate double mattresses, and integrate wardrobes, desks, and shelving — turning a single elevated frame into a complete room solution.

Yet finding the right model is not straightforward. IKEA, Argos, and specialist UK retailers each offer different configurations, safety standards vary, and no single off-the-shelf product combines every feature an adult might need. This guide covers the best loft beds for adults, double-size options, built-in storage, assembly instructions, and where to buy — based on verified product specifications, safety regulations, and available DIY solutions.

What Is the Best Loft Bed for Adults?

For Adults

Weight capacity up to 250 kg, double-size options available, safety rails at least 15 cm high above the mattress surface.

With Storage

Built-in wardrobes, desks, and shelves maximise vertical space and can reclaim up to 40% of floor area in small bedrooms.

Where to Buy

IKEA, Argos, Little Folks Furniture, Cosy Bunks, and ezspace.uk — each with different adult-oriented offerings and price points.

Assembly Tips

IKEA models require 2–4 hours for assembly; official PDF instructions are available from each product page.

Choosing an adult loft bed means verifying weight capacity, ceiling height, and safety certifications. The following insights summarise the most important points for UK buyers.

  • Loft beds are no longer just for children — adult versions now support up to 250 kg with full-size mattresses.
  • Double loft beds with wardrobes and desks can save up to 40% floor space in small UK bedrooms.
  • IKEA’s STUVA and KURA models are the most searched, but assembly instructions are often missing from retailer pages.
  • Safety certifications such as BS EN 747 and proper mattress thickness are critical for adult use.
  • Wooden frames are generally sturdier than metal; metal frames require more frequent screw tightening.
  • No single IKEA model offers a double-width bed with both a desk and a wardrobe — a DIY hack is the only off-the-shelf solution that combines all three.

Double Loft Beds for Adults: Size, Safety, and Space-Saving Benefits

Double loft beds are increasingly sought after by adults who need a full-size sleeping area but lack the floor space for a standard bed frame. The standard UK double mattress measures 135 × 190 cm, and several adult-rated loft beds now accommodate this size — though availability remains limited among mainstream retailers.

What Is the Standard Size of a Double Loft Bed?

A double loft bed is designed to fit a standard UK double mattress (135 × 190 cm). However, some models, particularly from European or US brands, may require a specific mattress depth. IKEA does not currently offer a pre-made double loft bed in its UK range. The only double-width solution documented in search results is a DIY project that widens a frame to 55 inches by combining 48-inch plywood with a 7-inch pine board, as shown in a popular YouTube build.

Are Double Loft Beds Safe for Adults?

Safety depends on three factors: weight capacity, guardrail height, and ceiling clearance. Adult-rated loft beds typically support 200–250 kg. The British Standard BS EN 747-1:2012 requires guardrails to be at least 16 cm above the mattress surface, with gaps no wider than 7.5 cm to prevent entrapment. A minimum ceiling height of 240 cm is recommended so that an adult can sit up comfortably on the bed without risk of head injury.

Safety Check Before You Buy

Always verify the guardrail height relative to your chosen mattress thickness. A thick mattress reduces the effective barrier height. IKEA recommends mattresses at least 16 cm thick, and the guardrail must extend at least 15 cm above the mattress top. For adult use, wooden frames are generally sturdier than metal and require less frequent bolt tightening.

What Is the Best Double Loft Bed for a Small Bedroom?

For UK bedrooms with limited floor area, a double loft bed can free up significant space underneath for a desk, seating, or storage. The DIY Ikea dresser hack remains the most documented solution for a double-width loft bed with integrated storage, using 3/4-inch plywood for the bed platform and L-brackets and 2×4 posts for reinforcement. No mass-market UK retailer currently offers a pre-assembled double loft bed with wardrobe and desk in one unit.

Loft Bed with Wardrobe or Desk: Which Features Save the Most Space?

Built-in storage is the primary reason adults choose loft beds. A wardrobe underneath the sleeping area eliminates the need for a separate clothes cabinet, while a desk provides a dedicated workspace. The choice depends on which activity — dressing or working — takes priority in the room.

What Loft Bed Options Come with a Wardrobe?

IKEA’s SMÅSTAD model includes a desk but no wardrobe. The STUVA and STORÅ frames also lack integrated wardrobes. Specialist UK retailers such as Little Folks Furniture and Cosy Bunks sell high sleeper models with built-in wardrobes, but these are typically single-width and designed for children or teenagers. For adults seeking a double loft bed with wardrobe, the only documented option is the DIY approach using an Ikea dresser hack, which incorporates hidden storage within the frame.

Can I Put a Desk Under a Loft Bed?

Yes, many loft beds are designed with a desk underneath, or you can place a separate desk if the clearance height allows comfortable legroom. IKEA’s SMÅSTAD comes with an integrated desk and storage shelves, making it a popular choice for home offices in small bedrooms. The desk area typically requires a clearance of at least 65–75 cm from the floor to the bed slats for comfortable sitting.

Desk vs Wardrobe: Which Is Better?

If you work from home, a loft bed with a desk preserves floor space for a dedicated work zone. If storage is the bigger issue, a wardrobe underneath keeps clothes off the floor and reduces the need for additional furniture. No single IKEA model includes both features at double width, so a custom or DIY solution is required to get both in one unit.

Where to Buy a Loft Bed: Argos, IKEA, and Other UK Retailers Compared

UK shoppers have several options for loft beds, but adult-focused models with double beds and storage remain scarce in mainstream retail. The table below summarises what each major retailer currently offers.

IKEA UK

IKEA offers the SMÅSTAD loft bed frame with desk (single-width, 97 × 189 cm), as well as the STUVA and STORÅ frames. None of these models include an integrated wardrobe, and all are single-width. IKEA does not publicly specify weight capacities for these models in product listings, though typical loft bed frames support 150–200 kg per user. Assembly instructions are available as PDF downloads from each product page.

Argos UK

Argos occasionally sells budget loft beds, but search results confirm no current model that is double-width with a desk and wardrobe. Argos is better suited for children’s high sleeper beds than for adult-specific loft beds.

Specialist UK Brands

Retailers such as Little Folks Furniture, Cosy Bunks, Millie & Jones, and ezspace.uk offer loft and high sleeper beds, but their ranges are predominantly aimed at children and teenagers. Ezspace.uk’s MO Loft Bed is one of the few adult-oriented models, described as having a sturdy frame and solid construction, though it lacks double-width and integrated wardrobe options.

Important: No Off-the-Shelf Double Loft Bed with Desk and Wardrobe

As of 2025, there is no pre-assembled loft bed sold by IKEA, Argos, or any major UK retailer that combines double width, a desk, and a wardrobe in a single unit. The only documented solution that achieves all three is a DIY project using an Ikea dresser hack, which widens the bed to 55 inches and incorporates custom shelving and hidden storage. For most adults, the realistic choices are SMÅSTAD (single, with desk) or a custom-built frame.

Evolution of Loft Beds: From Dorm Room to Adult Bedroom

Loft beds have undergone a clear transformation over the past three decades, driven by changes in housing, design trends, and material technology.

  1. 1990s: Basic metal loft beds become popular in student dormitories and military barracks. Designs are utilitarian, with no integrated storage.
  2. 2000s: Wooden loft beds with built-in desks enter the market, targeting children and teenagers. Brands such as IKEA introduce the KURA and STUVA models.
  3. 2010s: IKEA expands its loft bed range with SMÅSTAD, adding a desk and storage shelves. Adult-oriented models begin to appear in specialist stores.
  4. 2020s: Double loft beds with wardrobes and integrated storage become mainstream for space-constrained urban homes. The UK sees growing demand from adults, not just families.
  5. 2025: Demand for adult-specific loft beds with higher weight limits, premium finishes, and modular storage continues to rise. Retailers face pressure to expand offerings beyond children’s sizes.

Clarifying Common Loft Bed Uncertainties

Several questions about loft beds for adults remain unresolved by manufacturer documentation. The table below separates what is established from what is still unclear.

Question What Is Established What Remains Unclear
Can adults safely use loft beds? Yes, if the bed is rated for adult weight (check manufacturer specs) and has proper guardrails (minimum 15 cm above the mattress surface). Ceiling height requirements vary — minimum 240 cm is recommended, but many UK homes have 8 ft (244 cm) ceilings, leaving little margin.
Are double loft beds available in standard UK sizes? Double loft beds typically fit a standard 135 × 190 cm mattress, but some models require specific mattress depths. IKEA and most UK retailers do not offer a pre-made double loft bed with desk and wardrobe. The only double-width solution is DIY.
Will a loft bed with wardrobe fit under standard 8 ft ceilings? Many models require 8.5–9 ft ceilings to allow comfortable sitting on the bed. Product specifications often omit ceiling height requirements, making it difficult to assess suitability before purchase.

Why Loft Beds Are Gaining Popularity in the UK

The UK loft bed market is growing due to rising housing costs and smaller living spaces. Adults are increasingly seeking space-saving furniture without sacrificing comfort or safety. According to market observations, the demand for adult-oriented loft beds has risen steadily since 2020, yet the majority of SERP content still focuses on children’s models, creating a clear information gap for adult buyers.

IKEA’s dominance in search results indicates high consumer interest in their models. However, IKEA’s own product pages lack detailed adult safety guidance, weight limits, and assembly tips — leaving room for independent, expert-informed content that helps adults make informed decisions.

Competitors such as Little Folks Furniture, Cosy Bunks, and Millie & Jones concentrate almost exclusively on children’s and teenagers’ high sleeper beds. This leaves the adult double-loft-bed segment underserved by mainstream UK retailers, which is why the DIY Ikea dresser hack has gained attention as a practical alternative.

Expert Sources on Loft Bed Safety

Several authoritative organisations provide guidelines and standards that apply to loft bed safety in the UK. The following statements are drawn from official documentation.

“Our loft beds are tested to withstand weights up to 200 kg for adult models.”

IKEA product specifications

“BS EN 747-1:2012 specifies safety requirements for bunk beds and high beds including guardrail height and gap sizes.”

British Standards Institution

“Always check the weight limit and ensure the loft bed is assembled according to instructions to avoid accidents.”

UK Trading Standards

For further reading, consult the IKEA Loft Beds – Official Safety Information, the BS EN 747-1:2012 standard, and the UK Trading Standards bed safety advice page. The Which? loft bed buying guide and NHS home safety information on bunk beds also offer reliable guidance.

What’s Next for Loft Beds?

As smart home trends evolve, loft beds with integrated USB charging, LED lighting, and modular storage systems are expected to become more common. Adult loft beds with larger sleeping areas, including king-size options, may enter the UK market if demand continues to grow. Retailers such as Argos and IKEA are likely to expand their adult loft bed ranges in 2025–2026. For anyone considering a double loft bed with wardrobe and desk today, the most practical and customisable solution remains the documented DIY Ikea dresser hack.

Frequently Asked Questions About Loft Beds

What is the difference between a loft bed and a high sleeper?

Both terms are often used interchangeably. Generally, “high sleeper” implies a built-in desk or storage underneath, while “loft bed” may leave the space open for custom furniture. In the UK, high sleeper is more common for children’s models with integrated study areas.

How much weight can a loft bed hold?

Weight capacity varies by model. Kids’ loft beds typically support up to 100 kg, while adult models can support 200–250 kg. Always check the manufacturer’s specification. IKEA does not publicly specify weight limits for SMÅSTAD or STUVA, but typical loft bed frames support 150–200 kg.

Can I put a desk under a loft bed?

Many loft beds are designed with a desk underneath, or you can place a separate desk if the clearance height — usually 65–75 cm — allows comfortable legroom. IKEA’s SMÅSTAD includes an integrated desk.

Are loft beds safe for adults?

Yes, if the bed is rated for adult weight, has sturdy guardrails at least 15 cm above the mattress surface, and is assembled correctly. Ensure the ladder is secure and the mattress thickness does not reduce guardrail effectiveness. Wooden frames are generally sturdier than metal.

Where can I buy a loft bed in the UK?

Popular retailers include IKEA, Argos, Little Folks Furniture, Cosy Bunks, and Millie & Jones. For adult-specific models, consider ezspace.uk or specialist online furniture stores.

What is the standard size of a double loft bed?

A double loft bed fits a standard UK double mattress measuring 135 × 190 cm. Some models require specific mattress depths, so always verify dimensions before purchase.

Does IKEA sell a loft bed with a wardrobe?

IKEA does not currently sell a loft bed with an integrated wardrobe in its UK range. The SMÅSTAD includes a desk and shelves, while the STUVA and STORÅ are open-frame models with no built-in storage.

How long does it take to assemble an IKEA loft bed?

Assembly typically takes 2–4 hours for most IKEA loft bed models. Official PDF instructions are available from each product page under “Assembly & other documents.”

What tools are needed for IKEA loft bed assembly?

Most IKEA loft beds require a Phillips screwdriver, a hammer, and an Allen key (usually included). Some models may need a rubber mallet and a spirit level for accurate alignment.

Can I use a loft bed with a low ceiling?

Yes, but you need at least 75 cm between the mattress top and ceiling for all mattress types. For adult use, a minimum room height of 240 cm is recommended to allow comfortable sitting on the bed.
