A century after its creation, the Black LC4 Chaise Longue remains one of the most recognisable symbols of modernist furniture. Its long reclining cradle, tubular metal frame and sculptural profile make it very different from an ordinary lounge chair.
Now, design-conscious buyers in the UK and EU can bring that distinctive aesthetic into contemporary interiors without automatically stepping into the price range associated with premium designer furniture.

Why the Black LC4 Chaise Longue Still Stands Out
The LC4 Chaise Longue was designed in 1928 by Le Corbusier, Pierre Jeanneret and Charlotte Perriand and exhibited at the Paris Salon d’Automne in 1929.
Its design is based around a simple but effective concept: instead of forcing the body into the conventional proportions of an armchair, the LC4 allows the user to recline across a curved, adjustable support.
The result is furniture that looks architectural while remaining highly functional.
The black version is especially striking because the dark upholstery creates a strong contrast with the polished metal structure.
It can work as:
- A living-room statement piece
- A reading chair
- A bedroom relaxation chair
- A home-library chaise
- A contemporary office lounge
- A luxury apartment accent
- A boutique-hotel seating feature
The design’s historical significance is documented by the Museum of Modern Art’s LC4 collection record, which identifies the designers and records materials including chrome-plated steel, fabric and leather.
Current Interior Units LC4 Black Sale Price
The current Interior Units listing shows the Chaise Lounge LC4 Le Corbusier Chair-Black at €635, reduced from €950. The listing also shows a 5-star rating based on 13 reviews.
Current Price Comparison
| Price Point | Amount | Saving |
|---|---|---|
| Listed/original price | €950 | — |
| Current Interior Units sale price | €635 | €315 |
| Additional first-order discount | 5% | €31.75 |
| Effective first-order price* | €603.25 | €346.75 total saving |
| Delivery | Free UK & EU | Additional delivery saving |
*Calculated by applying the advertised 5% first-order code to the currently displayed €635 sale price. Confirm the final checkout total and eligibility before payment.
This creates a useful distinction between the existing sale price and the additional first-order promotion.
Instead of presenting the promotion as though the chair is simply 5% off €950, the more accurate calculation is:
€635 sale price → 5% first-order discount → €603.25
That is a stronger value proposition for a new Interior Units customer.

What Makes the LC4 Different From a Normal Lounge Chair?
The biggest difference is its relationship with the body.
A conventional lounge chair generally combines a fixed seat, back and legs. The LC4 takes a different approach.
Its reclining cradle is designed to move within the supporting structure, allowing the user to change the angle.
That creates three important benefits:
Reclining flexibility
You can adjust the position to suit different relaxation preferences.
Distinctive ergonomics
The curved form supports a more extended reclining posture.
Visual character
Even when nobody is sitting on it, the LC4 functions as a sculptural object.
This combination is why the Le Corbusier LC4 Chaise Longue has remained relevant across different generations of interior design.
Black Leather: Why Choose It?
Black is arguably the most recognisable upholstery choice for the LC4.
It gives the chaise a stronger architectural appearance and works particularly well with metallic finishes.
A black leather LC4 chaise longue can complement:
- White walls
- Concrete
- Walnut
- Oak
- Glass
- Marble
- Dark flooring
- Neutral rugs
- Contemporary artwork
It is also easier to integrate into monochrome interiors than warmer leather colours.
If your room already contains cream, beige or natural wood furniture, the black LC4 can become a deliberate contrast piece.
LC4 Chaise Longue Price: What Should Buyers Compare?
Price alone doesn’t tell you whether an LC4-style chair represents good value.
Before comparing two products, look at the specifications.
Upholstery
Is the material clearly identified?
Terms such as “premium leather” are less useful when the actual leather type isn’t explained.
Frame
Look for information about the metal structure, finish and stability.
Cushion
Check the filling material, thickness and construction.
Reclining mechanism
The adjustable cradle is central to the LC4 concept, so smooth movement and secure positioning matter.
Warranty
A clear warranty gives buyers additional confidence when purchasing a large piece of furniture online.
Delivery
Large furniture can be expensive to ship, making free delivery an important part of the overall value.
Is the Interior Units Price Competitive?
The current €635 sale price positions the Interior Units Black LC4 well below the €950 displayed reference price on its listing.
But buyers should compare products on a like-for-like basis.
For example:
| What You’re Comparing | Why It Matters |
| €635 LC4 reproduction | Accessible designer-inspired option |
| €950 reference/list price | Shows the current listed reduction |
| First-order €603.25* | Additional promotional saving |
| Premium licensed LC4 | Different category with different provenance |
| Cheap lookalike | May use different materials/construction |
*Before any other applicable checkout adjustments.
The goal should not be to claim that a reproduction is identical to an officially licensed original.
Instead, the value proposition is straightforward:
recognisable modernist design + accessible pricing + current sale + first-order discount + free delivery
Authentic LC4 vs Designer-Inspired Reproduction
This is an important distinction for an honest buying guide.
The original LC4 design has a well-documented history, and authorised versions exist in the premium designer-furniture market.
Interior Units positions its products as replica/reproduction furniture inspired by iconic mid-century designs, rather than representing every product as an original manufacturer product. Its own company information describes its range as reproductions of mid-century, Bauhaus and Scandinavian designs.
That means buyers should evaluate the chair according to what they are actually purchasing.
Authentic/licensed design
- Official production
- Documented provenance
- Premium pricing
- Original manufacturer specifications
Reproduction
- Inspired by the established design
- More accessible pricing
- Materials vary by manufacturer
- Primarily purchased for design, function and value
For shoppers who want the LC4 aesthetic without the premium cost of an officially licensed piece, a well-specified reproduction can be a practical alternative.
How to Style a Black LC4
The easiest way to make the chair look intentional is to give it enough visual space.
With Walnut
Black leather + walnut is a classic mid-century combination.
With Cream
A cream rug or sofa can soften the contrast.
With Marble
Black leather, chrome and marble create a more contemporary luxury look.
With Concrete
For an industrial interior, the metal structure works naturally with concrete surfaces.
With Natural Wood
Oak and black leather create a warmer interpretation of the modernist aesthetic.
The LC4 doesn’t need a crowded background.
Its shape already provides the visual interest.
Is the LC4 Comfortable?
Comfort depends on the construction of the individual product, but the fundamental design is intended for reclining rather than conventional upright sitting.
Before buying, consider:
- Cushion firmness
- Headrest position
- Reclining range
- Frame stability
- User height
- Overall dimensions
- Upholstery feel
Don’t judge comfort solely from product photography.
If you’re comparing an LC4 chaise longue UK option with another model, examine the specifications and customer reviews alongside the photographs.
The current Interior Units listing shows 13 customer ratings with a 5.00/5 displayed score for the Black LC4.
Reviews should still be assessed critically, with particular attention to comments about long-term comfort, delivery, construction and upholstery rather than relying only on the numerical score.
Black LC4 Chaise Longue for UK Buyers
For UK customers, the most important part of the promotion is not just the sticker price.
Consider the total delivered cost.
Interior Units currently promotes free delivery across the UK/EU market, while the website also advertises a 2-year warranty across its furniture range.
Before ordering, check:
- Final checkout price
- Currency
- Delivery destination
- Delivery timeframe
- Warranty conditions
- Returns policy
- First-order discount eligibility
This is particularly important for large furniture because delivery terms can significantly affect the real purchase cost.
Black LC4 Chaise Longue for EU Buyers
For EU shoppers, the current displayed product price provides a straightforward starting point:
€635 sale price
Then:
5% FIRSTORDER5 discount = €603.25
The website currently promotes free delivery throughout Europe.

Why Buy During the Flash Sale?
There are three layers of value in the current offer.
1. Existing Sale Price

Final Verdict: Is the Black LC4 Worth Buying?
If you are searching for a Black LC4 Chaise Longue that combines an iconic modernist silhouette with a more accessible price point, the current Interior Units promotion is worth considering.
The chair is currently listed at €635, down from €950, and the additional 5% first-order discount with code FIRSTORDER5 brings the calculated promotional price to €603.25 before any other applicable checkout adjustments.
For UK and EU buyers, the current free-delivery offer adds another practical advantage.
But the smartest purchase decision is still based on more than the discount.
Check the:
material → construction → dimensions → comfort → reviews → warranty → delivery → final checkout price
If those factors meet your expectations, the current flash promotion makes the Black LC4 Chaise Longue a compelling designer-inspired furniture option for modern interiors.
