A bed can look perfect and still leave you waking with your feet pressed against the footboard or a mattress sliding into gaps at the sides. When a frame does not match standard Irish dimensions, custom size mattresses made to order in Ireland offer a practical route to a better night's sleep.
They suit antique bedsteads, European imports, compact bedrooms and beds built for taller sleepers. The process depends on accurate measurements, a clear idea of comfort, and a realistic conversation about price and delivery.
An established Irish furniture retailer, such as Flanagan Kerins, can offer helpful guidance as you compare frames, mattress styles and room access before placing an order.
Custom Size Mattresses Made to Order in Ireland
A made-to-order mattress is built to the width and length you request. Instead of choosing a stocked size, you give the maker dimensions that suit the inside of your bed frame or support platform.
That differs from buying a standard European or IKEA mattress. These may feel close in name but differ in centimetres. A standard Irish single is usually 90 x 190 cm, while an Irish king is 150 x 200 cm. European sizes often include 140 x 200 cm and 160 x 200 cm.
Bespoke means more than choosing a large size
A true bespoke order can account for unusual lengths, narrow widths, rounded corners or a shallow mattress recess. Some suppliers also offer split designs for adjustable beds or paired mattresses.
Flanagan Kerins has specialist routes for this work. we can make mattresses for Irish, European and IKEA bed sizes, including larger dimensions by request.
Standard sizes still provide a useful starting point
Knowing the nearest standard size helps you describe what you need. It also makes it easier to spot when the mismatch is substantial rather than a minor clearance issue.
A custom mattress does not need to be extravagant. It needs to fit the usable space and give the sleeper proper support. Suppliers usually quote individually by phone, email or an online enquiry rather than displaying one fixed price.

Non-standard mattress sizes for awkward bed frames
Small differences matter more than they appear on paper. A mattress that is five centimetres too narrow can move when you turn. One that is too wide may bow at the edges or refuse to settle onto its base.
Wooden bedsteads also change slightly over time. Natural settling, handmade construction and supplier tolerances can affect the final fit, so measure the actual bed rather than trusting a label.
Extra-long mattresses for taller sleepers and unusual bedrooms
For taller people, a 200 cm mattress can make a noticeable difference. Longer made-to-measure options also suit loft conversions, guest rooms and imported frames designed around continental lengths.
Measure the inside usable length of the frame, not the advertised bed name. Check for a footboard that steals space too. Extra length may change the cost, affect delivery access and limit fitted-sheet choices, so plan for bedding at the same time.
Narrow mattresses for compact rooms and cabins
Box rooms, boats, caravans, mobile homes and bespoke children's furniture often need a width below a standard 90 cm single. A narrower mattress can free valuable floor space without leaving a hard-edged gap beside the bed.
First, inspect the support beneath it. Slats should be secure and close enough for the mattress construction you choose. Also check airflow under the base, access through the property and the availability of fitted sheets in your chosen dimensions.
Antique bed frames with unusual proportions
Antique bedsteads often have enclosed sides, curved ends or shallow wells that do not welcome a modern standard mattress. An old frame can have a charming silhouette but little tolerance for guesswork.
Measure both the current mattress and the frame. If the shape is irregular, send photographs and a simple sketch to the supplier. A standard mattress forced into a tight bed can damage the frame, reduce edge support and make changing sheets harder.
A mattress should sit securely within an enclosed frame, with enough clearance to remove it without scraping the fabric or timber.
European and IKEA bed sizes need exact matching
A bed called a "double" does not guarantee an Irish double mattress will fit. European and IKEA frames use metric sizes that often differ in both width and length.
For example, a 90 x 200 cm European single is 10 cm longer than a standard 90 x 190 cm Irish single. A 140 x 200 cm frame is wider and longer than the common Irish 135 x 190 cm double. Meanwhile, a 160 x 200 cm continental king is 10 cm wider than an Irish 150 x 200 cm king.
IKEA Ireland's mattress size guide lists 80 x 200 cm, 90 x 200 cm, 140 x 200 cm and 160 x 200 cm amongst its common formats. Matching those exact measurements improves the look of the bed and reduces gaps where bedding can catch.
For an imported bed, record the dimensions in centimetres before you shop. This is more reliable than translating the bed's name into an Irish size category.
How to measure a made-to-measure mattress in Ireland
A tape measure, a notepad and ten careful minutes can prevent an expensive mistake. Measure in centimetres and take each measurement more than once, particularly with older frames.
Measure the frame, mattress and room
If your current mattress fits well, measure it at the head, centre and foot. Widths can vary on handmade or aged beds. If there is no suitable mattress, measure the inside width and length of the frame or the full support surface.
Follow these steps before requesting a price:
- Measure the usable mattress space, including any inward-curving sides or posts.
- Check whether the headboard or footboard reduces the length available for your body.
- Allow a small clearance where the mattress sits inside a recessed frame.
- Photograph curved, angled or unusually shaped beds beside your measurements.
- Measure doorways, stair turns and lifts before ordering a large mattress.
A mattress may fit the bed but still fail to reach the bedroom. This is a common issue in narrow hallways and upper-floor rooms.
Confirm height, shape and base support
Length and width are only part of the specification. State the mattress height you want, especially if the bed has low sides or a deep headboard. A thick mattress can hide a beautiful antique rail, while one that is too shallow may leave you sitting uncomfortably low.
Tell the supplier about rounded corners, cut-outs, notches and split sections. Share details of the base too, including slat spacing, a solid platform or an adjustable mechanism. The construction must suit the support beneath it.
Requesting a quotation for a custom mattress
Custom mattress prices vary because every build starts with different measurements, materials and delivery requirements. A clear enquiry saves time and gives the supplier a sound basis for their quote.
Give the supplier the full sleeping picture
Include more than a pair of dimensions. Explain who will use the mattress and how the bed needs to function.
- Provide the exact width, length and preferred finished height in centimetres.
- Say whether you prefer foam, springs or a natural-filled construction.
- Describe your usual sleeping position, body-weight range and preferred firmness.
- Mention allergies, fabric preferences and any unusual shaping.
- Include your delivery address, access details and the date you need the mattress.
- Ask whether the quote includes delivery, old-mattress removal, VAT and special shaping.
Ask about the lead time before you commit, particularly if you are furnishing a new home or preparing a guest room. Custom products may not have the same return terms as standard stocked mattresses, so read the supplier's conditions carefully.
A showroom visit can still help when the finished size is unusual. Try a comparable mattress feel, then discuss how the maker will adapt that construction to your requested dimensions.
Choose comfort as carefully as the dimensions
Perfect measurements alone do not produce restful sleep. The construction, firmness and edges should suit your body, your sleeping habits and the type of base beneath the mattress.
Foam, pocket springs and natural materials
Foam mattresses can work well for lightweight frames and unusual shapes because manufacturers can adapt them more easily. They often give a close, cushioning feel, although the type and depth of foam affect the final result.
Pocket sprung mattresses offer a more traditional response and can allow more air to move through the bed. For couples, individually responding springs may reduce the sensation of a partner moving during the night.
Natural and handcrafted options appeal to shoppers who value breathable fillings and Irish production. However, not every construction can be made in every unusual shape. Confirm that your preferred option is available before settling on the design.
Firmness, edge support and sleeping comfort
Firmness should reflect body weight, sleeping position and personal preference, not mattress size alone. Side sleepers often prefer more pressure relief at the shoulder and hip. Back and front sleepers may favour a flatter, more supportive surface.
Strong edge support matters with antique frames and narrow mattresses, where you may sit close to the side each morning. Couples should also consider movement transfer, particularly if one person sleeps lightly.
Where possible, test a similar model in a showroom. If no sample matches your exact build, ask the supplier to explain the spring system, comfort layers and expected feel. This conversation makes custom size mattresses made to order in Ireland far more personal than a standard online purchase.
A mattress that fits the bed and your sleep
Made-to-order mattresses are a sensible answer for extra-long beds, narrow spaces, antique frames and imported European sizes. Accurate measurements remain the foundation, while the right construction turns that good fit into genuine comfort.
Choose your preferred feel before requesting a quote. Then confirm the size, height, shaping, lead time, delivery details and aftercare with an experienced Irish supplier.
With showroom, online or virtual guidance, you can order a custom mattress that belongs in the frame and supports the way you sleep.
