Short answer: do not begin with a queen, king, or double-bed label. Measure the actual outer bed frame and the place each sleeper's feet touch the floor. Then choose the smallest complete 40 cm grid that makes that landing comfortable without blocking a wardrobe, door, vent, drawer, or cleaning route.
Choose what the bedroom rug needs to do
More carpet under the bed is not automatically better. A large under-bed field visually anchors the furniture, but many of its tiles disappear under a heavy object and become harder to lift. A smaller bedside layout may deliver the comfort you notice every morning with fewer tiles and easier maintenance.
| Placement | What it solves | What to check |
|---|---|---|
| Bedside runner | A soft first step on one or both sides with the lowest tile count | Nightstand legs, walking width, wall clearance, and whether two sides need separate runners |
| Foot-of-bed zone | Frames a bench or open floor area without loading tiles under the whole bed | Clear route around the corners, bench feet, and the exposed raised edge |
| Partial under-bed rug | Connects both sides and the foot in one larger rectangle | How many rows remain exposed, which bed legs sit on tiles, and how hidden tiles will be reached |
| Full under-bed field | Creates the most continuous carpeted look | Moving the bed, furniture indentations, under-bed storage, vents, and access for cleaning or washing |
IKEA's current bedroom rug guidance uses about 50 cm of exposed softness beside a bed as a general reference and also presents runners as an easier-to-air and easier-to-clean option. A 40 cm modular system cannot make exactly 50 cm with complete tiles: one row gives 40 cm and two rows give 80 cm. Tape both widths beside the bed and walk them before ordering.
Measure the bed frame, landing area, and moving parts
Mattress names differ between countries, and the frame can project beyond the mattress. Headboards, side rails, drawers, upholstered edges, and storage bases also change the floor footprint. Use the frame's widest and longest points, then mark the useful carpet that remains visible.
- Measure the complete outer frame.Include projecting rails, feet, headboard supports, and any bench at the foot.
- Mark both landing zones.Sit and stand normally on each side. Measure where heels and the first two steps actually fall.
- Operate every moving part.Open under-bed drawers, wardrobe doors, room doors, and storage lids through their full travel.
- Map fixed services.Keep floor vents, heating controls, outlets, and required airflow clear.
- Round to complete 40 cm modules.Divide each target side by 40 cm, round up, and multiply the completed rows and columns.
- Tape-test the outside edge.Walk around the bed in low light and confirm that no raised edge sits in a tight turn or doorway.
If a robot vacuum must pass under the bed, test the real combination of machine height, bed clearance, and tile thickness. AK27 is 9 mm thick and AK35 is 9.3 mm before any optional accessory. A product being compatible with some robot vacuums does not guarantee clearance for a particular bed and machine.
AK35 or AK27 for a bedroom?
| Feature | AK35 / Attack 350NE | AK27 / Attack 270 |
|---|---|---|
| Tile size | 40 x 40 cm (15.7 x 15.7 in) | 40 x 40 cm (15.7 x 15.7 in) |
| Total thickness | 9.3 mm | 9 mm |

| Lightweight floor-impact class | ΔLL(I)-4 on TOLI's stated flooring test assembly | ΔLL(I)-3 on TOLI's stated flooring test assembly |
| Treatments shown on current product page | No stain-resistant or deodorizing mark | Stain-resistant and deodorizing marks |
| Bedroom starting point | Calm neutral layouts where texture and the higher published impact class lead | Pet households, spill-prone zones, or buyers who prefer cut pile and listed treatments |
AK35 is the natural first bedroom comparison because its low-contrast palette can sit quietly beside wood, linen, and pale bedding. AK27 becomes the stronger practical comparison when a pet sleeps in the room, drinks or cosmetics are likely to spill, or a cat or small dog with dewclaws may catch a loop. TOLI specifically recommends cut pile for that claw-catching risk.
Three complete bedroom layouts
These examples use complete 40 cm AK35 tiles. Open a preset, change any color in the designer, then tape the stated rectangle in the real room. The dimensions describe the carpet, not a promise that it fits a bed-size label.
1. Bedside landing runner
2 x 4 / 8 tiles / 80 x 160 cm. About 2 ft 7 in x 5 ft 3 in. It covers a generous standing strip while every square remains accessible without moving the bed.
Open the 8-tile layout2. Foot-of-bed zone
4 x 3 / 12 tiles / 160 x 120 cm. About 5 ft 3 in x 3 ft 11 in. Use it to frame open floor or a light bench without hiding most of the rug under the bed.
Open the 12-tile layout3. Partial under-bed anchor
5 x 6 / 30 tiles / 200 x 240 cm. About 6 ft 7 in x 7 ft 10 in. Test how much of the 200 cm width remains visible beside your actual frame before accepting the larger tile count.
Open the 30-tile layoutBed legs change the maintenance plan
TOLI warns that concentrated furniture loads can leave indentation marks. A bed may remain in one position for years, so treat every loaded leg as a likely pressure point rather than assuming the pile will look untouched later. Use only load-spreading furniture supports that are suitable for both the carpet tile and the finished floor, and never promise that a visible mark will disappear completely.
Serviceability matters too. A bedside runner can be lifted without moving the frame. A partial under-bed layout may require the bed to be raised before a hidden tile can be washed or replaced. Keep a layout record, mark the backing of spare tiles by color code, and decide who can safely move the furniture before placing a service tile beneath it.
Cleaning, floor heating, and base-floor limits
TOLI makes routine vacuuming the foundation of Fabric Floor care and gives twice weekly as a general home guideline. Under-bed dust may need a crevice tool or a movable runner. For a dirty tile, remove loose soil, hand wash with water and diluted neutral detergent when needed, rinse completely, remove excess water with towels, and shade-dry in a ventilated place. Do not use a washing machine, spin cycle, or dryer, and return a tile only when completely dry.
TOLI lists many finished wood, vinyl, cushion-floor, marble, and ceramic surfaces as compatible examples for suction placement. Carpet, tatami, mortar, and concrete are unsuitable. Some finished wood floors may not grip reliably, so test a sample first; waxes and coatings also need care.
Both current product pages show floor-heating compatibility, but that mark is not blanket approval for every assembly. TOLI says heating can take longer, suction backing can discolor vinyl-finished heated floors, and some heating manufacturers prohibit floor coverings. Check the floor finish and the heating manufacturer's instructions before placing a large under-bed field.
What the sound rating does and does not mean
TOLI's technical table publishes ΔLL(I)-4 for AK35 and ΔLL(I)-3 for AK27 when placed on the stated flooring test assembly. This is useful when comparing the two products for lightweight floor impacts such as footsteps or small objects. It is not a room soundproofing grade, a promise about voices or road noise, or a guarantee that a partial bedside rug will produce the laboratory result across an apartment.
Buying decision: start with the 8-tile bedside runner when comfort and easy care matter most. Move to the 12-tile foot zone when you want visual balance without loading the rug under the frame. Choose the 30-tile partial under-bed layout only after confirming visible landing width, bed-leg support, storage access, floor compatibility, and who will move the bed for maintenance.
