Status Check

Both the sofa and slipcovers are no longer available from IKEA. The Allerum was discontinued in 2003.

  1. There are 2 different versions of the Allerum from 2 different production batches:
    • W- 195 cm D- 90cm H- 35cm
    • W- 202 cm D- 90cm H- 35cm
  2. Cool Factor: The back support flips backwards and this couch doubles as a twin sized bed. The seat is ultra supportive and comfortable, with a spring core and polyurethane foam.
  3. Ugh Factor: Decorative round cushions are thin and lumpy. Needs constant fluffing, so additional stuffing for the cushions will be helpful.

Not too sure which version of the Allerum you currently own? Luckily, there’s an easy way to distinguish the difference between the two versions.

Simply take a measurement of your Allerum Seat Cushion by measuring the width of the seat cushion, between the seams (on your existing cover). Remember to ignore any piping or the foam that bulges out at the sides to get a more accurate measurement.

Our Review.

The Allerum sofa is comfy with exaggerated dimensions. The bottom cushion is a bit wider and longer than a twin mattress and comes with two round pillows. It’s a cute day bed which is easily turned into an extra sleeper for the occasional overnight guest. Bonus points for being a sleeper with no armrests to accommodate any exceptionally tall guests.

Although this model has been discontinued in IKEA stores, Comfort Works is still producing replacement slipcovers for the IKEA Allerum Sofa Bed.
