Just got some Intex Inflatable Pillows at Asda for 51 pence each! They are blue and are flock on one side. They look ok and should free up some space in the car!
Not sure what they are like, but at that price well worth a try me thinks!
Thought I would share in case anyone is interested.
Tesco's also had their value ones reduced, i got mine for 50p each. I wasn't sure they'd be any good but figured at only £2.50 (for the five of us), then it wasn't going to break the bank.
They seem to be ok with a thin pillow on top, and as we normally have two pillows each we'll be saving the room of 5 pillows in the car.
Now, I (and the rest of the family) hate the things. I'd rather sleep without one than use those horrid things
We bought some and have never used them since - in fact I'm sure we left two behind once (on purpose). We got a couple of those Outwell stuff sack pillows too (in with a lot when we bought a tent) and they are just as awful.
We have taken to buying pillows when we get there (usually only about £4 for 4 in bargain shops) and then leaving them behind or if we take some better ones from home then the go behind the children to make them more comfortable whilst piled high with the rest of the 'stuff' and are then left behind as it's usually time to buy new pillows anyway.
