Yes a capsule can be uncomfortable to carry around, but we only really used to keep baby in it for short quick trips into the school or shops.

We had a convertable car seat with DD and then went out and got a capsule as it was a bit fiddly for us having her in the car seat, plus when we knew we were going out, I could feed her, put her in the capsule, where she would fall asleep, finish getting ready and then transfer her to the car all without interuption.

We have brought a second capsule as we are having twins. We were going to buy the new kind, but opted for the older kind, the one with high sides that sits in a big blue bucket(IYKWIM). As when talking to the baby store owner, we had the other one picked but she advised us that on safety testing the bucket one is safer (SNS). This was a cheaper option so I know it wasnt done from a sales point of view.

All the best making your decision.
