I bought this with the Vigour 4 pushchair based on Which review.
No need to buy car seat and carrycot, so overall I think it’s good value for money. Baby can travel safely in recommended lay flat and no need to worry about 2 hour rule so able to fit on chassis of puchchair.
Negatives: Heavy to carry with baby, she is also only 7kg (2 kilos under max weight) but her feet already meet the bottom of the cot- so a bit worried she will outgrow it before she reaches the weight for next size car seat.
I bought the baby safe sleeper after months of debating and I am thrilled with it. My daughter sleeps like a log in it and I can be sure that her health isn’t at risk. Every single medical person that has seen her in it has commented on how good it is. The only downside is the weight – her back is well protected, but mine is suffering from lifting her in and out, but it is a price worth paying!
