We bought this to adapt our Silver Cross Wave from a single to double stroller when our second was born and are very satisfied with quality and comfort. Our children are 17 months apart and it is important to know that you must buy the tandem seat to use the stroller as a double - the included bassinet and regular seat can be interchanged in the upper seat position but only the tandem seat fits on the tandem adapters lower on the stroller (we originally thought we would wait until our second was 3 months to buy the second/tandem seat).
IMPORTANT: ALTHOUGH OUR PISH POSH REP PROMISED WE COULD COMBINE PISH POSH REWARDS WE HAD STOCKED UP ON TOWARD THIS PURCHASE, WE WERE LATER INFORMED THAT WE COULD ONLY USE ONE VOUCHER PER PURCHASE. Pish Posh did not honor the rep's word. Do not rely on obtaining a discount for more than your highest value voucher.
