I bought this baby gym from Asda before my baby arrived. It was reduced from the RRP of 32 GBP to half price at 16 GBP, but I notice Asda are now selling these for a lower price of 25 GBP. Activity gyms are a great way for babies to have their senses stimulated, and are a safe way for babies to play when they are too young to sit or stand.
The gym consists of a machine washable playmat, and there are two foam bars which cross over above the mat, forming an arch from which four toys hang. The toys included are basic, but a good basis for sensory play. They consist of a tiger chime toy, a soft mirror, a ring rattle, and a plastic dragonfly which can also be used as a teether. It is also possible to hang your own toys from the bar, and there are additional loops stitched onto the mat so you can attach toys when the baby is having "tummy time".
Constructing the playmat is very simple, although I would recommend being careful when removing the foam bars as they are tightly packed and therefore spring out across the room potentially taking someone's eye out! If you were short on storage or buying this to keep at the grandparent's house, the bars are easily and quickly removed for storage, but we keep ours up permanently since converting our dining room to a playroom.
In use, this playmat holds my baby's attention for a surprising amount of time given that he is basically lying on the floor with some toys dangling above his head. He has used this since birth, and even though he can now sit up, he still loves the freedom of lying on his back and having a good kick around. The mat is also useful for when he's having the recommended tummy time, and practising rolling over. Of course, he could just do this on the rug, but I always think it seems more fun if it's tagged onto playtime. The mat itself isn't very thick, and as we have wooden floors I place ours on a rug in case he gets a bit carried away throwing his head back and bangs his head on the floor.
There is a good combination of toys on this mat. My son loves looking into mirrors and trying to figure out what it is he's looking at, so he always grabs at this first. The chime toy is great for providing entertainment because he hits it occasionally as he's throwing his arms about, and then gets super excited when he hears the chime noise. He only really notices the rattle when I shake it for him, but once I have his attention he will grab hold of it and pull it towards him. The only toy he doesn't really bother with is the teether.
This was a great buy, and something I'm sure we'll continue to get use out of.
