Donut dog bed recommendations

[florentina1]

My 11 year old, 15 kilo terrier usually sleeps on my bed but she sometimes struggles to get up there. I am considering a donut bed and wonder if anyone has any recommendations.

Aldi have them in at the moment. My greyhound has the XL one and loves it. I've seen fluffier ones though and might treat her for Christmas

TK Maxx /Homesense always have lovely, thick, well insulated ones.
