I bought steps from Bed bath & beyond a couple of weeks ago.. i think that they were much like the plastic ones that are sold at walmart. They retail for around 30 dollars..... I have a king size bed...... When i opened them...they were tiny. I think like 12 - 14 inched high. These would be good for a couch or chair but not a bed (or my bed, i should say) ... then as some1 else had stated there is an orderfornm to buy an additional riser to make it a 4 stair ..... for 9.99 plus shipping 4.95..... when i was in BB&B there was a guy in there that had asked me y i was buying them... come to find out he will be selling some kind of pet steps on QVC in the middle of June.... I didnt get any specifics on them though.... also, I have seem some soft steps on Ebay that you can get in higher sizes... i think i might try one of those......
