The spring part was fine (we hope!)however, the covering would not go on  zip all the way up (hence the 4 stars rating!). We (my husband and I) tried every way possible and finally had to give that up!  We used a fitted sheet instead!!!  There is no way that covering could have been a Queen size!  
Other than the covering, the comfort and durability remains to be seen!  Company coming for a two weeks stay so, fingers crossed, she’ll be alright with the bed springs, 11” mattress  4” thick lavender memory foam topper - all purchased from y’all!
