I do not recommend
Purchased 2  6&#34; Risers for the rear legs of recliner along with 2  4&#34; Risers for the front legs as per PT recommendations.  I am disabled and making recliner higher-up from the floor, helps when trying to stand.  Worked fine for 4 months, then one morning the right rear leg of recliner broke through top (platform) of it.  I weigh about 175lbs., did not move, sit hard or anything unusual to cause break-thru.  I reached over to the right of the recliner, to return, bean type Lap Tray, to its not-in-use location when it occurred.  Have had a friend make a wood frame replacement.  I have read from other's reviews (comments) about similar issues with plastic Risers.
