I use my day bad like a sofa. I have fooled around with pillows trying to get enough support and comfort, but have not had good success. I'm hoping this bolster will support my back and make my day bed more comfortable.

A cheaper option for my daybed.
ESTHER L on Apr 23, 2017
Perfect for making a foam support in front of a headboard on my wall bed. I can easily remove it when I put the bed up. Price was great. Maybe I should have gone with high density, but for the price, I thought it was worth trying the regular foam first.
LARISSA C on Apr 21, 2017

Can this be used to prop your feet up?
A shopper on Mar 22, 2017
BEST ANSWER: I mean sure? But so can a lot of things. What are you thinking specifically?
What's the difference between high density and normal form? This is for a daybed that's also a bed
A shopper on Aug 17, 2018
BEST ANSWER: Hi density foam will be heavier and firmer. In theory it should also last longer, but it will be less comfortable. I am using normal foam wedges as back rests on a window seat and they're perfect. They feel pleasantly firm and comfortable to lean against. I also sleep on medium density foam and find it very comfortable.
I need a white color for the wedge pillow. do you sell covers? Where can Imget cover for wedge pillow.
A shopper on Mar 3, 2018
BEST ANSWER: We do not sell pillow covers.
Can you cut the 36” long foam wedge to 27” length?
A shopper on Jan 22, 2018
BEST ANSWER: We do not offer custom cuts. This foam can be cut with a serrated or electric knife.
I have a bay window with center 72" wide and 22" deep, would this cushion fit ?
A shopper on Jul 17, 2017
BEST ANSWER: It may be small.

A shopper on Jun 7, 2017
BEST ANSWER: This is a medium density foam.
Can you use for pregnancy to sleep on tummy?
A shopper on Apr 6, 2017

Love it!!!
I love these. I'm using them on twin mattresses that I've made vinyl fitted sheets for as a couch . I plan on purchasing more to fit the mattresses . I found that king-size pillowcase covers do fit over these.

When I opened the box, I thought they must have gotten it wrong. This box is too small. But when I opened it, I he large foam Bolsters were shrink wrapped tightly in a kind of Saran wrap. After cutting them open, they sprang into shape... Very firm and the perfect size. I'm so happy I got them for a good price. I had thought I'd have to have them precision cut for a huge price! Extremely Satisfied!

Love the product
I love my daybed now the foam was just right however I thought I would need four but only needed two. Tried to send two back now I’m stuck with two. Wish I would have read up on the return prosses because returning it was rediculus. Would have cost me $71.00 to ship back.
Before, foam cushion used for back like sofa.
Throw pillows added.
